All:

The list seems to be rather quiet since the close of IETF 83 more than a
week ago.  Actions coming out of the side meeting held on March 24
included:

1. Use Case document first draft by middle of April
2. Use Case initial revision by end of April
3. Start of a charter discussion around middle of April (after first draft
Use Case release)

Dave Waltermire has offered to lead development of the Use Case document
and Kent Landfield has offered to lead the subsequent charter discussion.

Dave/Kent: Do either of you have an update you can share?

Adam

Please find a skeleton I-D of the use case document attached with updates to the abstract based on the feedback to date.  If there are no other comments on the abstract I'll start work on the introduction and we can start breaking out use cases and authors for each use case.

Sincerely,
Dave

document?

Adam

Thanks for sending this out.  I like the abstract and the structure of

That is very neat, but I also have a question on the original topic...

Was there any discussion at the meeting in Paris on Asset Identification 
vs. CIM, or has anyone identified a use-case for AI for which CIM is not 
appropriate?  For the sake of making SACM easily adoptable by large 
enterprises with existing CMDB implementations, I strongly advocate 
abandoning AI in favor of CIM.  I'd be happy to discuss how BMC, IBM, 
HP, CA, etc. have been making CIM the centerpiece of their systems 
management offerings for most of the past decade.

Regards,
--David Solin

Hi David,

I would be interested in learning more about CIM and any benefit it may off=
er our efforts.  I anticipate that there will be many similar discussions a=
long these lines, and we will all benefit from a deeper understanding of ex=
isting standards/specifications, specifically where they overlap and where =
they differ.

In that spirit, can you provide more detail about where you see the overlap=
 between CIM and AI for the list?

Regards,

Adam

Subject: Re: [sacm] Status Update Request

That is very neat, but I also have a question on the original topic...

Was there any discussion at the meeting in Paris on Asset Identification vs=
. CIM, or has anyone identified a use-case for AI for which CIM is not appr=
opriate?  For the sake of making SACM easily adoptable by large enterprises=
 with existing CMDB implementations, I strongly advocate abandoning AI in f=
avor of CIM.  I'd be happy to discuss how BMC, IBM, HP, CA, etc. have been =
making CIM the centerpiece of their systems management offerings for most o=
f the past decade.

Hi Dave,

Thanks for sending this out.  I like the abstract and the structure of

the document so far, so no further comments from me on the abstract.
Are you planning to create a first pass at a complete list of use
cases for the document?

Hi Adam,

Certainly!  NIST describes what AI is supposed to be all about as follows:

"Asset identification plays an important role in an organization's 
ability to quickly correlate different sets of information about assets. 
This specification provides the necessary constructs to uniquely 
identify assets based on known identifiers and/or known information 
about the assets. This specification describes the purpose of asset 
identification, a data model for identifying assets, methods for 
identifying assets, and guidance on how to use asset identification. It 
also identifies a number of known use cases for asset identification."

Large systems management vendors and their customers have had the same 
problem for many years.  A vendor may sell a number of different 
products (which were developed by companies they acquired), such as an 
asset management system, an automation system, a change management 
system, a monitoring and event management system, a helpdesk system, and 
so on.  Since, in the case of every large systems management product 
vendor, these products were developed independent of one-another, there 
has always been a fairly strong need to be able to correlate information 
between them.  For instance, if a user creates a helpdesk ticket because 
he's having problem with email, there is a need for an IT administrator 
to be able to correlate events that might be happening on an Exchange 
Server, with an automated patch distribution job, with the owning 
organization for those assets (for chargeback purposes), and back to the 
helpdesk ticket -- so that response times established in service level 
agreements can be tracked and measured appropriately.

The large ISVs have addressed this market need by taking direction from 
ITIL and creating (so-called) CMDB products.  These products provide an 
authoritative system of record about (1) configuration items (AKA a CI; 
in ITIL, any object whose configuration must be managed independently of 
other CIs is a CI), and (2) relationships between CIs, particularly 
service models/service dependencies.  The individual point products in a 
"solution" generally sync up with a "federated" CMDB using an ETL 
process, and must complete a two-way exchange of information that makes 
it possible to: (1) associate any item in the product with any item in 
the CMDB, and (2) vice-versa.  (A number of factors -- scale, legacy 
install base, organizational inertia, individual point-product market 
requirements, interoperability with 3rd-party products, etc. -- make it 
more or less impossible for all the applications to use the same CMDB 
natively).

So, while most of the information about CIs will still reside in the 
individual point products, at least the CMDB can function as a central 
registry containing all the IT services, their SLAs, their relationships 
to CIs, and CI asset (i.e., ownership) information.

It seems to me, therefore, that any use-case that exists for Asset 
Identification must already exist for CMDBs.  At the same time, while I 
am aware of no products currently using AI for any purpose, I am aware 
of several particularly large ones that include CMDBs 
(BMC/Remedy/BladeLogic, HP/Opsware, IBM/Tivoli, CA/Unicenter ... and all 
of their partners), and furthermore, every one of these CMDB products is 
based on a CIM schema.  So there is a standard model for describing 
everything from services, to the objects and configurations upon which 
they depend, to their consumers.  Given the breadth of the protocols 
included in SCAP, CIM would seem like a ready-made model that is not 
only capable of tying everything together, but with the added advantage 
of already being widely used in enterprise systems management product 
suites.

If we do not use CIM natively for these purposes, we will need to create 
a bridge to translate from AI to CIM so that users will be able to 
correlate security automation information with assets and services that 
are already described in their CMDB systems.

Best regards,
--David Solin

For the sake of making SACM easily adoptable by large enterprises with existing CMDB implementations, I strongly advocate abandoning AI in favor of CIM.  I'd be happy to discuss how BMC, IBM, HP, CA, etc. have been making CIM the centerpiece of their systems management offerings for most of the past decade.

That is very neat, but I also have a question on the original topic...

Was there any discussion at the meeting in Paris on Asset Identification vs. CIM, or has anyone identified a use-case for AI for which CIM is not appropriate?  For the sake of making SACM easily adoptable by large enterprises with existing CMDB implementations, I strongly advocate abandoning AI in favor of CIM.  I'd be happy to discuss how BMC, IBM, HP, CA, etc. have been making CIM the centerpiece of their systems management offerings for most of the past decade.

Subject: [sacm] Status Update Request

All:

The list seems to be rather quiet since the close of IETF 83 more
than a week ago.  Actions coming out of the side meeting held on
March 24
included:

1. Use Case document first draft by middle of April 2. Use Case
initial revision by end of April 3. Start of a charter discussion
around middle of April (after first draft Use Case release)

Dave Waltermire has offered to lead development of the Use Case
document and Kent Landfield has offered to lead the subsequent
charter discussion.

Dave/Kent: Do either of you have an update you can share?

Adam

There are at least two considerations:=20

-          Inter-domain multi-sensor data fusion and synthesis

-          Limitations of discovery (instance data resolution)

=20

Inter-domain multi-sensor data fusion and synthesis

This is for all practical purposes the inverse-functional-property or
primary key syntax match problem.

The metadata in AI is designed with the other SCAP metadata in mind
whereas CIM was not and while they may share common keys like IP address
to perform a join, more and more this is not a stable characteristic of
the asset in either domain.  Another consideration here is that CIM
would not have in it something like a CPE identifier, very common key
for synthesis across domains within the SCAP family.  My suggestion here
is that we not look for a single domain to identify an asset but to
ensure that all the data domains (AI, CIM, etc) have in them enough
boundary objects to "join" or synthesize multiple domains.  We should
ensure that all information domains have in it a rich set of stable
characteristics that afford syntactical matching of the metadata for the
purposes of Inter-domain multi-sensor data fusion and synthesis

=20

=20

Limitations of discovery (instance data resolution): Authenticated and
Unauthenticated Discovery=20

Remote automated scanning comes in at least two flavors,
authenticated-scanning and unauthenticated-scanning.  We must keep this
in mind as we look to the design or borrow these metadata formats (AI,
CIM, etc).  Most if not all CMDB assumes the old network management
mindset of nodes-under-management and node-not-under-management.  The
former having an agent installed or some authentication/authorization
provided, the latter assumes an assessment of the target via its target
surface in an unauthenticated manner.  I raise this issue once again
because OVAL for example makes no provision for the assessment to take
place in an unauthenticated manner.   We need to keep this in mind as we
look to populate the metadata of AI as certain fields will only be valid
for authenticated scanning or an agent.  I'm a vendor that has both
types of scanners and I must say that for reasons I will not get into
here, customers deploy unauthenticated scanners across their entire
enterprise and authenticated scanners in targeted scopes.  I raise this
issue because time and time again, customers come back to us with the
unauthenticated scanners having much more identification of end-point
assets than any other authenticated scanner.  This is a sidebar but I
wanted to share this experience having been a supplier of this
technology for the past 12 years.   =20

Hi Tim,

Addressing the problem of uniqueness certainly does not require an 
entirely new data model.  Existing CMDBs have to solve the problem of 
multiple discovery sources, as each product interacting with it is 
potentially another discovery source.  BMC's Atrium CMDB, for instance, 
extends the CIM schema with a reconciliation ID that is used for this 
purpose, and I imagine that's probably not an uncommon solution.  
There's no reason we can't have an Asset Identification specification 
that consists purely of an extension of CIM -- where we can add, for 
instance, a CPE property to existing classes (e.g., OperatingSystem, 
DatabaseSystem ... or perhaps just to the System parent class?).  
Indeed, perhaps that's what you're suggesting?

To my eye, the AI specification looks largely like a subset of CIM, 
except with the addition of the specialized ai:website object (which 
feels like it should be unnecessary).  Why do we want to reinvent the wheel?

Regards,
--David

    Hi Tim,<br>
    <br>
    Addressing the problem of uniqueness certainly does not require an
    entirely new data model.&nbsp; Existing CMDBs have to solve the problem
    of multiple discovery sources, as each product interacting with it
    is potentially another discovery source.&nbsp; BMC's Atrium CMDB, for
    instance, extends the CIM schema with a reconciliation ID that is
    used for this purpose, and I imagine that's probably not an uncommon
    solution.&nbsp; There's no reason we can't have an Asset Identification
    specification that consists purely of an extension of CIM -- where
    we can add, for instance, a CPE property to existing classes (e.g.,
    OperatingSystem, DatabaseSystem ... or perhaps just to the System
    parent class?).&nbsp; Indeed, perhaps that's what you're suggesting?<br>
    <br>
    To my eye, the AI specification looks largely like a subset of CIM,
    except with the addition of the specialized ai:website object (which
    feels like it should be unnecessary).&nbsp; Why do we want to reinvent
    the wheel?<br>
    <br>
    Regards,<br>
    --David<br>

            mind whereas CIM was not and while they may share common

            is not a stable characteristic of the asset in either

            (AI, CIM, etc) have in them enough boundary objects to
            &#8220;join&#8221; or synthesize multiple domains.&nbsp; We should ensure

            must keep this in mind as we look to the design or borrow
            these metadata formats (AI, CIM, etc).&nbsp; Most if not all CMDB
            assumes the old network management mindset of

            unauthenticated manner.&nbsp; I raise this issue once again

            need to keep this in mind as we look to populate the

            will not get into here, customers deploy unauthenticated
            scanners across their entire enterprise and authenticated
            scanners in targeted scopes.&nbsp; I raise this issue because
            time and time again, customers come back to us with the
            unauthenticated scanners having much more identification of
            end-point assets than any other authenticated scanner.&nbsp; This
            is a sidebar but I wanted to share this experience having
            been a supplier of this technology for the past 12 years.&nbsp;

        <p class="MsoNormal" style="margin-bottom:12.0pt">That is very
          neat, but I also have a question on the original topic...<br>
          <br>
          Was there any discussion at the meeting in Paris on Asset
          Identification vs. CIM, or has anyone identified a use-case
          for AI for which CIM is not appropriate?&nbsp; For the sake of
          making SACM easily adoptable by large enterprises with
          existing CMDB implementations, I strongly advocate abandoning
          AI in favor of CIM.&nbsp; I'd be happy to discuss how BMC, IBM, HP,
          CA, etc. have been making CIM the centerpiece of their systems
          management offerings for most of the past decade.<br>

Please find an updated draft attached with roughed out introduction and use case sections that are still missing a good deal of content.  It is my hope that the included use cases can be used as a starting point for discussion and refinement.  They are intended to be fairly abstract and are based on the discussion archives from scap_interest and sacm.  Many of these overlap with existing efforts in the IETF and other SDOs, but have aspects that have been discussed in this context.  They are not listed in any priority order and are likely not comprehensive.  I appologize in advance if I have missed any use cases that are critical to you or your organization.  Please speak up if I have. ;-)

Thoughts?

Sincerely,
David Waltermire

(CybOX=99) is intended as a draft release of an initial major version of =
the CybOX Language that could be utilized for practical operational use =
and integration into other standards efforts. This release consists of =
three primary components: a pair of formal language specifications for =
the core language content and defined objects content, a set of language =
implementation XML schemas (core, common_types, and ~70 defined object =
schemas), and a small initial set of language utilities including an =
initial draft Snort->CybOX transform, an initial draft OpenIOC->CybOX =
transform and a set of CybOX language Python bindings. Recognizing that =
this is the first time that the formal language specifications will be =
available for review and as such will likely generate feedback from new =
stakeholders, this initial major version is being released as a =93draft=94=
 v1.0 with the expectation of cycles of new feedback and revision before =
a =93final=94 v1.0 is released.

CybOX to define their own identifier syntax locally.
> Reordered attributes and elements in numerous types to better reflect =
common usage and priority.

data and for individual observables.

compositions are now contained within a Observable_Composition element =
providing improved simplicity and modularity.
> Removed the Delta element from ObservableType and relocated the =
appropriate portions (Change, Trend, and Frequency) to appropriate =
locations under Stateful_Measure and Event.

abstract type that will allow domain-specific use cases to add in their =

abstract type that will allow addition of tool-specific data.

type that will allow characterizing differing formats or standards of =
indicators that may have led to the identification of the observable =
data.
> Enhanced the Hash structure to capture full fuzzy hashes in addition =
to simple hashes
> Added a new ExtractedFeaturesType that can be used to adorn differing =
objects (e.g., files, memory, etc.) to capture extracted strings, =
imports, functions and code snippets
> Added a ByteRunsType to enable capture of byte runs within various =
objects.
> Added object_reference attribute to DefinedObjectType to better =
support referencing of independently defined Objects from within another =
Object definition.
> Added a generic DataSegmentType to provide a relatively abstract way =
of characterizing data segments that may be written/read/transmitted or =
otherwise utilized in actions or defined in objects.
> =B7        Added several new defined object schemas (API, Code, =
Device, DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry, =
Network_Subnet, Unix_Network_Route_Entry) including an initial set of =
network-centric defined objects.

I echo Luis' comments. It is good to see the inclusion of network
objects. Quick question to the team related to your netflow comment.

I am looking at:

http://cybox.mitre.org/XMLSchema/cybox_core_v1.0%28draft%29.xsd

... and it looks that we renamed it to "Data Flow"?

What is the difference between that and "Packet Traffic"?

I like the inclusion of the network-centric objects.  IPFIX (netflow)
will add an additional perspective from an incident information sharing
standpoint. =20

Hey everyone,

=20

I just wanted to let you all know that CybOX v1.0 (Draft) content is now
live on the website. http://cybox.mitre.org

The release notes are provided inline below.

The key items of note are:

*        The release of two formal specifications for the CybOX language
(one for the core language and one for the defined objects)

*        The XML Schema has gone through extensive improvements for
expressiveness, clarity, consistency, efficiency, alignment to existing
normative references and documentation.

*        This release includes an initial set of language utilities: a
draft Snort -> CybOX transform, a draft OpenIOC -> CybOX transform, and
a set of Python bindings for the CybOX language.

*        The website now includes a small set of content examples. This
set will grow going forward.

This release involved a lot of hard work from a diverse group of people.
Thank you all for your contributions and effort. We could not have done
it without you.

We look forward to everyone's feedback and collaboration as we continue
to improve and mature the CybOX language.

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression
(CybOX(tm)) is intended as a draft release of an initial major version
of the CybOX Language that could be utilized for practical operational
use and integration into other standards efforts. This release consists
of three primary components: a pair of formal language specifications
for the core language content and defined objects content, a set of
language implementation XML schemas (core, common_types, and ~70 defined
object schemas), and a small initial set of language utilities including
an initial draft Snort->CybOX transform, an initial draft OpenIOC->CybOX
transform and a set of CybOX language Python bindings. Recognizing that
this is the first time that the formal language specifications will be
available for review and as such will likely generate feedback from new
stakeholders, this initial major version is being released as a "draft"
v1.0 with the expectation of cycles of new feedback and revision before
a "final" v1.0 is released.

The CybOX v1.0 (Draft) XML schemas include a significant number of
changes from v0.7 to improve:

*       Clarity, documentation, and descriptive formality for reference
and implementation by other standards and users.

*       Consistency, simplicity, and efficiency.

*       Alignment (as appropriate) to existing normative references.

