This draft is a work item of the Service Function Chaining WG of the IETF. Title : Proof of Transit Authors : Frank Brockners Shwetha Bhandari Tal Mizrahi Sashank Dara Stephen Youell Filename : draft-ietf-sfc-proof-of-transit-07.txt Pages : 31 Date : 2020-10-25 Abstract: Several technologies such as Traffic Engineering (TE), Service Function Chaining (SFC), and policy based routing are used to steer traffic through a specific, user-defined path. This document defines mechanisms to securely prove that traffic transited a defined path. These mechanisms allow to securely verify whether, within a given path, all packets traversed all the nodes that they are supposed to visit. The document defines the data model through Unified Modeling Language (UML) class diagrams and formally specifies it using an NDMA- compliant YANG model to enable these mechanisms. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-sfc-proof-of-transit/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-sfc-proof-of-transit-07 https://datatracker.ietf.org/doc/html/draft-ietf-sfc-proof-of-transit-07 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-sfc-proof-of-transit-07 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

List-Help: List-Subscribe: , X-List-Received-Date: Mon, 26 Oct 2020 22:25:25 -0000 Reviewer: Robert Sparks Review result: Has Nits I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. This document has nits that should be addressed before publication as Proposed Standard RFC. Document reviewed: draft-ietf-sfc-serviceid-header-10 This document's security considerations rest on the premise that the information it discusses will be added, transported, consumed, and removed within a single administrative domain that is protected from eavesdroppers and malicious on-path attackers through administrative controls. It is quite upfront about that assumption, and the sfc documents it relies on make the same assertions. This document introduces a mechanism that intentionally allows identifiers (addresses) that would normally be hidden/contained behind a nat to be shared beyond that nat, but again, within that single administrative domain. NITS: There are many places where the language in the document needs to be simplified. There are also many places where 2119 language is being used in a way that does not make sense. In document order: Introduction paragraph 2, sentence 1. What does it mean to infer enforcement? Perhaps you mean "policies can be inferred"? Please simplify this sentence. Break the example into a separate sentence and add detail if you can. If possible, provide a reference to what you mean by "SFC-based differentiated traffic policies" means. Introduction paragraph 3. This whole paragraph has complicated, paragraph separated, phrases that should be written more simply. The next to last sentence (at 53 words) is particularly hard to follow. Introduction paragraph 4, last sentence. This sentence does not parse. Please rework it. Introduction paragraph 5. This one sentence paragraph was the most difficult in the document for me to read. Please break it into several simpler sentences. Section 3: at "In order to prevent interoperability issues, the data and their format to be injected in such header SHOULD be configured to nodes authorized to inject such headers." This is not a 2119 SHOULD. It's even not clear what "the data" is here. I suggest something like "The identifiers carried in the Context Headers are opaque. Nodes providing them and consuming them will be configured with the necessary information needed see into them." Section 3, at "Failures to inject such headers SHOULD be logged locally while a notification alarm MAY be sent to a Control Element. The details of sending notification alarms (i.e., the parameters affecting the transmission of the notification alarms depend on the information in the Context Header such as frequency, thresholds, and content of the alarm (full header, timestamp, etc.)) SHOULD be configurable." None of these are correct use of 2119. Consider re-framing the paragraph without using these terms. Section 3 