*       Expressiveness of the schema to better support the broad set of
use cases it targets (malware characterization, indicator and incident
data sharing, event management, etc.) including the addition of an
initial set of network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

*	Refinement of namespaces and schema locations for better
effectiveness and flexibility going forward.
*	Normalized all content according to an established set of naming
conventions.
*	Fully annotated all language items (types, attributes, elements,
etc.).
*	Moved several commonly leveraged types out of the core schema
and into common_types.
*	Achieved full typing of entire schema structure such that all
attributes and elements are definitively typed.
*	Changed all identifiers from ID and IDREF types to be QNames
enabling globally unique identifiers and flexibility for domain-specific
users of CybOX to define their own identifier syntax locally.
*	Reordered attributes and elements in numerous types to better
reflect common usage and priority.
*	Added major_version and minor_version attributes for core
schema.
*	Added capability to characterize source of overall observable
package data and for individual observables.
*	Modified the logical composition structure such that any such
compositions are now contained within a Observable_Composition element
providing improved simplicity and modularity.
*	Removed the Delta element from ObservableType and relocated the
appropriate portions (Change, Trend, and Frequency) to appropriate
locations under Stateful_Measure and Event.
*	Added a Domain_Specific_Object_Attributes field to Object
utilizing an abstract type that will allow domain-specific use cases to
add in their own domain-specific attributes for Objects.
*	Added a Tool-Specific_Data field to ToolInformationType
utilizing an abstract type that will allow addition of tool-specific
data.
*	Added an Indicators field to MeasureSourceType utilizing an
abstract type that will allow characterizing differing formats or
standards of indicators that may have led to the identification of the
observable data.
*	Enhanced the Hash structure to capture full fuzzy hashes in
addition to simple hashes
*	Added a new ExtractedFeaturesType that can be used to adorn
differing objects (e.g., files, memory, etc.) to capture extracted
strings, imports, functions and code snippets
*	Added a ByteRunsType to enable capture of byte runs within
various objects.
*	Added object_reference attribute to DefinedObjectType to better
support referencing of independently defined Objects from within another
Object definition.
*	Added a generic DataSegmentType to provide a relatively abstract
way of characterizing data segments that may be written/read/transmitted
or otherwise utilized in actions or defined in objects.

*        Added several new defined object schemas (API, Code, Device,
DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry,
Network_Subnet, Unix_Network_Route_Entry) including an initial set of
network-centric defined objects.

*	Modified every defined object schema with added annotations as
well as minor and in some cases substantive changes to fix errors,
improve consistency and alignment with existing normative references,
and to improve expressiveness in support of the targeted use cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema,
common_types and the defined object schemas is too great to list every
change in these release notes. Detailed difference reports are available
for each individual schema

Thanks Omar.

=20

To answer your question, first let me point out to other readers that
the two entries that Omar is quoting here exist as values in an
enumeration called EventTypeEnum which as its name implies contains a
list of different labels for grouping types (or classes) of events to be
used as low-granularity buckets for characterizing and classifying
events.

Other entries in this enumeration include things like "File Ops (CRUD)",
"Process Mgt", "Authorization (ACL)", etc.

=20

The "Packet Traffic" value is intended to characterize events dealing
with network packet traffic as its name implies.

The "Data Flow" value is intended to characterize events dealing with
forms of data flow at a higher level of abstraction than just packet
traffic. The relationship between these two values could be viewed as
"Packet Traffic" being a more detailed form of "Data Flow" just as the
values "App Layer Traffic" and "HTTP Layer Traffic", also in this
enumeration, could be other levels in this same abstraction stack.

The idea behind the varying levels of abstraction is to leave  buckets
large enough to capture a wide variety of potential event types (e.g.
data flow events other than obvious things like packet traffic) but also
enable the use of smaller more specific buckets when they are
appropriate and commonly used.

Does this make sense?=20

I echo Luis' comments. It is good to see the inclusion of network
objects. Quick question to the team related to your netflow comment.

I am looking at:

... and it looks that we renamed it to "Data Flow"?

Hey everyone,

=20

I just wanted to let you all know that CybOX v1.0 (Draft) content is now
live on the website. http://cybox.mitre.org

The release notes are provided inline below.

The key items of note are:

*        The release of two formal specifications for the CybOX language
(one for the core language and one for the defined objects)

*        The XML Schema has gone through extensive improvements for
expressiveness, clarity, consistency, efficiency, alignment to existing
normative references and documentation.

*        This release includes an initial set of language utilities: a
draft Snort -> CybOX transform, a draft OpenIOC -> CybOX transform, and
a set of Python bindings for the CybOX language.

*        The website now includes a small set of content examples. This
set will grow going forward.

This release involved a lot of hard work from a diverse group of people.
Thank you all for your contributions and effort. We could not have done
it without you.

We look forward to everyone's feedback and collaboration as we continue
to improve and mature the CybOX language.

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression
(CybOX(tm)) is intended as a draft release of an initial major version
of the CybOX Language that could be utilized for practical operational
use and integration into other standards efforts. This release consists
of three primary components: a pair of formal language specifications
for the core language content and defined objects content, a set of
language implementation XML schemas (core, common_types, and ~70 defined
object schemas), and a small initial set of language utilities including
an initial draft Snort->CybOX transform, an initial draft OpenIOC->CybOX
transform and a set of CybOX language Python bindings. Recognizing that
this is the first time that the formal language specifications will be
available for review and as such will likely generate feedback from new
stakeholders, this initial major version is being released as a "draft"
v1.0 with the expectation of cycles of new feedback and revision before
a "final" v1.0 is released.

The CybOX v1.0 (Draft) XML schemas include a significant number of
changes from v0.7 to improve:

*       Clarity, documentation, and descriptive formality for reference
and implementation by other standards and users.

*       Consistency, simplicity, and efficiency.

*       Alignment (as appropriate) to existing normative references.

*       Expressiveness of the schema to better support the broad set of
use cases it targets (malware characterization, indicator and incident
data sharing, event management, etc.) including the addition of an
initial set of network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

*         Refinement of namespaces and schema locations for better
effectiveness and flexibility going forward.

*         Normalized all content according to an established set of
naming conventions.

*         Fully annotated all language items (types, attributes,
elements, etc.).

*         Moved several commonly leveraged types out of the core schema
and into common_types.

*         Achieved full typing of entire schema structure such that all
attributes and elements are definitively typed.

*         Changed all identifiers from ID and IDREF types to be QNames
enabling globally unique identifiers and flexibility for domain-specific
users of CybOX to define their own identifier syntax locally.

*         Reordered attributes and elements in numerous types to better
reflect common usage and priority.

*         Added major_version and minor_version attributes for core
schema.

*         Added capability to characterize source of overall observable
package data and for individual observables.

*         Modified the logical composition structure such that any such
compositions are now contained within a Observable_Composition element
providing improved simplicity and modularity.

*         Removed the Delta element from ObservableType and relocated
the appropriate portions (Change, Trend, and Frequency) to appropriate
locations under Stateful_Measure and Event.

*         Added a Domain_Specific_Object_Attributes field to Object
utilizing an abstract type that will allow domain-specific use cases to
add in their own domain-specific attributes for Objects.

*         Added a Tool-Specific_Data field to ToolInformationType
utilizing an abstract type that will allow addition of tool-specific
data.

*         Added an Indicators field to MeasureSourceType utilizing an
abstract type that will allow characterizing differing formats or
standards of indicators that may have led to the identification of the
observable data.

*         Enhanced the Hash structure to capture full fuzzy hashes in
addition to simple hashes

*         Added a new ExtractedFeaturesType that can be used to adorn
differing objects (e.g., files, memory, etc.) to capture extracted
strings, imports, functions and code snippets

*         Added a ByteRunsType to enable capture of byte runs within
various objects.

*         Added object_reference attribute to DefinedObjectType to
better support referencing of independently defined Objects from within
another Object definition.

*         Added a generic DataSegmentType to provide a relatively
abstract way of characterizing data segments that may be
written/read/transmitted or otherwise utilized in actions or defined in
objects.

*        Added several new defined object schemas (API, Code, Device,
DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry,
Network_Subnet, Unix_Network_Route_Entry) including an initial set of
network-centric defined objects.

*         Modified every defined object schema with added annotations as
well as minor and in some cases substantive changes to fix errors,
improve consistency and alignment with existing normative references,
and to improve expressiveness in support of the targeted use cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema,
common_types and the defined object schemas is too great to list every
change in these release notes. Detailed difference reports are available
for each individual schema

Thank you for sharing the publication of the CybOX specification to the MIT=
RE site, Sean. =20

As an FYI to those who are not familiar with IODEF, I just want to clarify =
that incident descriptions via IODEF already can include network-centric ob=
jects (NetFlow data was specifically considered for this representation) in=
 the IODEF flow class.  If there is something missing, please post to the M=
ILE mailing list and we will track that for possible revision in IODEF to t=
he guidance document.

If CybOX gets submitted to the IETF or another standards body, then we will=
 be able to consider the intersection and how CybOX might be incorporated i=
n IODEF.=20

Thank you,
Kathleen

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression (CybOX=99) i=
s intended as a draft release of an initial major version of the CybOX Lang=
uage that could be utilized for practical operational use and integration i=
nto other standards efforts. This release consists of three primary compone=
nts: a pair of formal language specifications for the core language content=
 and defined objects content, a set of language implementation XML schemas =
(core, common_types, and ~70 defined object schemas), and a small initial s=
et of language utilities including an initial draft Snort->CybOX transform,=
 an initial draft OpenIOC->CybOX transform and a set of CybOX language Pyth=
on bindings. Recognizing that this is the first time that the formal langua=
ge specifications will be available for review and as such will likely gene=
rate feedback from new stakeholders, this initial major version is being re=
leased as a =93draft=94 v1.0 with the expectation of cycles of new feedback=
 and revision before a =93final=94 v1.0 is released.
The CybOX v1.0 (Draft) XML schemas include a significant number of changes =
from v0.7 to improve:
=95       Clarity, documentation, and descriptive formality for reference a=
nd implementation by other standards and users.
=95       Consistency, simplicity, and efficiency.
=95       Alignment (as appropriate) to existing normative references.

=95       Expressiveness of the schema to better support the broad set of u=
se cases it targets (malware characterization, indicator and incident data =
sharing, event management, etc.) including the addition of an initial set o=
f network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

 *   Refinement of namespaces and schema locations for better effectiveness=
 and flexibility going forward.
 *   Normalized all content according to an established set of naming conve=
ntions.
 *   Fully annotated all language items (types, attributes, elements, etc.)=
.
 *   Moved several commonly leveraged types out of the core schema and into=
 common_types.
 *   Achieved full typing of entire schema structure such that all attribut=
es and elements are definitively typed.
 *   Changed all identifiers from ID and IDREF types to be QNames enabling =
globally unique identifiers and flexibility for domain-specific users of Cy=
bOX to define their own identifier syntax locally.
 *   Reordered attributes and elements in numerous types to better reflect =
common usage and priority.
 *   Added major_version and minor_version attributes for core schema.
 *   Added capability to characterize source of overall observable package =
data and for individual observables.
 *   Modified the logical composition structure such that any such composit=
ions are now contained within a Observable_Composition element providing im=
proved simplicity and modularity.
 *   Removed the Delta element from ObservableType and relocated the approp=
riate portions (Change, Trend, and Frequency) to appropriate locations unde=
r Stateful_Measure and Event.
 *   Added a Domain_Specific_Object_Attributes field to Object utilizing an=
 abstract type that will allow domain-specific use cases to add in their ow=
n domain-specific attributes for Objects.
 *   Added a Tool-Specific_Data field to ToolInformationType utilizing an a=
bstract type that will allow addition of tool-specific data.
 *   Added an Indicators field to MeasureSourceType utilizing an abstract t=
ype that will allow characterizing differing formats or standards of indica=
tors that may have led to the identification of the observable data.
 *   Enhanced the Hash structure to capture full fuzzy hashes in addition t=
o simple hashes
 *   Added a new ExtractedFeaturesType that can be used to adorn differing =
objects (e.g., files, memory, etc.) to capture extracted strings, imports, =
functions and code snippets
 *   Added a ByteRunsType to enable capture of byte runs within various obj=
ects.
 *   Added object_reference attribute to DefinedObjectType to better suppor=
t referencing of independently defined Objects from within another Object d=
efinition.
 *   Added a generic DataSegmentType to provide a relatively abstract way o=
f characterizing data segments that may be written/read/transmitted or othe=
rwise utilized in actions or defined in objects.

=95        Added several new defined object schemas (API, Code, Device, DNS=
_Record, Network_Flow, Network_Packet, Network_Route_Entry, Network_Subnet,=
 Unix_Network_Route_Entry) including an initial set of network-centric defi=
ned objects.

 *   Modified every defined object schema with added annotations as well as=
 minor and in some cases substantive changes to fix errors, improve consist=
ency and alignment with existing normative references, and to improve expre=
ssiveness in support of the targeted use cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):
The level of changes within v1.0 (Draft) in the core schema, common_types a=
nd the defined object schemas is too great to list every change in these re=
lease notes. Detailed difference reports are available for each individual =
schema at:http://cybox.mitre.org/XMLSchema/release_notes/cybox_v1.0(draft)_=

I am glad to hear that you find it useful Luis.

We felt that a minimum initial set of network-related objects was an
important part of any sort of 1.0 release.

The initial set of network-related objects for CybOX v1.0 (Draft) includes:
Address, Port, URI, Socket, DNS_Record, DNS_Cache, Network_Flow,
Network_Packet, Network_Route_Entry, Unix_Network_Route_Entry,
Win_Network_Route_Entry, Network_Route, Network_Subnet, and
Win_Network_Share. From our discussions with various knowledgeable parties,
this seemed like a good initial baseline.

 

If any of you experts have suggestions on other objects that would be useful

I like the inclusion of the network-centric objects.  IPFIX (netflow)  will
add an additional perspective from an incident information sharing
standpoint.

Hey everyone,

 

I just wanted to let you all know that CybOX v1.0 (Draft) content is now
live on the website. http://cybox.mitre.org

The release notes are provided inline below.

The key items of note are:

.        The release of two formal specifications for the CybOX language
(one for the core language and one for the defined objects)

.        The XML Schema has gone through extensive improvements for
expressiveness, clarity, consistency, efficiency, alignment to existing
normative references and documentation.

.        This release includes an initial set of language utilities: a draft
Snort -> CybOX transform, a draft OpenIOC -> CybOX transform, and a set of
Python bindings for the CybOX language.

.        The website now includes a small set of content examples. This set
will grow going forward.

This release involved a lot of hard work from a diverse group of people.
Thank you all for your contributions and effort. We could not have done it
without you.

We look forward to everyone's feedback and collaboration as we continue to
improve and mature the CybOX language.

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression (CybOXT) is
intended as a draft release of an initial major version of the CybOX
Language that could be utilized for practical operational use and
integration into other standards efforts. This release consists of three
primary components: a pair of formal language specifications for the core
language content and defined objects content, a set of language
implementation XML schemas (core, common_types, and ~70 defined object
schemas), and a small initial set of language utilities including an initial
draft Snort->CybOX transform, an initial draft OpenIOC->CybOX transform and
a set of CybOX language Python bindings. Recognizing that this is the first
time that the formal language specifications will be available for review
and as such will likely generate feedback from new stakeholders, this
initial major version is being released as a "draft" v1.0 with the
expectation of cycles of new feedback and revision before a "final" v1.0 is
released.

The CybOX v1.0 (Draft) XML schemas include a significant number of changes
from v0.7 to improve:

.       Clarity, documentation, and descriptive formality for reference and
implementation by other standards and users.

.       Consistency, simplicity, and efficiency.

.       Alignment (as appropriate) to existing normative references.

.       Expressiveness of the schema to better support the broad set of use
cases it targets (malware characterization, indicator and incident data
sharing, event management, etc.) including the addition of an initial set of
network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

.        Refinement of namespaces and schema locations for better
effectiveness and flexibility going forward.

.        Normalized all content according to an established set of naming
conventions.

.        Fully annotated all language items (types, attributes, elements,
etc.).

.        Moved several commonly leveraged types out of the core schema and
into common_types.

.        Achieved full typing of entire schema structure such that all
attributes and elements are definitively typed.

.        Changed all identifiers from ID and IDREF types to be QNames
enabling globally unique identifiers and flexibility for domain-specific
users of CybOX to define their own identifier syntax locally.

.        Reordered attributes and elements in numerous types to better
reflect common usage and priority.

.        Added major_version and minor_version attributes for core schema.

.        Added capability to characterize source of overall observable
package data and for individual observables.

.        Modified the logical composition structure such that any such
compositions are now contained within a Observable_Composition element
providing improved simplicity and modularity.

.        Removed the Delta element from ObservableType and relocated the
appropriate portions (Change, Trend, and Frequency) to appropriate locations
under Stateful_Measure and Event.

.        Added a Domain_Specific_Object_Attributes field to Object utilizing
an abstract type that will allow domain-specific use cases to add in their
own domain-specific attributes for Objects.

.        Added a Tool-Specific_Data field to ToolInformationType utilizing
an abstract type that will allow addition of tool-specific data.

.        Added an Indicators field to MeasureSourceType utilizing an
abstract type that will allow characterizing differing formats or standards
of indicators that may have led to the identification of the observable
data.

.        Enhanced the Hash structure to capture full fuzzy hashes in
addition to simple hashes

.        Added a new ExtractedFeaturesType that can be used to adorn
differing objects (e.g., files, memory, etc.) to capture extracted strings,
imports, functions and code snippets

.        Added a ByteRunsType to enable capture of byte runs within various
objects.

.        Added object_reference attribute to DefinedObjectType to better
support referencing of independently defined Objects from within another
Object definition.

.        Added a generic DataSegmentType to provide a relatively abstract
way of characterizing data segments that may be written/read/transmitted or
otherwise utilized in actions or defined in objects.

.        Added several new defined object schemas (API, Code, Device,
DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry,
Network_Subnet, Unix_Network_Route_Entry) including an initial set of
network-centric defined objects.

.        Modified every defined object schema with added annotations as well
as minor and in some cases substantive changes to fix errors, improve
consistency and alignment with existing normative references, and to improve
expressiveness in support of the targeted use cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema, common_types
and the defined object schemas is too great to list every change in these
release notes. Detailed difference reports are available for each individual
schema at:

the CybOX Language that could be utilized for practical operational use =

generate feedback from new stakeholders, this initial major version is =
being released as a &#8220;draft&#8221; v1.0 with the expectation of =

Thanks Omar.

 

To answer your question, first let me point out to other readers that the
two entries that Omar is quoting here exist as values in an enumeration
called EventTypeEnum which as its name implies contains a list of different
labels for grouping types (or classes) of events to be used as
low-granularity buckets for characterizing and classifying events.

Other entries in this enumeration include things like "File Ops (CRUD)",
"Process Mgt", "Authorization (ACL)", etc.

 

The "Packet Traffic" value is intended to characterize events dealing with
network packet traffic as its name implies.

The "Data Flow" value is intended to characterize events dealing with forms
of data flow at a higher level of abstraction than just packet traffic. The
relationship between these two values could be viewed as "Packet Traffic"
being a more detailed form of "Data Flow" just as the values "App Layer
Traffic" and "HTTP Layer Traffic", also in this enumeration, could be other
levels in this same abstraction stack.

The idea behind the varying levels of abstraction is to leave  buckets large
enough to capture a wide variety of potential event types (e.g. data flow
events other than obvious things like packet traffic) but also enable the
use of smaller more specific buckets when they are appropriate and commonly
used.

 

Does this make sense?

I echo Luis' comments. It is good to see the inclusion of network objects.
Quick question to the team related to your netflow comment.

 

I am looking at:

http://cybox.mitre.org/XMLSchema/cybox_core_v1.0%28draft%29.xsd

 

. and it looks that we renamed it to "Data Flow"?

 

<xs:enumeration value="Data Flow">

   <xs:annotation>

        <xs:documentation>Specifies the class of events dealing with data
flow.</xs:documentation>

   </xs:annotation>

</xs:enumeration>

 

 

What is the difference between that and "Packet Traffic"?

 

<xs:enumeration value="Packet Traffic">
   <xs:annotation>
     <xs:documentation>Specifies the class of events dealing with packet
traffic.</xs:documentation>
   </xs:annotation>
</xs:enumeration>

I like the inclusion of the network-centric objects.  IPFIX (netflow)  will
add an additional perspective from an incident information sharing
standpoint.

Hey everyone,

 

I just wanted to let you all know that CybOX v1.0 (Draft) content is now
live on the website. http://cybox.mitre.org

The release notes are provided inline below.

The key items of note are:

.        The release of two formal specifications for the CybOX language
(one for the core language and one for the defined objects)

.        The XML Schema has gone through extensive improvements for
expressiveness, clarity, consistency, efficiency, alignment to existing
normative references and documentation.

.        This release includes an initial set of language utilities: a draft
Snort -> CybOX transform, a draft OpenIOC -> CybOX transform, and a set of
Python bindings for the CybOX language.

.        The website now includes a small set of content examples. This set
will grow going forward.

This release involved a lot of hard work from a diverse group of people.
Thank you all for your contributions and effort. We could not have done it
without you.

We look forward to everyone's feedback and collaboration as we continue to
improve and mature the CybOX language.

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression (CybOXT) is
intended as a draft release of an initial major version of the CybOX
Language that could be utilized for practical operational use and
integration into other standards efforts. This release consists of three
primary components: a pair of formal language specifications for the core
language content and defined objects content, a set of language
implementation XML schemas (core, common_types, and ~70 defined object
schemas), and a small initial set of language utilities including an initial
draft Snort->CybOX transform, an initial draft OpenIOC->CybOX transform and
a set of CybOX language Python bindings. Recognizing that this is the first
time that the formal language specifications will be available for review
and as such will likely generate feedback from new stakeholders, this
initial major version is being released as a "draft" v1.0 with the
expectation of cycles of new feedback and revision before a "final" v1.0 is
released.

The CybOX v1.0 (Draft) XML schemas include a significant number of changes
from v0.7 to improve:

.       Clarity, documentation, and descriptive formality for reference and
implementation by other standards and users.

.       Consistency, simplicity, and efficiency.

.       Alignment (as appropriate) to existing normative references.

.       Expressiveness of the schema to better support the broad set of use
cases it targets (malware characterization, indicator and incident data
sharing, event management, etc.) including the addition of an initial set of
network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

.        Refinement of namespaces and schema locations for better
effectiveness and flexibility going forward.

.        Normalized all content according to an established set of naming
conventions.

.        Fully annotated all language items (types, attributes, elements,
etc.).

.        Moved several commonly leveraged types out of the core schema and
into common_types.

.        Achieved full typing of entire schema structure such that all
attributes and elements are definitively typed.

.        Changed all identifiers from ID and IDREF types to be QNames
enabling globally unique identifiers and flexibility for domain-specific
users of CybOX to define their own identifier syntax locally.

.        Reordered attributes and elements in numerous types to better
reflect common usage and priority.

.        Added major_version and minor_version attributes for core schema.

.        Added capability to characterize source of overall observable
package data and for individual observables.

.        Modified the logical composition structure such that any such
compositions are now contained within a Observable_Composition element
providing improved simplicity and modularity.

.        Removed the Delta element from ObservableType and relocated the
appropriate portions (Change, Trend, and Frequency) to appropriate locations
under Stateful_Measure and Event.

.        Added a Domain_Specific_Object_Attributes field to Object utilizing
an abstract type that will allow domain-specific use cases to add in their
own domain-specific attributes for Objects.

.        Added a Tool-Specific_Data field to ToolInformationType utilizing
an abstract type that will allow addition of tool-specific data.

.        Added an Indicators field to MeasureSourceType utilizing an
abstract type that will allow characterizing differing formats or standards
of indicators that may have led to the identification of the observable
data.

.        Enhanced the Hash structure to capture full fuzzy hashes in
addition to simple hashes

.        Added a new ExtractedFeaturesType that can be used to adorn
differing objects (e.g., files, memory, etc.) to capture extracted strings,
imports, functions and code snippets

.        Added a ByteRunsType to enable capture of byte runs within various
objects.

.        Added object_reference attribute to DefinedObjectType to better
support referencing of independently defined Objects from within another
Object definition.

.        Added a generic DataSegmentType to provide a relatively abstract
way of characterizing data segments that may be written/read/transmitted or
otherwise utilized in actions or defined in objects.

.        Added several new defined object schemas (API, Code, Device,
DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry,
Network_Subnet, Unix_Network_Route_Entry) including an initial set of
network-centric defined objects.

.        Modified every defined object schema with added annotations as well
as minor and in some cases substantive changes to fix errors, improve
consistency and alignment with existing normative references, and to improve
expressiveness in support of the targeted use cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema, common_types
and the defined object schemas is too great to list every change in these
release notes. Detailed difference reports are available for each individual
schema at:

initial draft Snort-&gt;CybOX transform, an initial draft =

generate feedback from new stakeholders, this initial major version is =
being released as a &#8220;draft&#8221; v1.0 with the expectation of =

It is not a euphemism for netflow.

It is about all kinds of data flow not just network-related.

It could be about ETL within a database or datawarehouse.

It could be about data flow within an information system (perhaps =
observable within an application log).

It could be about data flow related to all sorts of forms of message =
passing.

It could be about data flow within data-driven reactive programming =
software architectures.

Etc., Etc.

=E2=80=9CData Flow=E2=80=9D is a fairly abstract bucket acting as a =
classifier for a broad range of potential event types.=20

Of course, we will seek to offer relevant lower abstraction buckets =
within this broad bucket (e.g. =E2=80=9CPacket Traffic=E2=80=9D) to =
offer more specific characterization where we have a clear understanding =
of the sub-bucket but it is still useful to have the broader bucket =
available to catch the things we do not have more specific sub-buckets =
defined for yet.

=20

Does that help clarify?

the two entries that Omar is quoting here exist as values in an =
enumeration called EventTypeEnum which as its name implies contains a =
list of different labels for grouping types (or classes) of events to be =
used as low-granularity buckets for characterizing and classifying =
events.

Other entries in this enumeration include things like =E2=80=9CFile Ops =
(CRUD)=E2=80=9D, =E2=80=9CProcess Mgt=E2=80=9D, =E2=80=9CAuthorization =
(ACL)=E2=80=9D, etc.

=20

The =E2=80=9CPacket Traffic=E2=80=9D value is intended to characterize =
events dealing with network packet traffic as its name implies.

The =E2=80=9CData Flow=E2=80=9D value is intended to characterize events =
dealing with forms of data flow at a higher level of abstraction than =
just packet traffic. The relationship between these two values could be =
viewed as =E2=80=9CPacket Traffic=E2=80=9D being a more detailed form of =
=E2=80=9CData Flow=E2=80=9D just as the values =E2=80=9CApp Layer =
Traffic=E2=80=9D and =E2=80=9CHTTP Layer Traffic=E2=80=9D, also in this =
enumeration, could be other levels in this same abstraction stack.

The idea behind the varying levels of abstraction is to leave  buckets =
large enough to capture a wide variety of potential event types (e.g. =
data flow events other than obvious things like packet traffic) but also =
enable the use of smaller more specific buckets when they are =
appropriate and commonly used.

Does this make sense?=20

Hey everyone,

I just wanted to let you all know that CybOX v1.0 (Draft) content is now =
live on the website. http://cybox.mitre.org

The release notes are provided inline below.

The key items of note are:

=C2=B7        The release of two formal specifications for the CybOX =
language (one for the core language and one for the defined objects)

=C2=B7        The XML Schema has gone through extensive improvements for =
expressiveness, clarity, consistency, efficiency, alignment to existing =
normative references and documentation.

=C2=B7        This release includes an initial set of language =
utilities: a draft Snort -> CybOX transform, a draft OpenIOC -> CybOX =
transform, and a set of Python bindings for the CybOX language.

=C2=B7        The website now includes a small set of content examples. =
This set will grow going forward.

This release involved a lot of hard work from a diverse group of people. =
Thank you all for your contributions and effort. We could not have done =
it without you.

We look forward to everyone=E2=80=99s feedback and collaboration as we =
continue to improve and mature the CybOX language.

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression =
(CybOX=E2=84=A2) is intended as a draft release of an initial major =
version of the CybOX Language that could be utilized for practical =
operational use and integration into other standards efforts. This =
release consists of three primary components: a pair of formal language =
specifications for the core language content and defined objects =
content, a set of language implementation XML schemas (core, =
common_types, and ~70 defined object schemas), and a small initial set =
of language utilities including an initial draft Snort->CybOX transform, =
an initial draft OpenIOC->CybOX transform and a set of CybOX language =
Python bindings. Recognizing that this is the first time that the formal =
language specifications will be available for review and as such will =
likely generate feedback from new stakeholders, this initial major =
version is being released as a =E2=80=9Cdraft=E2=80=9D v1.0 with the =
expectation of cycles of new feedback and revision before a =
=E2=80=9Cfinal=E2=80=9D v1.0 is released.

The CybOX v1.0 (Draft) XML schemas include a significant number of =
changes from v0.7 to improve:

=C2=B7       Clarity, documentation, and descriptive formality for =
reference and implementation by other standards and users.

=C2=B7       Consistency, simplicity, and efficiency.

=C2=B7       Alignment (as appropriate) to existing normative =
references.

=C2=B7       Expressiveness of the schema to better support the broad =
set of use cases it targets (malware characterization, indicator and =
incident data sharing, event management, etc.) including the addition of =
an initial set of network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

=C2=B7        Refinement of namespaces and schema locations for better =
effectiveness and flexibility going forward.

=C2=B7        Normalized all content according to an established set of =
naming conventions.

=C2=B7        Fully annotated all language items (types, attributes, =
elements, etc.).

=C2=B7        Moved several commonly leveraged types out of the core =
schema and into common_types.

=C2=B7        Achieved full typing of entire schema structure such that =
all attributes and elements are definitively typed.

=C2=B7        Changed all identifiers from ID and IDREF types to be =
QNames enabling globally unique identifiers and flexibility for =
domain-specific users of CybOX to define their own identifier syntax =
locally.

=C2=B7        Reordered attributes and elements in numerous types to =
better reflect common usage and priority.

=C2=B7        Added major_version and minor_version attributes for core =
schema.

=C2=B7        Added capability to characterize source of overall =
observable package data and for individual observables.

=C2=B7        Modified the logical composition structure such that any =
such compositions are now contained within a Observable_Composition =
element providing improved simplicity and modularity.

=C2=B7        Removed the Delta element from ObservableType and =
relocated the appropriate portions (Change, Trend, and Frequency) to =
appropriate locations under Stateful_Measure and Event.

=C2=B7        Added a Domain_Specific_Object_Attributes field to Object =
utilizing an abstract type that will allow domain-specific use cases to =
add in their own domain-specific attributes for Objects.

=C2=B7        Added a Tool-Specific_Data field to ToolInformationType =
utilizing an abstract type that will allow addition of tool-specific =
data.

=C2=B7        Added an Indicators field to MeasureSourceType utilizing =
an abstract type that will allow characterizing differing formats or =
standards of indicators that may have led to the identification of the =
observable data.

=C2=B7        Enhanced the Hash structure to capture full fuzzy hashes =
in addition to simple hashes

=C2=B7        Added a new ExtractedFeaturesType that can be used to =
adorn differing objects (e.g., files, memory, etc.) to capture extracted =
strings, imports, functions and code snippets

=C2=B7        Added a ByteRunsType to enable capture of byte runs within =
various objects.

=C2=B7        Added object_reference attribute to DefinedObjectType to =
better support referencing of independently defined Objects from within =
another Object definition.

=C2=B7        Added a generic DataSegmentType to provide a relatively =
abstract way of characterizing data segments that may be =
written/read/transmitted or otherwise utilized in actions or defined in =
objects.

=C2=B7        Added several new defined object schemas (API, Code, =
Device, DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry, =
Network_Subnet, Unix_Network_Route_Entry) including an initial set of =
network-centric defined objects.

=C2=B7        Modified every defined object schema with added =
annotations as well as minor and in some cases substantive changes to =
fix errors, improve consistency and alignment with existing normative =
references, and to improve expressiveness in support of the targeted use =
cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema, =
common_types and the defined object schemas is too great to list every =
change in these release notes. Detailed difference reports are available =
for each individual schema at: =

=E2=80=9Cupper layer=E2=80=9D? Yes, as in higher abstraction.

Just =E2=80=9Cprotocols=E2=80=9D? No.

=20

You guys have been looking at this through the lens of network flow =
which if fine for thinking about that perspective but it is important to =
also realize that the EventTypeEnum and its =E2=80=9CData Flow=E2=80=9D =
value go far beyond network-related scope.

It is about a lot of other types of potential data flows (as I just =
outlined in a response to Tom) that have nothing to do with network =
flow.

=20

Thanks for your response though. This is the kind of discussions that we =
hope to have a lot more of among the various supported communities.

=20

=20

BTW, you may have noticed that the Network_Flow object within CybOX v1.0 =
(Draft) supports expression of netflow within several of the most common =
formats including Netflow9 (as well as IPFIX as Luis pointed out, =
Netflow5 and SiLK as well as bi-directional flow in YAF). The common =
5-tuple or 7-tuple (you describe) (in our case it is an 8-tuple as we =
broke the router interface out into both ingress and egress J) shared by =
pretty much all of the netflow approaches has been broken out into a =
shared Network_Flow_Label structure. The various context-dependent =
portions of the independent approaches are then captured within optional =
structures dedicated to each of them. We hope that eventually the =
community can work to come together towards a single overall common =
expressive structure for netflow that meets the needs of all. We hope =
that CybOX and its use can even help that sort of maturation and =
normalization. But since no such universal structure exists today, we =
decided to enable optional expression of the most common individual =
formats within a single netflow object to serve the large majority of =
relevant users, maintain flexibility and enable discussions and analysis =
of netflow within a common package.

We look forward to continuing discussions with the community to validate =
or invalidate this approach and to refine and mature going forward.

I believe that what Sean is saying is that =E2=80=9Cdata flow=E2=80=9D =
is just a value that is meant for upper layer protocols. But, you have a =
good point. Traditionally, a =E2=80=9Cflow=E2=80=9D in =
=E2=80=9CNetflow=E2=80=9D is based on a set of 5 and up to 7 IP packet =
attributes:

=20

- IP source address

- IP destination address

- Source port

- Destination port

- Layer 3 protocol type

- Class of Service

- Router or switch interface

=20

Although, there is a lot more support with Netflow version 9:

Thanks Omar.

=20

To answer your question, first let me point out to other readers that =
the two entries that Omar is quoting here exist as values in an =
enumeration called EventTypeEnum which as its name implies contains a =
list of different labels for grouping types (or classes) of events to be =
used as low-granularity buckets for characterizing and classifying =
events.

Other entries in this enumeration include things like =E2=80=9CFile Ops =
(CRUD)=E2=80=9D, =E2=80=9CProcess Mgt=E2=80=9D, =E2=80=9CAuthorization =
(ACL)=E2=80=9D, etc.

=20

The =E2=80=9CPacket Traffic=E2=80=9D value is intended to characterize =
events dealing with network packet traffic as its name implies.

The =E2=80=9CData Flow=E2=80=9D value is intended to characterize events =
dealing with forms of data flow at a higher level of abstraction than =
just packet traffic. The relationship between these two values could be =
viewed as =E2=80=9CPacket Traffic=E2=80=9D being a more detailed form of =
=E2=80=9CData Flow=E2=80=9D just as the values =E2=80=9CApp Layer =
Traffic=E2=80=9D and =E2=80=9CHTTP Layer Traffic=E2=80=9D, also in this =
enumeration, could be other levels in this same abstraction stack.

The idea behind the varying levels of abstraction is to leave  buckets =
large enough to capture a wide variety of potential event types (e.g. =
data flow events other than obvious things like packet traffic) but also =
enable the use of smaller more specific buckets when they are =
appropriate and commonly used.

=20

Does this make sense?=20

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression =
(CybOX=E2=84=A2) is intended as a draft release of an initial major =
version of the CybOX Language that could be utilized for practical =
operational use and integration into other standards efforts. This =
release consists of three primary components: a pair of formal language =
specifications for the core language content and defined objects =
content, a set of language implementation XML schemas (core, =
common_types, and ~70 defined object schemas), and a small initial set =
of language utilities including an initial draft Snort->CybOX transform, =
an initial draft OpenIOC->CybOX transform and a set of CybOX language =
Python bindings. Recognizing that this is the first time that the formal =
language specifications will be available for review and as such will =
likely generate feedback from new stakeholders, this initial major =
version is being released as a =E2=80=9Cdraft=E2=80=9D v1.0 with the =
expectation of cycles of new feedback and revision before a =
=E2=80=9Cfinal=E2=80=9D v1.0 is released.

The CybOX v1.0 (Draft) XML schemas include a significant number of =
changes from v0.7 to improve:

=C2=B7       Clarity, documentation, and descriptive formality for =
reference and implementation by other standards and users.

=C2=B7       Consistency, simplicity, and efficiency.

=C2=B7       Alignment (as appropriate) to existing normative =
references.

=C2=B7       Expressiveness of the schema to better support the broad =
set of use cases it targets (malware characterization, indicator and =
incident data sharing, event management, etc.) including the addition of =
an initial set of network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

=C2=B7        Refinement of namespaces and schema locations for better =
effectiveness and flexibility going forward.

=C2=B7        Normalized all content according to an established set of =
naming conventions.

=C2=B7        Fully annotated all language items (types, attributes, =
elements, etc.).

=C2=B7        Moved several commonly leveraged types out of the core =
schema and into common_types.

=C2=B7        Achieved full typing of entire schema structure such that =
all attributes and elements are definitively typed.

=C2=B7        Changed all identifiers from ID and IDREF types to be =
QNames enabling globally unique identifiers and flexibility for =
domain-specific users of CybOX to define their own identifier syntax =
locally.

=C2=B7        Reordered attributes and elements in numerous types to =
better reflect common usage and priority.

=C2=B7        Added major_version and minor_version attributes for core =
schema.

=C2=B7        Added capability to characterize source of overall =
observable package data and for individual observables.

=C2=B7        Modified the logical composition structure such that any =
such compositions are now contained within a Observable_Composition =
element providing improved simplicity and modularity.

=C2=B7        Removed the Delta element from ObservableType and =
relocated the appropriate portions (Change, Trend, and Frequency) to =
appropriate locations under Stateful_Measure and Event.

=C2=B7        Added a Domain_Specific_Object_Attributes field to Object =
utilizing an abstract type that will allow domain-specific use cases to =
add in their own domain-specific attributes for Objects.

=C2=B7        Added a Tool-Specific_Data field to ToolInformationType =
utilizing an abstract type that will allow addition of tool-specific =
data.

=C2=B7        Added an Indicators field to MeasureSourceType utilizing =
an abstract type that will allow characterizing differing formats or =
standards of indicators that may have led to the identification of the =
observable data.

=C2=B7        Enhanced the Hash structure to capture full fuzzy hashes =
in addition to simple hashes

=C2=B7        Added a new ExtractedFeaturesType that can be used to =
adorn differing objects (e.g., files, memory, etc.) to capture extracted =
strings, imports, functions and code snippets

=C2=B7        Added a ByteRunsType to enable capture of byte runs within =
various objects.

=C2=B7        Added object_reference attribute to DefinedObjectType to =
better support referencing of independently defined Objects from within =
another Object definition.

=C2=B7        Added a generic DataSegmentType to provide a relatively =
abstract way of characterizing data segments that may be =
written/read/transmitted or otherwise utilized in actions or defined in =
objects.

=C2=B7        Added several new defined object schemas (API, Code, =
Device, DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry, =
Network_Subnet, Unix_Network_Route_Entry) including an initial set of =
network-centric defined objects.

=C2=B7        Modified every defined object schema with added =
annotations as well as minor and in some cases substantive changes to =
fix errors, improve consistency and alignment with existing normative =
references, and to improve expressiveness in support of the targeted use =
cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema, =
common_types and the defined object schemas is too great to list every =
change in these release notes. Detailed difference reports are available =
for each individual schema at: =

Sean,

=20

Does the overlap between the various objects present a problem?

=20

If there are one or more objects that could carry the same data, then =
human nature means that probability-wise someone will choose data flow =
instead of Netflow.

That is the underlying principle in Murphy=E2=80=99s Law, where you try =
to design it so that there is only one way to do it, and thus private =
Murphy won=E2=80=99t do it the =E2=80=9Cwrong=E2=80=9D way.

=20

Just wondering if these should be mutually exclusive sets.  And designed =
as such.

Might improve interoperability.  (And avoid discussions like this in =
future.)  J

=E2=80=9Cupper layer=E2=80=9D? Yes, as in higher abstraction.

Just =E2=80=9Cprotocols=E2=80=9D? No.

=20

You guys have been looking at this through the lens of network flow =
which if fine for thinking about that perspective but it is important to =
also realize that the EventTypeEnum and its =E2=80=9CData Flow=E2=80=9D =
value go far beyond network-related scope.

It is about a lot of other types of potential data flows (as I just =
outlined in a response to Tom) that have nothing to do with network =
flow.

=20

Thanks for your response though. This is the kind of discussions that we =
hope to have a lot more of among the various supported communities.

=20

=20

BTW, you may have noticed that the Network_Flow object within CybOX v1.0 =
(Draft) supports expression of netflow within several of the most common =
formats including Netflow9 (as well as IPFIX as Luis pointed out, =
Netflow5 and SiLK as well as bi-directional flow in YAF). The common =
5-tuple or 7-tuple (you describe) (in our case it is an 8-tuple as we =
broke the router interface out into both ingress and egress J) shared by =
pretty much all of the netflow approaches has been broken out into a =
shared Network_Flow_Label structure. The various context-dependent =
portions of the independent approaches are then captured within optional =
structures dedicated to each of them. We hope that eventually the =
community can work to come together towards a single overall common =
expressive structure for netflow that meets the needs of all. We hope =
that CybOX and its use can even help that sort of maturation and =
normalization. But since no such universal structure exists today, we =
decided to enable optional expression of the most common individual =
formats within a single netflow object to serve the large majority of =
relevant users, maintain flexibility and enable discussions and analysis =
of netflow within a common package.

We look forward to continuing discussions with the community to validate =
or invalidate this approach and to refine and mature going forward.

I believe that what Sean is saying is that =E2=80=9Cdata flow=E2=80=9D =
is just a value that is meant for upper layer protocols. But, you have a =
good point. Traditionally, a =E2=80=9Cflow=E2=80=9D in =
=E2=80=9CNetflow=E2=80=9D is based on a set of 5 and up to 7 IP packet =
attributes:

=20

- IP source address

- IP destination address

- Source port

- Destination port

- Layer 3 protocol type

- Class of Service

- Router or switch interface

=20

Although, there is a lot more support with Netflow version 9:

If "data flow" is a euphemism for "netflow" is there any reason not to =

Thanks Omar.

=20

To answer your question, first let me point out to other readers that =
the two entries that Omar is quoting here exist as values in an =
enumeration called EventTypeEnum which as its name implies contains a =
list of different labels for grouping types (or classes) of events to be =
used as low-granularity buckets for characterizing and classifying =
events.

Other entries in this enumeration include things like =E2=80=9CFile Ops =
(CRUD)=E2=80=9D, =E2=80=9CProcess Mgt=E2=80=9D, =E2=80=9CAuthorization =
(ACL)=E2=80=9D, etc.

=20

The =E2=80=9CPacket Traffic=E2=80=9D value is intended to characterize =
events dealing with network packet traffic as its name implies.

The =E2=80=9CData Flow=E2=80=9D value is intended to characterize events =
dealing with forms of data flow at a higher level of abstraction than =
just packet traffic. The relationship between these two values could be =
viewed as =E2=80=9CPacket Traffic=E2=80=9D being a more detailed form of =
=E2=80=9CData Flow=E2=80=9D just as the values =E2=80=9CApp Layer =
Traffic=E2=80=9D and =E2=80=9CHTTP Layer Traffic=E2=80=9D, also in this =
enumeration, could be other levels in this same abstraction stack.

The idea behind the varying levels of abstraction is to leave  buckets =
large enough to capture a wide variety of potential event types (e.g. =
data flow events other than obvious things like packet traffic) but also =
enable the use of smaller more specific buckets when they are =
appropriate and commonly used.

=20

Does this make sense?=20

comment.

I am looking at:

Hey everyone,

I just wanted to let you all know that CybOX v1.0 (Draft) content is now =
live on the website. http://cybox.mitre.org

The release notes are provided inline below.

The key items of note are:

=C2=B7        The release of two formal specifications for the CybOX =
language (one for the core language and one for the defined objects)

=C2=B7        The XML Schema has gone through extensive improvements for =
expressiveness, clarity, consistency, efficiency, alignment to existing =
normative references and documentation.

=C2=B7        This release includes an initial set of language =
utilities: a draft Snort -> CybOX transform, a draft OpenIOC -> CybOX =
transform, and a set of Python bindings for the CybOX language.

=C2=B7        The website now includes a small set of content examples. =
This set will grow going forward.

This release involved a lot of hard work from a diverse group of people. =
Thank you all for your contributions and effort. We could not have done =
it without you.

We look forward to everyone=E2=80=99s feedback and collaboration as we =
continue to improve and mature the CybOX language.

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression =
(CybOX=E2=84=A2) is intended as a draft release of an initial major =
version of the CybOX Language that could be utilized for practical =
operational use and integration into other standards efforts. This =
release consists of three primary components: a pair of formal language =
specifications for the core language content and defined objects =
content, a set of language implementation XML schemas (core, =
common_types, and ~70 defined object schemas), and a small initial set =
of language utilities including an initial draft Snort->CybOX transform, =
an initial draft OpenIOC->CybOX transform and a set of CybOX language =
Python bindings. Recognizing that this is the first time that the formal =
language specifications will be available for review and as such will =
likely generate feedback from new stakeholders, this initial major =
version is being released as a =E2=80=9Cdraft=E2=80=9D v1.0 with the =
expectation of cycles of new feedback and revision before a =
=E2=80=9Cfinal=E2=80=9D v1.0 is released.

The CybOX v1.0 (Draft) XML schemas include a significant number of =
changes from v0.7 to improve:

=C2=B7       Clarity, documentation, and descriptive formality for =
reference and implementation by other standards and users.

=C2=B7       Consistency, simplicity, and efficiency.

=C2=B7       Alignment (as appropriate) to existing normative =
references.

=C2=B7       Expressiveness of the schema to better support the broad =
set of use cases it targets (malware characterization, indicator and =
incident data sharing, event management, etc.) including the addition of =
an initial set of network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

=C2=B7       Refinement of namespaces and schema locations for better =
effectiveness and flexibility going forward.

=C2=B7       Normalized all content according to an established set of =
naming conventions.

=C2=B7       Fully annotated all language items (types, attributes, =
elements, etc.).

=C2=B7       Moved several commonly leveraged types out of the core =
schema and into common_types.

=C2=B7       Achieved full typing of entire schema structure such that =
all attributes and elements are definitively typed.

=C2=B7       Changed all identifiers from ID and IDREF types to be =
QNames enabling globally unique identifiers and flexibility for =
domain-specific users of CybOX to define their own identifier syntax =
locally.

=C2=B7       Reordered attributes and elements in numerous types to =
better reflect common usage and priority.

=C2=B7       Added major_version and minor_version attributes for core =
schema.

=C2=B7       Added capability to characterize source of overall =
observable package data and for individual observables.

=C2=B7       Modified the logical composition structure such that any =
such compositions are now contained within a Observable_Composition =
element providing improved simplicity and modularity.

=C2=B7       Removed the Delta element from ObservableType and relocated =
the appropriate portions (Change, Trend, and Frequency) to appropriate =
locations under Stateful_Measure and Event.

=C2=B7       Added a Domain_Specific_Object_Attributes field to Object =
utilizing an abstract type that will allow domain-specific use cases to =
add in their own domain-specific attributes for Objects.

=C2=B7       Added a Tool-Specific_Data field to ToolInformationType =
utilizing an abstract type that will allow addition of tool-specific =
data.

=C2=B7       Added an Indicators field to MeasureSourceType utilizing an =
abstract type that will allow characterizing differing formats or =
standards of indicators that may have led to the identification of the =
observable data.

=C2=B7       Enhanced the Hash structure to capture full fuzzy hashes in =
addition to simple hashes

=C2=B7       Added a new ExtractedFeaturesType that can be used to adorn =
differing objects (e.g., files, memory, etc.) to capture extracted =
strings, imports, functions and code snippets

=C2=B7       Added a ByteRunsType to enable capture of byte runs within =
various objects.

=C2=B7       Added object_reference attribute to DefinedObjectType to =
better support referencing of independently defined Objects from within =
another Object definition.

=C2=B7       Added a generic DataSegmentType to provide a relatively =
abstract way of characterizing data segments that may be =
written/read/transmitted or otherwise utilized in actions or defined in =
objects.

=C2=B7        Added several new defined object schemas (API, Code, =
Device, DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry, =
Network_Subnet, Unix_Network_Route_Entry) including an initial set of =
network-centric defined objects.

=C2=B7       Modified every defined object schema with added annotations =
as well as minor and in some cases substantive changes to fix errors, =
improve consistency and alignment with existing normative references, =
and to improve expressiveness in support of the targeted use cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema, =
common_types and the defined object schemas is too great to list every =
change in these release notes. Detailed difference reports are available =
for each individual schema at: =

Kathleen,

Not sure of the way forward, but comparing data sets could help produce =
a more uniform, normalized one.

I'm still trying to absorb this.  Great work by the way.

I did a scan of the words flow, network, and packet to see how often and =
where they appeared.
It seems that flow is the odd one, while network and packet seem scoped =
to the whole protocol stack with parallel elements in different parts of =
the core doc.
So, I didn't see the low level  (L1-L3) versus high level (L4-L7) =
distinction there.  The network protocol list seems to cover all layers.
BTW, wondering if the non-exhaustive protocol list is intended to be =
extended in the future to call out others at some point.

Also, agree discussion is good one to have.  Helps me to understand =
better.

Mike

Hi Mike,

Are you suggesting to just include the NetConf schema and allow that to =
evolve and pull it in where appropriate?  That makes sense to me...  For =
IODEF, right now you would use the Flow class and could optionally use =
NetConf using the AdditionalData to include another schema.  Although we =
don't have NetConf in the SCI draft, that raises a good point for MILE =
to consider (if there is a gap in schema or guidance).  Or to include =
this in the IODEF guidance document so we have an agreed way to handle =
this use case consistently between implementations.  SACM is thinking =
about the relationships between management protocols and security =
automation specifications in the base use case, so that should help in =
that space.

Understanding the use cases for CybOX and flows may help to understand =
why we may need the representation directly in the specification as =
opposed to referencing NetConf. Sean?

Thanks,
Kathleen

Sean,

Does the overlap between the various objects present a problem?

If there are one or more objects that could carry the same data, then =
human nature means that probability-wise someone will choose data flow =
instead of Netflow.
That is the underlying principle in Murphy=E2=80=99s Law, where you try =
to design it so that there is only one way to do it, and thus private =
Murphy won=E2=80=99t do it the =E2=80=9Cwrong=E2=80=9D way.

Just wondering if these should be mutually exclusive sets.  And designed =
as such.
Might improve interoperability.  (And avoid discussions like this in =
future.)  =E2=98=BA

=E2=80=9Cupper layer=E2=80=9D? Yes, as in higher abstraction.
Just =E2=80=9Cprotocols=E2=80=9D? No.

You guys have been looking at this through the lens of network flow =
which if fine for thinking about that perspective but it is important to =
also realize that the EventTypeEnum and its =E2=80=9CData Flow=E2=80=9D =
value go far beyond network-related scope.
It is about a lot of other types of potential data flows (as I just =
outlined in a response to Tom) that have nothing to do with network =
flow.

Thanks for your response though. This is the kind of discussions that we =
hope to have a lot more of among the various supported communities.


BTW, you may have noticed that the Network_Flow object within CybOX v1.0 =
(Draft) supports expression of netflow within several of the most common =
formats including Netflow9 (as well as IPFIX as Luis pointed out, =
Netflow5 and SiLK as well as bi-directional flow in YAF). The common =
5-tuple or 7-tuple (you describe) (in our case it is an 8-tuple as we =
broke the router interface out into both ingress and egress =E2=98=BA) =
shared by pretty much all of the netflow approaches has been broken out =
into a shared Network_Flow_Label structure. The various =
context-dependent portions of the independent approaches are then =
captured within optional structures dedicated to each of them. We hope =
that eventually the community can work to come together towards a single =
overall common expressive structure for netflow that meets the needs of =
all. We hope that CybOX and its use can even help that sort of =
maturation and normalization. But since no such universal structure =
exists today, we decided to enable optional expression of the most =
common individual formats within a single netflow object to serve the =
large majority of relevant users, maintain flexibility and enable =
discussions and analysis of netflow within a common package.
We look forward to continuing discussions with the community to validate =
or invalidate this approach and to refine and mature going forward.

Sean

I believe that what Sean is saying is that =E2=80=9Cdata flow=E2=80=9D =
is just a value that is meant for upper layer protocols. But, you have a =
good point. Traditionally, a =E2=80=9Cflow=E2=80=9D in =
=E2=80=9CNetflow=E2=80=9D is based on a set of 5 and up to 7 IP packet =
attributes:

- IP source address
- IP destination address
- Source port
- Destination port
- Layer 3 protocol type
- Class of Service
- Router or switch interface

Although, there is a lot more support with Netflow version 9:

If "data flow" is a euphemism for "netflow" is there any reason not to =
call it that?

Thanks Omar.

To answer your question, first let me point out to other readers that =
the two entries that Omar is quoting here exist as values in an =
enumeration called EventTypeEnum which as its name implies contains a =
list of different labels for grouping types (or classes) of events to be =
used as low-granularity buckets for characterizing and classifying =
events.
Other entries in this enumeration include things like =E2=80=9CFile Ops =
(CRUD)=E2=80=9D, =E2=80=9CProcess Mgt=E2=80=9D, =E2=80=9CAuthorization =
(ACL)=E2=80=9D, etc.

The =E2=80=9CPacket Traffic=E2=80=9D value is intended to characterize =
events dealing with network packet traffic as its name implies.
The =E2=80=9CData Flow=E2=80=9D value is intended to characterize events =
dealing with forms of data flow at a higher level of abstraction than =
just packet traffic. The relationship between these two values could be =
viewed as =E2=80=9CPacket Traffic=E2=80=9D being a more detailed form of =
=E2=80=9CData Flow=E2=80=9D just as the values =E2=80=9CApp Layer =
Traffic=E2=80=9D and =E2=80=9CHTTP Layer Traffic=E2=80=9D, also in this =
enumeration, could be other levels in this same abstraction stack.
The idea behind the varying levels of abstraction is to leave  buckets =
large enough to capture a wide variety of potential event types (e.g. =
data flow events other than obvious things like packet traffic) but also =
enable the use of smaller more specific buckets when they are =
appropriate and commonly used.

Does this make sense?

I echo Luis=E2=80=99 comments. It is good to see the inclusion of =
network objects. Quick question to the team related to your netflow =
comment.

I am looking at:
http://cybox.mitre.org/XMLSchema/cybox_core_v1.0%28draft%29.xsd

=E2=80=A6 and it looks that we renamed it to =E2=80=9CData =
Flow=E2=80=9D?

<xs:enumeration value=3D"Data Flow">
   <xs:annotation>
        <xs:documentation>Specifies the class of events dealing with =
data flow.</xs:documentation>
   </xs:annotation>
</xs:enumeration>


What is the difference between that and =E2=80=9CPacket =
Traffic=E2=80=9D?


<xs:enumeration value=3D"Packet Traffic">

   <xs:annotation>

     <xs:documentation>Specifies the class of events dealing with packet =

I like the inclusion of the network-centric objects.  IPFIX (netflow)  =
will add an additional perspective from an incident information sharing =
standpoint.

CybOX v1.0 (Draft) Release Notes
The Version 1.0 (Draft) release of Cyber Observable eXpression =
(CybOX=E2=84=A2) is intended as a draft release of an initial major =
version of the CybOX Language that could be utilized for practical =
operational use and integration into other standards efforts. This =
release consists of three primary components: a pair of formal language =
specifications for the core language content and defined objects =
content, a set of language implementation XML schemas (core, =
common_types, and ~70 defined object schemas), and a small initial set =
of language utilities including an initial draft Snort->CybOX transform, =
an initial draft OpenIOC->CybOX transform and a set of CybOX language =
Python bindings. Recognizing that this is the first time that the formal =
language specifications will be available for review and as such will =
likely generate feedback from new stakeholders, this initial major =
version is being released as a =E2=80=9Cdraft=E2=80=9D v1.0 with the =
expectation of cycles of new feedback and revision before a =
=E2=80=9Cfinal=E2=80=9D v1.0 is released.
The CybOX v1.0 (Draft) XML schemas include a significant number of =
changes from v0.7 to improve:
=E2=80=A2       Clarity, documentation, and descriptive formality for =
reference and implementation by other standards and users.
=E2=80=A2       Consistency, simplicity, and efficiency.
=E2=80=A2       Alignment (as appropriate) to existing normative =
references.

=E2=80=A2       Expressiveness of the schema to better support the broad =
set of use cases it targets (malware characterization, indicator and =
incident data sharing, event management, etc.) including the addition of =
an initial set of network-related defined objects.
Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):
=C2=B7       Refinement of namespaces and schema locations for better =
effectiveness and flexibility going forward.
=C2=B7       Normalized all content according to an established set of =
naming conventions.
=C2=B7       Fully annotated all language items (types, attributes, =
elements, etc.).
=C2=B7       Moved several commonly leveraged types out of the core =
schema and into common_types.
=C2=B7       Achieved full typing of entire schema structure such that =
all attributes and elements are definitively typed.
=C2=B7       Changed all identifiers from ID and IDREF types to be =
QNames enabling globally unique identifiers and flexibility for =
domain-specific users of CybOX to define their own identifier syntax =
locally.
=C2=B7       Reordered attributes and elements in numerous types to =
better reflect common usage and priority.
=C2=B7       Added major_version and minor_version attributes for core =
schema.
=C2=B7       Added capability to characterize source of overall =
observable package data and for individual observables.
=C2=B7       Modified the logical composition structure such that any =
such compositions are now contained within a Observable_Composition =
element providing improved simplicity and modularity.
=C2=B7       Removed the Delta element from ObservableType and relocated =
the appropriate portions (Change, Trend, and Frequency) to appropriate =
locations under Stateful_Measure and Event.
=C2=B7       Added a Domain_Specific_Object_Attributes field to Object =
utilizing an abstract type that will allow domain-specific use cases to =
add in their own domain-specific attributes for Objects.
=C2=B7       Added a Tool-Specific_Data field to ToolInformationType =
utilizing an abstract type that will allow addition of tool-specific =
data.
=C2=B7       Added an Indicators field to MeasureSourceType utilizing an =
abstract type that will allow characterizing differing formats or =
standards of indicators that may have led to the identification of the =
observable data.
=C2=B7       Enhanced the Hash structure to capture full fuzzy hashes in =
addition to simple hashes
=C2=B7       Added a new ExtractedFeaturesType that can be used to adorn =
differing objects (e.g., files, memory, etc.) to capture extracted =
strings, imports, functions and code snippets
=C2=B7       Added a ByteRunsType to enable capture of byte runs within =
various objects.
=C2=B7       Added object_reference attribute to DefinedObjectType to =
better support referencing of independently defined Objects from within =
another Object definition.
=C2=B7       Added a generic DataSegmentType to provide a relatively =
abstract way of characterizing data segments that may be =
written/read/transmitted or otherwise utilized in actions or defined in =
objects.
=E2=80=A2        Added several new defined object schemas (API, Code, =
Device, DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry, =
Network_Subnet, Unix_Network_Route_Entry) including an initial set of =
network-centric defined objects.
=C2=B7       Modified every defined object schema with added annotations =
as well as minor and in some cases substantive changes to fix errors, =
improve consistency and alignment with existing normative references, =
and to improve expressiveness in support of the targeted use cases.
Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):
The level of changes within v1.0 (Draft) in the core schema, =
common_types and the defined object schemas is too great to list every =
change in these release notes. Detailed difference reports are available =
for each individual schema =

Sean,

What you say makes sense.  But, if you will bear with me.  (Still =
learning this.)

=20

If one used Packet Traffic event type always instead of Data Flow event =
type, would some distinction be lost?

Or, put another way, since the packet stuff seems to cover most =
network-based events, does Data Flow involve something that is not on =
the wire?

(Such as an inter-process communication that doesn=E2=80=99t go through =
a protocol stack.)

Mike,

=20

Just to clarify, all of our discussion so far about =E2=80=9CData =
Flow=E2=80=9D and netflow were all in regards to an enumeration called =
EventTypeEnum that simply lets you tag a cyber observable event with a =
type label. It is metadata for an event description.

The only object we have been talking about in any detail so far was the =
Network_Flow object. These two topics are totally independent of each =
other. There is no Data_Flow object.

The abstraction overlap we have been discussing is only in the metadata =
tag applied to an event to characterize what type/class of event it is.

=20

The defined objects themselves (including Network_Flow) have been =
designed to avoid, as much as possible, overlap of the type you =
describe.

The approach we have taken is that where there is common structure and =
meaning relevant to multiple different types of objects, the structure =
for that commonality is broken out into its own object (e.g. Address, =
URI, Port, Account, Process, etc.).

Content based on this common object structure can be embedded within a =
leveraging object (via direct use of the object type) if the content is =
directly relevant only within the context of that object or as an =
independent object and associated to any number of other objects to =
which it is relevant utilizing relationships.

We make no guarantees that we have managed to implement this approach =
flawlessly but we believe that it yields a good balance of consistency, =
efficiency and flexibility. It also allows easy modular use of only what =
is relevant within a given context and enables extension and evolution =
to easily occur in a localized fashion rather than having to extend and =
modify one monolithic structure standard.

=20

Does that make sense?

=20

Sean,

=20

Does the overlap between the various objects present a problem?

=20

If there are one or more objects that could carry the same data, then =
human nature means that probability-wise someone will choose data flow =
instead of Netflow.

That is the underlying principle in Murphy=E2=80=99s Law, where you try =
to design it so that there is only one way to do it, and thus private =
Murphy won=E2=80=99t do it the =E2=80=9Cwrong=E2=80=9D way.

=20

Just wondering if these should be mutually exclusive sets.  And designed =
as such.

Might improve interoperability.  (And avoid discussions like this in =
future.)  J

=E2=80=9Cupper layer=E2=80=9D? Yes, as in higher abstraction.

Just =E2=80=9Cprotocols=E2=80=9D? No.

=20

You guys have been looking at this through the lens of network flow =
which if fine for thinking about that perspective but it is important to =
also realize that the EventTypeEnum and its =E2=80=9CData Flow=E2=80=9D =
value go far beyond network-related scope.

It is about a lot of other types of potential data flows (as I just =
outlined in a response to Tom) that have nothing to do with network =
flow.

=20

Thanks for your response though. This is the kind of discussions that we =
hope to have a lot more of among the various supported communities.

=20

=20

BTW, you may have noticed that the Network_Flow object within CybOX v1.0 =
(Draft) supports expression of netflow within several of the most common =
formats including Netflow9 (as well as IPFIX as Luis pointed out, =
Netflow5 and SiLK as well as bi-directional flow in YAF). The common =
5-tuple or 7-tuple (you describe) (in our case it is an 8-tuple as we =
broke the router interface out into both ingress and egress J) shared by =
pretty much all of the netflow approaches has been broken out into a =
shared Network_Flow_Label structure. The various context-dependent =
portions of the independent approaches are then captured within optional =
structures dedicated to each of them. We hope that eventually the =
community can work to come together towards a single overall common =
expressive structure for netflow that meets the needs of all. We hope =
that CybOX and its use can even help that sort of maturation and =
normalization. But since no such universal structure exists today, we =
decided to enable optional expression of the most common individual =
formats within a single netflow object to serve the large majority of =
relevant users, maintain flexibility and enable discussions and analysis =
of netflow within a common package.

We look forward to continuing discussions with the community to validate =
or invalidate this approach and to refine and mature going forward.

I believe that what Sean is saying is that =E2=80=9Cdata flow=E2=80=9D =
is just a value that is meant for upper layer protocols. But, you have a =
good point. Traditionally, a =E2=80=9Cflow=E2=80=9D in =
=E2=80=9CNetflow=E2=80=9D is based on a set of 5 and up to 7 IP packet =
attributes:

=20

- IP source address

- IP destination address

- Source port

- Destination port

- Layer 3 protocol type

- Class of Service

- Router or switch interface

=20

Although, there is a lot more support with Netflow version 9:

Thanks Omar.

=20

To answer your question, first let me point out to other readers that =
the two entries that Omar is quoting here exist as values in an =
enumeration called EventTypeEnum which as its name implies contains a =
list of different labels for grouping types (or classes) of events to be =
used as low-granularity buckets for characterizing and classifying =
events.

Other entries in this enumeration include things like =E2=80=9CFile Ops =
(CRUD)=E2=80=9D, =E2=80=9CProcess Mgt=E2=80=9D, =E2=80=9CAuthorization =
(ACL)=E2=80=9D, etc.

=20

The =E2=80=9CPacket Traffic=E2=80=9D value is intended to characterize =
events dealing with network packet traffic as its name implies.

The =E2=80=9CData Flow=E2=80=9D value is intended to characterize events =
dealing with forms of data flow at a higher level of abstraction than =
just packet traffic. The relationship between these two values could be =
viewed as =E2=80=9CPacket Traffic=E2=80=9D being a more detailed form of =
=E2=80=9CData Flow=E2=80=9D just as the values =E2=80=9CApp Layer =
Traffic=E2=80=9D and =E2=80=9CHTTP Layer Traffic=E2=80=9D, also in this =
enumeration, could be other levels in this same abstraction stack.

The idea behind the varying levels of abstraction is to leave  buckets =
large enough to capture a wide variety of potential event types (e.g. =
data flow events other than obvious things like packet traffic) but also =
enable the use of smaller more specific buckets when they are =
appropriate and commonly used.

The Version 1.0 (Draft) release of Cyber Observable eXpression =
(CybOX=E2=84=A2) is intended as a draft release of an initial major =
version of the CybOX Language that could be utilized for practical =
operational use and integration into other standards efforts. This =
release consists of three primary components: a pair of formal language =
specifications for the core language content and defined objects =
content, a set of language implementation XML schemas (core, =
common_types, and ~70 defined object schemas), and a small initial set =
of language utilities including an initial draft Snort->CybOX transform, =
an initial draft OpenIOC->CybOX transform and a set of CybOX language =
Python bindings. Recognizing that this is the first time that the formal =
language specifications will be available for review and as such will =
likely generate feedback from new stakeholders, this initial major =
version is being released as a =E2=80=9Cdraft=E2=80=9D v1.0 with the =
expectation of cycles of new feedback and revision before a =
=E2=80=9Cfinal=E2=80=9D v1.0 is released.

The CybOX v1.0 (Draft) XML schemas include a significant number of =
changes from v0.7 to improve:

=C2=B7       Clarity, documentation, and descriptive formality for =
reference and implementation by other standards and users.

=C2=B7       Consistency, simplicity, and efficiency.

=C2=B7       Alignment (as appropriate) to existing normative =
references.

=C2=B7       Expressiveness of the schema to better support the broad =
set of use cases it targets (malware characterization, indicator and =
incident data sharing, event management, etc.) including the addition of =
an initial set of network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

=C2=B7       Refinement of namespaces and schema locations for better =
effectiveness and flexibility going forward.

=C2=B7       Normalized all content according to an established set of =
naming conventions.

=C2=B7       Fully annotated all language items (types, attributes, =
elements, etc.).

=C2=B7       Moved several commonly leveraged types out of the core =
schema and into common_types.

=C2=B7       Achieved full typing of entire schema structure such that =
all attributes and elements are definitively typed.

=C2=B7       Changed all identifiers from ID and IDREF types to be =
QNames enabling globally unique identifiers and flexibility for =
domain-specific users of CybOX to define their own identifier syntax =
locally.

=C2=B7       Reordered attributes and elements in numerous types to =
better reflect common usage and priority.

=C2=B7       Added major_version and minor_version attributes for core =
schema.

=C2=B7       Added capability to characterize source of overall =
observable package data and for individual observables.

=C2=B7       Modified the logical composition structure such that any =
such compositions are now contained within a Observable_Composition =
element providing improved simplicity and modularity.

=C2=B7       Removed the Delta element from ObservableType and relocated =
the appropriate portions (Change, Trend, and Frequency) to appropriate =
locations under Stateful_Measure and Event.

=C2=B7       Added a Domain_Specific_Object_Attributes field to Object =
utilizing an abstract type that will allow domain-specific use cases to =
add in their own domain-specific attributes for Objects.

=C2=B7       Added a Tool-Specific_Data field to ToolInformationType =
utilizing an abstract type that will allow addition of tool-specific =
data.

=C2=B7       Added an Indicators field to MeasureSourceType utilizing an =
abstract type that will allow characterizing differing formats or =
standards of indicators that may have led to the identification of the =
observable data.

=C2=B7       Enhanced the Hash structure to capture full fuzzy hashes in =
addition to simple hashes

=C2=B7       Added a new ExtractedFeaturesType that can be used to adorn =
differing objects (e.g., files, memory, etc.) to capture extracted =
strings, imports, functions and code snippets

=C2=B7       Added a ByteRunsType to enable capture of byte runs within =
various objects.

=C2=B7       Added object_reference attribute to DefinedObjectType to =
better support referencing of independently defined Objects from within =
another Object definition.

=C2=B7       Added a generic DataSegmentType to provide a relatively =
abstract way of characterizing data segments that may be =
written/read/transmitted or otherwise utilized in actions or defined in =
objects.

=C2=B7        Added several new defined object schemas (API, Code, =
Device, DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry, =
Network_Subnet, Unix_Network_Route_Entry) including an initial set of =
network-centric defined objects.

=C2=B7       Modified every defined object schema with added annotations =
as well as minor and in some cases substantive changes to fix errors, =
improve consistency and alignment with existing normative references, =
and to improve expressiveness in support of the targeted use cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema, =
common_types and the defined object schemas is too great to list every =
change in these release notes. Detailed difference reports are available =
for each individual schema at: =

The salient point is IPFIX/Netflow is about accounting details of packet =
traffic summaries (who,what, where, when and how many times).


The following articles could provide the basis for a use case around =
leveraging IPFIX to characterize an observable for information sharing.

> BTW, you may have noticed that the Network_Flow object within CybOX =
v1.0 (Draft) supports expression of netflow within several of the most =
common formats including Netflow9 (as well as IPFIX as Luis pointed out, =
Netflow5 and SiLK as well as bi-directional flow in YAF). The common =
5-tuple or 7-tuple (you describe) (in our case it is an 8-tuple as we =
broke the router interface out into both ingress and egress J) shared by =
pretty much all of the netflow approaches has been broken out into a =
shared Network_Flow_Label structure. The various context-dependent =
portions of the independent approaches are then captured within optional =
structures dedicated to each of them. We hope that eventually the =
community can work to come together towards a single overall common =
expressive structure for netflow that meets the needs of all. We hope =
that CybOX and its use can even help that sort of maturation and =
normalization. But since no such universal structure exists today, we =
decided to enable optional expression of the most common individual =
formats within a single netflow object to serve the large majority of =
relevant users, maintain flexibility and enable discussions and analysis =
of netflow within a common package.

validate or invalidate this approach and to refine and mature going =
forward.

> To answer your question, first let me point out to other readers that =
the two entries that Omar is quoting here exist as values in an =
enumeration called EventTypeEnum which as its name implies contains a =
list of different labels for grouping types (or classes) of events to be =
used as low-granularity buckets for characterizing and classifying =
events.

(CRUD)=94, =93Process Mgt=94, =93Authorization (ACL)=94, etc.

> The =93Packet Traffic=94 value is intended to characterize events =
dealing with network packet traffic as its name implies.
> The =93Data Flow=94 value is intended to characterize events dealing =
with forms of data flow at a higher level of abstraction than just =
packet traffic. The relationship between these two values could be =
viewed as =93Packet Traffic=94 being a more detailed form of =93Data =
Flow=94 just as the values =93App Layer Traffic=94 and =93HTTP Layer =
Traffic=94, also in this enumeration, could be other levels in this same =
abstraction stack.
> The idea behind the varying levels of abstraction is to leave  buckets =
large enough to capture a wide variety of potential event types (e.g. =
data flow events other than obvious things like packet traffic) but also =
enable the use of smaller more specific buckets when they are =
appropriate and commonly used.

> The Version 1.0 (Draft) release of Cyber Observable eXpression =
(CybOX=99) is intended as a draft release of an initial major version of =
the CybOX Language that could be utilized for practical operational use =
and integration into other standards efforts. This release consists of =
three primary components: a pair of formal language specifications for =
the core language content and defined objects content, a set of language =
implementation XML schemas (core, common_types, and ~70 defined object =
schemas), and a small initial set of language utilities including an =
initial draft Snort->CybOX transform, an initial draft OpenIOC->CybOX =
transform and a set of CybOX language Python bindings. Recognizing that =
this is the first time that the formal language specifications will be =
available for review and as such will likely generate feedback from new =
stakeholders, this initial major version is being released as a =93draft=94=
 v1.0 with the expectation of cycles of new feedback and revision before =
a =93final=94 v1.0 is released.
> The CybOX v1.0 (Draft) XML schemas include a significant number of =
changes from v0.7 to improve:

> =B7       Alignment (as appropriate) to existing normative references.
> =B7       Expressiveness of the schema to better support the broad set =
of use cases it targets (malware characterization, indicator and =
incident data sharing, event management, etc.) including the addition of =
an initial set of network-related defined objects.

users of CybOX to define their own identifier syntax locally.

observable package data and for individual observables.

such compositions are now contained within a Observable_Composition =
element providing improved simplicity and modularity.
> =B7       Removed the Delta element from ObservableType and relocated =
the appropriate portions (Change, Trend, and Frequency) to appropriate =
locations under Stateful_Measure and Event.
> =B7       Added a Domain_Specific_Object_Attributes field to Object =

add in their own domain-specific attributes for Objects.
> =B7       Added a Tool-Specific_Data field to ToolInformationType =

data.

abstract type that will allow characterizing differing formats or =
standards of indicators that may have led to the identification of the =
observable data.
> =B7       Enhanced the Hash structure to capture full fuzzy hashes in =
addition to simple hashes
> =B7       Added a new ExtractedFeaturesType that can be used to adorn =
differing objects (e.g., files, memory, etc.) to capture extracted =
strings, imports, functions and code snippets
> =B7       Added a ByteRunsType to enable capture of byte runs within =
various objects.
> =B7       Added object_reference attribute to DefinedObjectType to =
better support referencing of independently defined Objects from within =
another Object definition.
> =B7       Added a generic DataSegmentType to provide a relatively =
abstract way of characterizing data segments that may be =
written/read/transmitted or otherwise utilized in actions or defined in =
objects.
> =B7        Added several new defined object schemas (API, Code, =
Device, DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry, =
Network_Subnet, Unix_Network_Route_Entry) including an initial set of =
network-centric defined objects.
> =B7       Modified every defined object schema with added annotations =
as well as minor and in some cases substantive changes to fix errors, =
improve consistency and alignment with existing normative references, =
and to improve expressiveness in support of the targeted use cases.

Mike,

If you always utilized the most abstract label (Data Flow) to adorn =
events even when you knew the more specific type that they were and had =
a more specific label for them, then yes you would lose distinction.

Such misuse is always the potential downside of enabling flexibility =
through abstraction.

If you know that the event you are characterizing has to do with Packet =
Traffic and not just some form of more general data flow that does not =
have an appropriate associated event type label, then you should =
absolutely use Packet Traffic and not Data Flow. An event should only be =
tagged with an abstract label like Data Flow if there is not an =
appropriate more concrete label available.

=20

In answer to your second question, yes Data Flow definitely covers not =
only network-related events but also events that have nothing to do with =
the wire.

My response to Tom Millar that I sent at 12:52am this morning lists out =
several non-network related types of events that Data Flow could apply =
to.

=20

Please do not feel bad for asking these questions. They help you =
understand our approach, they help others understand our approach, they =
help us better understand the perspective of the communities we are =
targeting to support, they help us uncover issues with our approach or =
implementation, and they help us understand where we need to explain =
ourselves better.

=20

Thank you for the constructive discourse.

Sean,

What you say makes sense.  But, if you will bear with me.  (Still =
learning this.)

=20

If one used Packet Traffic event type always instead of Data Flow event =
type, would some distinction be lost?

Or, put another way, since the packet stuff seems to cover most =
network-based events, does Data Flow involve something that is not on =
the wire?

(Such as an inter-process communication that doesn=E2=80=99t go through =
a protocol stack.)

EventTypeEnum that simply lets you tag a cyber observable event with a =
type label. It is metadata for an event description.

The only object we have been talking about in any detail so far was the =
Network_Flow object. These two topics are totally independent of each =
other. There is no Data_Flow object.

The abstraction overlap we have been discussing is only in the metadata =
tag applied to an event to characterize what type/class of event it is.

=20

The defined objects themselves (including Network_Flow) have been =
designed to avoid, as much as possible, overlap of the type you =
describe.

The approach we have taken is that where there is common structure and =
meaning relevant to multiple different types of objects, the structure =
for that commonality is broken out into its own object (e.g. Address, =
URI, Port, Account, Process, etc.).

Content based on this common object structure can be embedded within a =
leveraging object (via direct use of the object type) if the content is =
directly relevant only within the context of that object or as an =
independent object and associated to any number of other objects to =
which it is relevant utilizing relationships.

We make no guarantees that we have managed to implement this approach =
flawlessly but we believe that it yields a good balance of consistency, =
efficiency and flexibility. It also allows easy modular use of only what =
is relevant within a given context and enables extension and evolution =
to easily occur in a localized fashion rather than having to extend and =
modify one monolithic structure standard.

=20

Does that make sense?

Sean,

=20

Does the overlap between the various objects present a problem?

=20

If there are one or more objects that could carry the same data, then =
human nature means that probability-wise someone will choose data flow =
instead of Netflow.

That is the underlying principle in Murphy=E2=80=99s Law, where you try =
to design it so that there is only one way to do it, and thus private =
Murphy won=E2=80=99t do it the =E2=80=9Cwrong=E2=80=9D way.

=20

Just wondering if these should be mutually exclusive sets.  And designed =
as such.

Might improve interoperability.  (And avoid discussions like this in =
future.)  J

=E2=80=9Cupper layer=E2=80=9D? Yes, as in higher abstraction.

Just =E2=80=9Cprotocols=E2=80=9D? No.

=20

You guys have been looking at this through the lens of network flow =
which if fine for thinking about that perspective but it is important to =
also realize that the EventTypeEnum and its =E2=80=9CData Flow=E2=80=9D =
value go far beyond network-related scope.

It is about a lot of other types of potential data flows (as I just =
outlined in a response to Tom) that have nothing to do with network =
flow.

=20

Thanks for your response though. This is the kind of discussions that we =
hope to have a lot more of among the various supported communities.

=20

=20

BTW, you may have noticed that the Network_Flow object within CybOX v1.0 =
(Draft) supports expression of netflow within several of the most common =
formats including Netflow9 (as well as IPFIX as Luis pointed out, =
Netflow5 and SiLK as well as bi-directional flow in YAF). The common =
5-tuple or 7-tuple (you describe) (in our case it is an 8-tuple as we =
broke the router interface out into both ingress and egress J) shared by =
pretty much all of the netflow approaches has been broken out into a =
shared Network_Flow_Label structure. The various context-dependent =
portions of the independent approaches are then captured within optional =
structures dedicated to each of them. We hope that eventually the =
community can work to come together towards a single overall common =
expressive structure for netflow that meets the needs of all. We hope =
that CybOX and its use can even help that sort of maturation and =
normalization. But since no such universal structure exists today, we =
decided to enable optional expression of the most common individual =
formats within a single netflow object to serve the large majority of =
relevant users, maintain flexibility and enable discussions and analysis =
of netflow within a common package.

We look forward to continuing discussions with the community to validate =
or invalidate this approach and to refine and mature going forward.

I believe that what Sean is saying is that =E2=80=9Cdata flow=E2=80=9D =
is just a value that is meant for upper layer protocols. But, you have a =
good point. Traditionally, a =E2=80=9Cflow=E2=80=9D in =
=E2=80=9CNetflow=E2=80=9D is based on a set of 5 and up to 7 IP packet =
attributes:

- IP source address

- IP destination address

- Source port

- Destination port

- Layer 3 protocol type

- Class of Service

- Router or switch interface

=20

Although, there is a lot more support with Netflow version 9:

Thanks Omar.

=20

To answer your question, first let me point out to other readers that =
the two entries that Omar is quoting here exist as values in an =
enumeration called EventTypeEnum which as its name implies contains a =
list of different labels for grouping types (or classes) of events to be =
used as low-granularity buckets for characterizing and classifying =
events.

Other entries in this enumeration include things like =E2=80=9CFile Ops =
(CRUD)=E2=80=9D, =E2=80=9CProcess Mgt=E2=80=9D, =E2=80=9CAuthorization =
(ACL)=E2=80=9D, etc.

=20

The =E2=80=9CPacket Traffic=E2=80=9D value is intended to characterize =
events dealing with network packet traffic as its name implies.

The =E2=80=9CData Flow=E2=80=9D value is intended to characterize events =
dealing with forms of data flow at a higher level of abstraction than =
just packet traffic. The relationship between these two values could be =
viewed as =E2=80=9CPacket Traffic=E2=80=9D being a more detailed form of =
=E2=80=9CData Flow=E2=80=9D just as the values =E2=80=9CApp Layer =
Traffic=E2=80=9D and =E2=80=9CHTTP Layer Traffic=E2=80=9D, also in this =
enumeration, could be other levels in this same abstraction stack.

The idea behind the varying levels of abstraction is to leave  buckets =
large enough to capture a wide variety of potential event types (e.g. =
data flow events other than obvious things like packet traffic) but also =
enable the use of smaller more specific buckets when they are =
appropriate and commonly used.

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression =
(CybOX=E2=84=A2) is intended as a draft release of an initial major =
version of the CybOX Language that could be utilized for practical =
operational use and integration into other standards efforts. This =
release consists of three primary components: a pair of formal language =
specifications for the core language content and defined objects =
content, a set of language implementation XML schemas (core, =
common_types, and ~70 defined object schemas), and a small initial set =
of language utilities including an initial draft Snort->CybOX transform, =
an initial draft OpenIOC->CybOX transform and a set of CybOX language =
Python bindings. Recognizing that this is the first time that the formal =
language specifications will be available for review and as such will =
likely generate feedback from new stakeholders, this initial major =
version is being released as a =E2=80=9Cdraft=E2=80=9D v1.0 with the =
expectation of cycles of new feedback and revision before a =
=E2=80=9Cfinal=E2=80=9D v1.0 is released.

The CybOX v1.0 (Draft) XML schemas include a significant number of =
changes from v0.7 to improve:

=C2=B7       Clarity, documentation, and descriptive formality for =
reference and implementation by other standards and users.

=C2=B7       Consistency, simplicity, and efficiency.

=C2=B7       Alignment (as appropriate) to existing normative =
references.

=C2=B7       Expressiveness of the schema to better support the broad =
set of use cases it targets (malware characterization, indicator and =
incident data sharing, event management, etc.) including the addition of =
an initial set of network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

=C2=B7       Refinement of namespaces and schema locations for better =
effectiveness and flexibility going forward.

=C2=B7       Normalized all content according to an established set of =
naming conventions.

=C2=B7       Fully annotated all language items (types, attributes, =
elements, etc.).

=C2=B7       Moved several commonly leveraged types out of the core =
schema and into common_types.

=C2=B7       Achieved full typing of entire schema structure such that =
all attributes and elements are definitively typed.

=C2=B7       Changed all identifiers from ID and IDREF types to be =
QNames enabling globally unique identifiers and flexibility for =
domain-specific users of CybOX to define their own identifier syntax =
locally.

=C2=B7       Reordered attributes and elements in numerous types to =
better reflect common usage and priority.

=C2=B7       Added major_version and minor_version attributes for core =
schema.

=C2=B7       Added capability to characterize source of overall =
observable package data and for individual observables.

=C2=B7       Modified the logical composition structure such that any =
such compositions are now contained within a Observable_Composition =
element providing improved simplicity and modularity.

=C2=B7       Removed the Delta element from ObservableType and relocated =
the appropriate portions (Change, Trend, and Frequency) to appropriate =
locations under Stateful_Measure and Event.

=C2=B7       Added a Domain_Specific_Object_Attributes field to Object =
utilizing an abstract type that will allow domain-specific use cases to =
add in their own domain-specific attributes for Objects.

=C2=B7       Added a Tool-Specific_Data field to ToolInformationType =
utilizing an abstract type that will allow addition of tool-specific =
data.

=C2=B7       Added an Indicators field to MeasureSourceType utilizing an =
abstract type that will allow characterizing differing formats or =
standards of indicators that may have led to the identification of the =
observable data.

=C2=B7       Enhanced the Hash structure to capture full fuzzy hashes in =
addition to simple hashes

=C2=B7       Added a new ExtractedFeaturesType that can be used to adorn =
differing objects (e.g., files, memory, etc.) to capture extracted =
strings, imports, functions and code snippets

=C2=B7       Added a ByteRunsType to enable capture of byte runs within =
various objects.

=C2=B7       Added object_reference attribute to DefinedObjectType to =
better support referencing of independently defined Objects from within =
another Object definition.

=C2=B7       Added a generic DataSegmentType to provide a relatively =
abstract way of characterizing data segments that may be =
written/read/transmitted or otherwise utilized in actions or defined in =
objects.

=C2=B7        Added several new defined object schemas (API, Code, =
Device, DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry, =
Network_Subnet, Unix_Network_Route_Entry) including an initial set of =
network-centric defined objects.

=C2=B7       Modified every defined object schema with added annotations =
as well as minor and in some cases substantive changes to fix errors, =
improve consistency and alignment with existing normative references, =
and to improve expressiveness in support of the targeted use cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema, =
common_types and the defined object schemas is too great to list every =
change in these release notes. Detailed difference reports are available =
for each individual schema at: =

I would argue that it is not a problem of uniqueness but a machine
learning problem of computing inter-domain equivalence (which may or may
not be unique).  I say this only because in these case we are talking
about computing the syntactical equivalence but certainly in the future
we could also do this based on semantic equivalence. =20

=20

And you are so right in that CIM would require more schema to aid in the
task of synthesis with sacm/scap.  I'm completely in agreement at the
technical level.    In fact, most of the fields in AI can be computed
from the CIM model (being a subset). =20

=20

What I am sensitive to here is the administrative realms and political
realms of both standards.  If the solution couples the two standards
such that one is impaired by the others progress or dormancy, bad
design, no donut. =20

Hi Tim,

Addressing the problem of uniqueness certainly does not require an
entirely new data model.  Existing CMDBs have to solve the problem of
multiple discovery sources, as each product interacting with it is
potentially another discovery source.  BMC's Atrium CMDB, for instance,
extends the CIM schema with a reconciliation ID that is used for this
purpose, and I imagine that's probably not an uncommon solution.
There's no reason we can't have an Asset Identification specification
that consists purely of an extension of CIM -- where we can add, for
instance, a CPE property to existing classes (e.g., OperatingSystem,
DatabaseSystem ... or perhaps just to the System parent class?).
Indeed, perhaps that's what you're suggesting?

To my eye, the AI specification looks largely like a subset of CIM,
except with the addition of the specialized ai:website object (which
feels like it should be unnecessary).  Why do we want to reinvent the
wheel?

Regards,
--David

There are at least two considerations:=20

-          Inter-domain multi-sensor data fusion and synthesis

-          Limitations of discovery (instance data resolution)

=20

Inter-domain multi-sensor data fusion and synthesis

This is for all practical purposes the inverse-functional-property or
primary key syntax match problem.

The metadata in AI is designed with the other SCAP metadata in mind
whereas CIM was not and while they may share common keys like IP address
to perform a join, more and more this is not a stable characteristic of
the asset in either domain.  Another consideration here is that CIM
would not have in it something like a CPE identifier, very common key
for synthesis across domains within the SCAP family.  My suggestion here
is that we not look for a single domain to identify an asset but to
ensure that all the data domains (AI, CIM, etc) have in them enough
boundary objects to "join" or synthesize multiple domains.  We should
ensure that all information domains have in it a rich set of stable
characteristics that afford syntactical matching of the metadata for the
purposes of Inter-domain multi-sensor data fusion and synthesis

=20

=20

Limitations of discovery (instance data resolution): Authenticated and
Unauthenticated Discovery=20

Remote automated scanning comes in at least two flavors,
authenticated-scanning and unauthenticated-scanning.  We must keep this
in mind as we look to the design or borrow these metadata formats (AI,
CIM, etc).  Most if not all CMDB assumes the old network management
mindset of nodes-under-management and node-not-under-management.  The
former having an agent installed or some authentication/authorization
provided, the latter assumes an assessment of the target via its target
surface in an unauthenticated manner.  I raise this issue once again
because OVAL for example makes no provision for the assessment to take
place in an unauthenticated manner.   We need to keep this in mind as we
look to populate the metadata of AI as certain fields will only be valid
for authenticated scanning or an agent.  I'm a vendor that has both
types of scanners and I must say that for reasons I will not get into
here, customers deploy unauthenticated scanners across their entire
enterprise and authenticated scanners in targeted scopes.  I raise this
issue because time and time again, customers come back to us with the
unauthenticated scanners having much more identification of end-point
assets than any other authenticated scanner.  This is a sidebar but I
wanted to share this experience having been a supplier of this
technology for the past 12 years.   =20

That is very neat, but I also have a question on the original topic...

Was there any discussion at the meeting in Paris on Asset Identification
vs. CIM, or has anyone identified a use-case for AI for which CIM is not
appropriate?  For the sake of making SACM easily adoptable by large
enterprises with existing CMDB implementations, I strongly advocate
abandoning AI in favor of CIM.  I'd be happy to discuss how BMC, IBM,
HP, CA, etc. have been making CIM the centerpiece of their systems
management offerings for most of the past decade.

		Hi Dave,

		Thanks for sending this out.  I like the abstract and
the structure of

the abstract.

Mike,

=20

Just to clarify, all of our discussion so far about =E2=80=9CData =
Flow=E2=80=9D and netflow were all in regards to an enumeration called =
EventTypeEnum that simply lets you tag a cyber observable event with a =
type label. It is metadata for an event description.

The only object we have been talking about in any detail so far was the =
Network_Flow object. These two topics are totally independent of each =
other. There is no Data_Flow object.

The abstraction overlap we have been discussing is only in the metadata =
tag applied to an event to characterize what type/class of event it is.

=20

The defined objects themselves (including Network_Flow) have been =
designed to avoid, as much as possible, overlap of the type you =
describe.

The approach we have taken is that where there is common structure and =
meaning relevant to multiple different types of objects, the structure =
for that commonality is broken out into its own object (e.g. Address, =
URI, Port, Account, Process, etc.).

Content based on this common object structure can be embedded within a =
leveraging object (via direct use of the object type) if the content is =
directly relevant only within the context of that object or as an =
independent object and associated to any number of other objects to =
which it is relevant utilizing relationships.

We make no guarantees that we have managed to implement this approach =
flawlessly but we believe that it yields a good balance of consistency, =
efficiency and flexibility. It also allows easy modular use of only what =
is relevant within a given context and enables extension and evolution =
to easily occur in a localized fashion rather than having to extend and =
modify one monolithic structure standard.

=20

Does that make sense?

=20

Sean,

=20

Does the overlap between the various objects present a problem?

=20

If there are one or more objects that could carry the same data, then =
human nature means that probability-wise someone will choose data flow =
instead of Netflow.

That is the underlying principle in Murphy=E2=80=99s Law, where you try =
to design it so that there is only one way to do it, and thus private =
Murphy won=E2=80=99t do it the =E2=80=9Cwrong=E2=80=9D way.

=20

Just wondering if these should be mutually exclusive sets.  And designed =
as such.

Might improve interoperability.  (And avoid discussions like this in =
future.)  J

=E2=80=9Cupper layer=E2=80=9D? Yes, as in higher abstraction.

Just =E2=80=9Cprotocols=E2=80=9D? No.

=20

You guys have been looking at this through the lens of network flow =
which if fine for thinking about that perspective but it is important to =
also realize that the EventTypeEnum and its =E2=80=9CData Flow=E2=80=9D =
value go far beyond network-related scope.

It is about a lot of other types of potential data flows (as I just =
outlined in a response to Tom) that have nothing to do with network =
flow.

=20

Thanks for your response though. This is the kind of discussions that we =
hope to have a lot more of among the various supported communities.

=20

=20

BTW, you may have noticed that the Network_Flow object within CybOX v1.0 =
(Draft) supports expression of netflow within several of the most common =
formats including Netflow9 (as well as IPFIX as Luis pointed out, =
Netflow5 and SiLK as well as bi-directional flow in YAF). The common =
5-tuple or 7-tuple (you describe) (in our case it is an 8-tuple as we =
broke the router interface out into both ingress and egress J) shared by =
pretty much all of the netflow approaches has been broken out into a =
shared Network_Flow_Label structure. The various context-dependent =
portions of the independent approaches are then captured within optional =
structures dedicated to each of them. We hope that eventually the =
community can work to come together towards a single overall common =
expressive structure for netflow that meets the needs of all. We hope =
that CybOX and its use can even help that sort of maturation and =
normalization. But since no such universal structure exists today, we =
decided to enable optional expression of the most common individual =
formats within a single netflow object to serve the large majority of =
relevant users, maintain flexibility and enable discussions and analysis =
of netflow within a common package.

We look forward to continuing discussions with the community to validate =
or invalidate this approach and to refine and mature going forward.

I believe that what Sean is saying is that =E2=80=9Cdata flow=E2=80=9D =
is just a value that is meant for upper layer protocols. But, you have a =
good point. Traditionally, a =E2=80=9Cflow=E2=80=9D in =
=E2=80=9CNetflow=E2=80=9D is based on a set of 5 and up to 7 IP packet =
attributes:

=20

- IP source address

- IP destination address

- Source port

- Destination port

- Layer 3 protocol type

- Class of Service

- Router or switch interface

=20

Although, there is a lot more support with Netflow version 9:

Thanks Omar.

=20

To answer your question, first let me point out to other readers that =
the two entries that Omar is quoting here exist as values in an =
enumeration called EventTypeEnum which as its name implies contains a =
list of different labels for grouping types (or classes) of events to be =
used as low-granularity buckets for characterizing and classifying =
events.

Other entries in this enumeration include things like =E2=80=9CFile Ops =
(CRUD)=E2=80=9D, =E2=80=9CProcess Mgt=E2=80=9D, =E2=80=9CAuthorization =
(ACL)=E2=80=9D, etc.

=20

The =E2=80=9CPacket Traffic=E2=80=9D value is intended to characterize =
events dealing with network packet traffic as its name implies.

The =E2=80=9CData Flow=E2=80=9D value is intended to characterize events =
dealing with forms of data flow at a higher level of abstraction than =
just packet traffic. The relationship between these two values could be =
viewed as =E2=80=9CPacket Traffic=E2=80=9D being a more detailed form of =
=E2=80=9CData Flow=E2=80=9D just as the values =E2=80=9CApp Layer =
Traffic=E2=80=9D and =E2=80=9CHTTP Layer Traffic=E2=80=9D, also in this =
enumeration, could be other levels in this same abstraction stack.

The idea behind the varying levels of abstraction is to leave  buckets =
large enough to capture a wide variety of potential event types (e.g. =
data flow events other than obvious things like packet traffic) but also =
enable the use of smaller more specific buckets when they are =
appropriate and commonly used.

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression =
(CybOX=E2=84=A2) is intended as a draft release of an initial major =
version of the CybOX Language that could be utilized for practical =
operational use and integration into other standards efforts. This =
release consists of three primary components: a pair of formal language =
specifications for the core language content and defined objects =
content, a set of language implementation XML schemas (core, =
common_types, and ~70 defined object schemas), and a small initial set =
of language utilities including an initial draft Snort->CybOX transform, =
an initial draft OpenIOC->CybOX transform and a set of CybOX language =
Python bindings. Recognizing that this is the first time that the formal =
language specifications will be available for review and as such will =
likely generate feedback from new stakeholders, this initial major =
version is being released as a =E2=80=9Cdraft=E2=80=9D v1.0 with the =
expectation of cycles of new feedback and revision before a =
=E2=80=9Cfinal=E2=80=9D v1.0 is released.

The CybOX v1.0 (Draft) XML schemas include a significant number of =
changes from v0.7 to improve:

=C2=B7       Clarity, documentation, and descriptive formality for =
reference and implementation by other standards and users.

=C2=B7       Consistency, simplicity, and efficiency.

=C2=B7       Alignment (as appropriate) to existing normative =
references.

=C2=B7       Expressiveness of the schema to better support the broad =
set of use cases it targets (malware characterization, indicator and =
incident data sharing, event management, etc.) including the addition of =
an initial set of network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

=C2=B7        Refinement of namespaces and schema locations for better =
effectiveness and flexibility going forward.

=C2=B7        Normalized all content according to an established set of =
naming conventions.

=C2=B7        Fully annotated all language items (types, attributes, =
elements, etc.).

=C2=B7        Moved several commonly leveraged types out of the core =
schema and into common_types.

=C2=B7        Achieved full typing of entire schema structure such that =
all attributes and elements are definitively typed.

=C2=B7        Changed all identifiers from ID and IDREF types to be =
QNames enabling globally unique identifiers and flexibility for =
domain-specific users of CybOX to define their own identifier syntax =
locally.

=C2=B7        Reordered attributes and elements in numerous types to =
better reflect common usage and priority.

=C2=B7        Added major_version and minor_version attributes for core =
schema.

=C2=B7        Added capability to characterize source of overall =
observable package data and for individual observables.

=C2=B7        Modified the logical composition structure such that any =
such compositions are now contained within a Observable_Composition =
element providing improved simplicity and modularity.

=C2=B7        Removed the Delta element from ObservableType and =
relocated the appropriate portions (Change, Trend, and Frequency) to =
appropriate locations under Stateful_Measure and Event.

=C2=B7        Added a Domain_Specific_Object_Attributes field to Object =
utilizing an abstract type that will allow domain-specific use cases to =
add in their own domain-specific attributes for Objects.

=C2=B7        Added a Tool-Specific_Data field to ToolInformationType =
utilizing an abstract type that will allow addition of tool-specific =
data.

=C2=B7        Added an Indicators field to MeasureSourceType utilizing =
an abstract type that will allow characterizing differing formats or =
standards of indicators that may have led to the identification of the =
observable data.

=C2=B7        Enhanced the Hash structure to capture full fuzzy hashes =
in addition to simple hashes

=C2=B7        Added a new ExtractedFeaturesType that can be used to =
adorn differing objects (e.g., files, memory, etc.) to capture extracted =
strings, imports, functions and code snippets

=C2=B7        Added a ByteRunsType to enable capture of byte runs within =
various objects.

=C2=B7        Added object_reference attribute to DefinedObjectType to =
better support referencing of independently defined Objects from within =
another Object definition.

=C2=B7        Added a generic DataSegmentType to provide a relatively =
abstract way of characterizing data segments that may be =
written/read/transmitted or otherwise utilized in actions or defined in =
objects.

=C2=B7        Added several new defined object schemas (API, Code, =
Device, DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry, =
Network_Subnet, Unix_Network_Route_Entry) including an initial set of =
network-centric defined objects.

=C2=B7        Modified every defined object schema with added =
annotations as well as minor and in some cases substantive changes to =
fix errors, improve consistency and alignment with existing normative =
references, and to improve expressiveness in support of the targeted use =
cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema, =
common_types and the defined object schemas is too great to list every =
change in these release notes. Detailed difference reports are available =

Mike,

If you always utilized the most abstract label (Data Flow) to adorn =
events even when you knew the more specific type that they were and had =
a more specific label for them, then yes you would lose distinction.

Such misuse is always the potential downside of enabling flexibility =
through abstraction.

If you know that the event you are characterizing has to do with Packet =
Traffic and not just some form of more general data flow that does not =
have an appropriate associated event type label, then you should =
absolutely use Packet Traffic and not Data Flow. An event should only be =
tagged with an abstract label like Data Flow if there is not an =
appropriate more concrete label available.

=20

In answer to your second question, yes Data Flow definitely covers not =
only network-related events but also events that have nothing to do with =
the wire.

My response to Tom Millar that I sent at 12:52am this morning lists out =
several non-network related types of events that Data Flow could apply =
to.

=20

Please do not feel bad for asking these questions. They help you =
understand our approach, they help others understand our approach, they =
help us better understand the perspective of the communities we are =
targeting to support, they help us uncover issues with our approach or =
implementation, and they help us understand where we need to explain =
ourselves better.

=20

Thank you for the constructive discourse.

Sean,

What you say makes sense.  But, if you will bear with me.  (Still =
learning this.)

=20

If one used Packet Traffic event type always instead of Data Flow event =
type, would some distinction be lost?

Or, put another way, since the packet stuff seems to cover most =
network-based events, does Data Flow involve something that is not on =
the wire?

(Such as an inter-process communication that doesn=E2=80=99t go through =
a protocol stack.)

Mike,

=20

Just to clarify, all of our discussion so far about =E2=80=9CData =
Flow=E2=80=9D and netflow were all in regards to an enumeration called =
EventTypeEnum that simply lets you tag a cyber observable event with a =
type label. It is metadata for an event description.

The only object we have been talking about in any detail so far was the =
Network_Flow object. These two topics are totally independent of each =
other. There is no Data_Flow object.

The abstraction overlap we have been discussing is only in the metadata =
tag applied to an event to characterize what type/class of event it is.

=20

The defined objects themselves (including Network_Flow) have been =
designed to avoid, as much as possible, overlap of the type you =
describe.

The approach we have taken is that where there is common structure and =
meaning relevant to multiple different types of objects, the structure =
for that commonality is broken out into its own object (e.g. Address, =
URI, Port, Account, Process, etc.).

Content based on this common object structure can be embedded within a =
leveraging object (via direct use of the object type) if the content is =
directly relevant only within the context of that object or as an =
independent object and associated to any number of other objects to =
which it is relevant utilizing relationships.

We make no guarantees that we have managed to implement this approach =
flawlessly but we believe that it yields a good balance of consistency, =
efficiency and flexibility. It also allows easy modular use of only what =
is relevant within a given context and enables extension and evolution =
to easily occur in a localized fashion rather than having to extend and =
modify one monolithic structure standard.

=20

Does that make sense?

=20

Sean,

=20

Does the overlap between the various objects present a problem?

=20

If there are one or more objects that could carry the same data, then =
human nature means that probability-wise someone will choose data flow =
instead of Netflow.

That is the underlying principle in Murphy=E2=80=99s Law, where you try =
to design it so that there is only one way to do it, and thus private =
Murphy won=E2=80=99t do it the =E2=80=9Cwrong=E2=80=9D way.

=20

Just wondering if these should be mutually exclusive sets.  And designed =
as such.

Might improve interoperability.  (And avoid discussions like this in =
future.)  J

=E2=80=9Cupper layer=E2=80=9D? Yes, as in higher abstraction.

Just =E2=80=9Cprotocols=E2=80=9D? No.

=20

You guys have been looking at this through the lens of network flow =
which if fine for thinking about that perspective but it is important to =
also realize that the EventTypeEnum and its =E2=80=9CData Flow=E2=80=9D =
value go far beyond network-related scope.

It is about a lot of other types of potential data flows (as I just =
outlined in a response to Tom) that have nothing to do with network =
flow.

=20

Thanks for your response though. This is the kind of discussions that we =
hope to have a lot more of among the various supported communities.

=20

=20

BTW, you may have noticed that the Network_Flow object within CybOX v1.0 =
(Draft) supports expression of netflow within several of the most common =
formats including Netflow9 (as well as IPFIX as Luis pointed out, =
Netflow5 and SiLK as well as bi-directional flow in YAF). The common =
5-tuple or 7-tuple (you describe) (in our case it is an 8-tuple as we =
broke the router interface out into both ingress and egress J) shared by =
pretty much all of the netflow approaches has been broken out into a =
shared Network_Flow_Label structure. The various context-dependent =
portions of the independent approaches are then captured within optional =
structures dedicated to each of them. We hope that eventually the =
community can work to come together towards a single overall common =
expressive structure for netflow that meets the needs of all. We hope =
that CybOX and its use can even help that sort of maturation and =
normalization. But since no such universal structure exists today, we =
decided to enable optional expression of the most common individual =
formats within a single netflow object to serve the large majority of =
relevant users, maintain flexibility and enable discussions and analysis =
of netflow within a common package.

We look forward to continuing discussions with the community to validate =
or invalidate this approach and to refine and mature going forward.

I believe that what Sean is saying is that =E2=80=9Cdata flow=E2=80=9D =
is just a value that is meant for upper layer protocols. But, you have a =
good point. Traditionally, a =E2=80=9Cflow=E2=80=9D in =
=E2=80=9CNetflow=E2=80=9D is based on a set of 5 and up to 7 IP packet =
attributes:

=20

- IP source address

- IP destination address

- Source port

- Destination port

- Layer 3 protocol type

- Class of Service

- Router or switch interface

=20

Although, there is a lot more support with Netflow version 9:

Thanks Omar.

=20

To answer your question, first let me point out to other readers that =
the two entries that Omar is quoting here exist as values in an =
enumeration called EventTypeEnum which as its name implies contains a =
list of different labels for grouping types (or classes) of events to be =
used as low-granularity buckets for characterizing and classifying =
events.

Other entries in this enumeration include things like =E2=80=9CFile Ops =
(CRUD)=E2=80=9D, =E2=80=9CProcess Mgt=E2=80=9D, =E2=80=9CAuthorization =
(ACL)=E2=80=9D, etc.

=20

The =E2=80=9CPacket Traffic=E2=80=9D value is intended to characterize =
events dealing with network packet traffic as its name implies.

The =E2=80=9CData Flow=E2=80=9D value is intended to characterize events =
dealing with forms of data flow at a higher level of abstraction than =
just packet traffic. The relationship between these two values could be =
viewed as =E2=80=9CPacket Traffic=E2=80=9D being a more detailed form of =
=E2=80=9CData Flow=E2=80=9D just as the values =E2=80=9CApp Layer =
Traffic=E2=80=9D and =E2=80=9CHTTP Layer Traffic=E2=80=9D, also in this =
enumeration, could be other levels in this same abstraction stack.

The idea behind the varying levels of abstraction is to leave  buckets =
large enough to capture a wide variety of potential event types (e.g. =
data flow events other than obvious things like packet traffic) but also =
enable the use of smaller more specific buckets when they are =
appropriate and commonly used.

=20

Does this make sense?=20

I echo Luis=E2=80=99 comments. It is good to see the inclusion of =
network objects. Quick question to the team related to your netflow =
comment.

I am looking at:

http://cybox.mitre.org/XMLSchema/cybox_core_v1.0%28draft%29.xsd

=E2=80=A6 and it looks that we renamed it to =E2=80=9CData =

Hey everyone,

I just wanted to let you all know that CybOX v1.0 (Draft) content is now =
live on the website. http://cybox.mitre.org

The release notes are provided inline below.

The key items of note are:

=C2=B7        The release of two formal specifications for the CybOX =
language (one for the core language and one for the defined objects)

=C2=B7        The XML Schema has gone through extensive improvements for =
expressiveness, clarity, consistency, efficiency, alignment to existing =
normative references and documentation.

=C2=B7        This release includes an initial set of language =
utilities: a draft Snort -> CybOX transform, a draft OpenIOC -> CybOX =
transform, and a set of Python bindings for the CybOX language.

=C2=B7        The website now includes a small set of content examples. =
This set will grow going forward.

This release involved a lot of hard work from a diverse group of people. =
Thank you all for your contributions and effort. We could not have done =
it without you.

We look forward to everyone=E2=80=99s feedback and collaboration as we =
continue to improve and mature the CybOX language.

CybOX v1.0 (Draft) Release Notes

The Version 1.0 (Draft) release of Cyber Observable eXpression =
(CybOX=E2=84=A2) is intended as a draft release of an initial major =
version of the CybOX Language that could be utilized for practical =
operational use and integration into other standards efforts. This =
release consists of three primary components: a pair of formal language =
specifications for the core language content and defined objects =
content, a set of language implementation XML schemas (core, =
common_types, and ~70 defined object schemas), and a small initial set =
of language utilities including an initial draft Snort->CybOX transform, =
an initial draft OpenIOC->CybOX transform and a set of CybOX language =
Python bindings. Recognizing that this is the first time that the formal =
language specifications will be available for review and as such will =
likely generate feedback from new stakeholders, this initial major =
version is being released as a =E2=80=9Cdraft=E2=80=9D v1.0 with the =
expectation of cycles of new feedback and revision before a =
=E2=80=9Cfinal=E2=80=9D v1.0 is released.

The CybOX v1.0 (Draft) XML schemas include a significant number of =
changes from v0.7 to improve:

=C2=B7       Clarity, documentation, and descriptive formality for =
reference and implementation by other standards and users.

=C2=B7       Consistency, simplicity, and efficiency.

=C2=B7       Alignment (as appropriate) to existing normative =
references.

=C2=B7       Expressiveness of the schema to better support the broad =
set of use cases it targets (malware characterization, indicator and =
incident data sharing, event management, etc.) including the addition of =
an initial set of network-related defined objects.

Summary of changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

=C2=B7        Refinement of namespaces and schema locations for better =
effectiveness and flexibility going forward.

=C2=B7        Normalized all content according to an established set of =
naming conventions.

=C2=B7        Fully annotated all language items (types, attributes, =
elements, etc.).

=C2=B7        Moved several commonly leveraged types out of the core =
schema and into common_types.

=C2=B7        Achieved full typing of entire schema structure such that =
all attributes and elements are definitively typed.

=C2=B7        Changed all identifiers from ID and IDREF types to be =
QNames enabling globally unique identifiers and flexibility for =
domain-specific users of CybOX to define their own identifier syntax =
locally.

=C2=B7        Reordered attributes and elements in numerous types to =
better reflect common usage and priority.

=C2=B7        Added major_version and minor_version attributes for core =
schema.

=C2=B7        Added capability to characterize source of overall =
observable package data and for individual observables.

=C2=B7        Modified the logical composition structure such that any =
such compositions are now contained within a Observable_Composition =
element providing improved simplicity and modularity.

=C2=B7        Removed the Delta element from ObservableType and =
relocated the appropriate portions (Change, Trend, and Frequency) to =
appropriate locations under Stateful_Measure and Event.

=C2=B7        Added a Domain_Specific_Object_Attributes field to Object =
utilizing an abstract type that will allow domain-specific use cases to =
add in their own domain-specific attributes for Objects.

=C2=B7        Added a Tool-Specific_Data field to ToolInformationType =
utilizing an abstract type that will allow addition of tool-specific =
data.

=C2=B7        Added an Indicators field to MeasureSourceType utilizing =
an abstract type that will allow characterizing differing formats or =
standards of indicators that may have led to the identification of the =
observable data.

=C2=B7        Enhanced the Hash structure to capture full fuzzy hashes =
in addition to simple hashes

=C2=B7        Added a new ExtractedFeaturesType that can be used to =
adorn differing objects (e.g., files, memory, etc.) to capture extracted =
strings, imports, functions and code snippets

=C2=B7        Added a ByteRunsType to enable capture of byte runs within =
various objects.

=C2=B7        Added object_reference attribute to DefinedObjectType to =
better support referencing of independently defined Objects from within =
another Object definition.

=C2=B7        Added a generic DataSegmentType to provide a relatively =
abstract way of characterizing data segments that may be =
written/read/transmitted or otherwise utilized in actions or defined in =
objects.

=C2=B7        Added several new defined object schemas (API, Code, =
Device, DNS_Record, Network_Flow, Network_Packet, Network_Route_Entry, =
Network_Subnet, Unix_Network_Route_Entry) including an initial set of =
network-centric defined objects.

=C2=B7        Modified every defined object schema with added =
annotations as well as minor and in some cases substantive changes to =
fix errors, improve consistency and alignment with existing normative =
references, and to improve expressiveness in support of the targeted use =
cases.

Detailed changes from CybOX_v0.7 to CybOX_v1.0_(Draft):

The level of changes within v1.0 (Draft) in the core schema, =
common_types and the defined object schemas is too great to list every =
change in these release notes. Detailed difference reports are available =
for each individual schema at: =

All:

A bit of time has passed since David sent out the most recent introductory
document, and there does not seem to be much activity with respect to the
structure of this document.  Should we assume that silence is, in effect,
agreement to the abstract and skeleton format?

I would also like to see some discussion about the charter happen on this
list.  It seems reasonable to start thinking about how we move the charter
forward even though we may not have the complete use case document yet.

Regards,

Adam

All I'm saying is that CIM is already widely used for exactly the 
purposes and use-cases specified by AI.  From what I can determine, AI 
is not inherently capable of dealing with issues like reconciliation, 
but there are existing well-known practices around CIM.  If CIM's 
attributes are insufficient for our needs, it is extensible by design.  
But I think the CIM class model is more than sufficient for anything we 
can dream up.

If every potential user designs a new standard, then there are, in 
effect, no standards.  My opinion is that since we can choose between an 
immature proposal (AI), and a mature widely-adopted standard (CIM), the 
choice should be obvious.

Anyway, are Tim and I the only people with thoughts on the matter?  I 
was hoping that perhaps David Waltermire might be able to explain the 
rationale behind proposing a new standard.

--David Solin

    All I'm saying is that CIM is already widely used for exactly the
    purposes and use-cases specified by AI.&nbsp; From what I can determine,
    AI is not inherently capable of dealing with issues like
    reconciliation, but there are existing well-known practices around
    CIM.&nbsp; If CIM's attributes are insufficient for our needs, it is
    extensible by design.&nbsp; But I think the CIM class model is more than
    sufficient for anything we can dream up.<br>
    <br>
    If every potential user designs a new standard, then there are, in
    effect, no standards.&nbsp; My opinion is that since we can choose
    between an immature proposal (AI), and a mature widely-adopted
    standard (CIM), the choice should be obvious.<br>
    <br>
    Anyway, are Tim and I the only people with thoughts on the matter?&nbsp;
    I was hoping that perhaps David Waltermire might be able to explain
    the rationale behind proposing a new standard.<br>

        <p class="MsoNormal">Hi Tim,<br>
          <br>
          Addressing the problem of uniqueness certainly does not
          require an entirely new data model.&nbsp; Existing CMDBs have to
          solve the problem of multiple discovery sources, as each
          product interacting with it is potentially another discovery
          source.&nbsp; BMC's Atrium CMDB, for instance, extends the CIM
          schema with a reconciliation ID that is used for this purpose,
          and I imagine that's probably not an uncommon solution.&nbsp;
          There's no reason we can't have an Asset Identification
          specification that consists purely of an extension of CIM --
          where we can add, for instance, a CPE property to existing
          classes (e.g., OperatingSystem, DatabaseSystem ... or perhaps
          just to the System parent class?).&nbsp; Indeed, perhaps that's
          what you're suggesting?<br>
          <br>
          To my eye, the AI specification looks largely like a subset of
          CIM, except with the addition of the specialized ai:website
          object (which feels like it should be unnecessary).&nbsp; Why do we
          want to reinvent the wheel?<br>
          <br>
          Regards,<br>
          --David<br>

            metadata in AI is designed with the other SCAP metadata in
            mind whereas CIM was not and while they may share common
            keys like IP address to perform a join, more and more this
            is not a stable characteristic of the asset in either
            domain.&nbsp; Another consideration here is that CIM would not
            have in it something like a CPE identifier, very common key
            for synthesis across domains within the SCAP family.&nbsp; My
            suggestion here is that we not look for a single domain to
            identify an asset but to ensure that all the data domains
            (AI, CIM, etc) have in them enough boundary objects to
            &#8220;join&#8221; or synthesize multiple domains.&nbsp; We should ensure
            that all information domains have in it a rich set of stable
            characteristics that afford syntactical matching of the
            metadata for the purposes of Inter-domain multi-sensor data

            automated scanning comes in at least two flavors,
            authenticated-scanning and unauthenticated-scanning.&nbsp; We
            must keep this in mind as we look to the design or borrow
            these metadata formats (AI, CIM, etc).&nbsp; Most if not all CMDB
            assumes the old network management mindset of
            nodes-under-management and node-not-under-management.&nbsp; The
            former having an agent installed or some
            authentication/authorization provided, the latter assumes an
            assessment of the target via its target surface in an
            unauthenticated manner.&nbsp; I raise this issue once again
            because OVAL for example makes no provision for the
            assessment to take place in an unauthenticated manner.&nbsp;&nbsp; We
            need to keep this in mind as we look to populate the
            metadata of AI as certain fields will only be valid for
            authenticated scanning or an agent.&nbsp; I&#8217;m a vendor that has
            both types of scanners and I must say that for reasons I
            will not get into here, customers deploy unauthenticated
            scanners across their entire enterprise and authenticated
            scanners in targeted scopes.&nbsp; I raise this issue because
            time and time again, customers come back to us with the
            unauthenticated scanners having much more identification of
            end-point assets than any other authenticated scanner.&nbsp; This
            is a sidebar but I wanted to share this experience having
            been a supplier of this technology for the past 12 years.&nbsp;

          <br>
          Was there any discussion at the meeting in Paris on Asset
          Identification vs. CIM, or has anyone identified a use-case
          for AI for which CIM is not appropriate?&nbsp; For the sake of
          making SACM easily adoptable by large enterprises with
          existing CMDB implementations, I strongly advocate abandoning
          AI in favor of CIM.&nbsp; I'd be happy to discuss how BMC, IBM, HP,
          CA, etc. have been making CIM the centerpiece of their systems
          management offerings for most of the past decade.<br>

Ok.  I'll bite. ;-)  First off, I am not interested in creating a new stand=
ard that competes with CIM or any of the other data models capturing asset =
information.  If fact, if there is a better solution I'd like to explore it=
.  This thread has been useful in exploring some possibilities.

Speaking to Asset Identification, one of the major reasons we created the s=
pecification was to provide a mapping mechanism that can synthesize data ac=
ross any underlying systems management protocol (e.g. WEBM, SNMP, NetConf, =
etc) and data format (e.g. CIM, MIB, Yang, SCAP, etc.)  We wanted something=
 that would be information domain neutral.  In my mind the controlled vocab=
ulary approach used in Asset Identification provides part of a semantic abs=
traction over all of these things.  It enables data synthesis within a hete=
rogeneous environment of tools implementing a variety of standards-based ap=
proaches.

I hope this provides more context.

Sincerely,
Dave

All I'm saying is that CIM is already widely used for exactly the purposes =
and use-cases specified by AI.  From what I can determine, AI is not inhere=
ntly capable of dealing with issues like reconciliation, but there are exis=
ting well-known practices around CIM.  If CIM's attributes are insufficient=
 for our needs, it is extensible by design.  But I think the CIM class mode=
l is more than sufficient for anything we can dream up.

If every potential user designs a new standard, then there are, in effect, =
no standards.  My opinion is that since we can choose between an immature p=
roposal (AI), and a mature widely-adopted standard (CIM), the choice should=
 be obvious.

Anyway, are Tim and I the only people with thoughts on the matter?  I was h=
oping that perhaps David Waltermire might be able to explain the rationale =
behind proposing a new standard.

And you are so right in that CIM would require more schema to aid in the ta=

What I am sensitive to here is the administrative realms and political real=

one is impaired by the others progress or dormancy, bad design, no donut.

Hi Tim,

Addressing the problem of uniqueness certainly does not require an entirely=
 new data model.  Existing CMDBs have to solve the problem of multiple disc=
overy sources, as each product interacting with it is potentially another d=
iscovery source.  BMC's Atrium CMDB, for instance, extends the CIM schema w=
ith a reconciliation ID that is used for this purpose, and I imagine that's=
 probably not an uncommon solution.  There's no reason we can't have an Ass=
et Identification specification that consists purely of an extension of CIM=
 -- where we can add, for instance, a CPE property to existing classes (e.g=
., OperatingSystem, DatabaseSystem ... or perhaps just to the System parent=
 class?).  Indeed, perhaps that's what you're suggesting?

To my eye, the AI specification looks largely like a subset of CIM, except =
with the addition of the specialized ai:website object (which feels like it=
 should be unnecessary).  Why do we want to reinvent the wheel?

Regards,
--David

There are at least two considerations:

Inter-domain multi-sensor data fusion and synthesis
This is for all practical purposes the inverse-functional-property or prima=
ry key syntax match problem.
The metadata in AI is designed with the other SCAP metadata in mind whereas=
 CIM was not and while they may share common keys like IP address to perfor=

 either domain.  Another consideration here is that CIM would not have in i=

ning and unauthenticated-scanning.  We must keep this in mind as we look to=
 the design or borrow these metadata formats (AI, CIM, etc).  Most if not a=
ll CMDB assumes the old network management mindset of nodes-under-managemen=
t and node-not-under-management.  The former having an agent installed or s=
ome authentication/authorization provided, the latter assumes an assessment=
 of the target via its target surface in an unauthenticated manner.  I rais=
e this issue once again because OVAL for example makes no provision for the=
 assessment to take place in an unauthenticated manner.   We need to keep t=
his in mind as we look to populate the metadata of AI as certain fields wil=
l only be valid for authenticated scanning or an agent.  I'm a vendor that =
has both types of scanners and I must say that for reasons I will not get i=
nto here, customers deploy unauthenticated scanners across their entire ent=
erprise and authenticated scanners in targeted scopes.  I raise this issue =
because time and time again, customers come back to us with the unauthentic=
ated scanners having much more identification of end-point assets than any =
other authenticated scanner.  This is a sidebar but I wanted to share this =
experience having been a supplier of this technology for the past 12 years.

That is very neat, but I also have a question on the original topic...

Was there any discussion at the meeting in Paris on Asset Identification vs=
. CIM, or has anyone identified a use-case for AI for which CIM is not appr=
opriate?  For the sake of making SACM easily adoptable by large enterprises=
 with existing CMDB implementations, I strongly advocate abandoning AI in f=
avor of CIM.  I'd be happy to discuss how BMC, IBM, HP, CA, etc. have been =
making CIM the centerpiece of their systems management offerings for most o=
f the past decade.

I can take a stab at that.  It will be useful at minimum to start some
discussion.

Hi Dave,

Thanks for sending this out.  I like the abstract and the structure of

the document so far, so no further comments from me on the abstract.
Are you planning to create a first pass at a complete list of use
cases for the document?

Hi list,

I finished the translation into french of all available CWEs (Titles +
Descriptions).
We use it for our CERT.
I should soon share this work with french CERTs, but I would like to
know if others could provide a translation in other languages?
(I know some spain guys are working on it)

Thanks
My 5 euro cents
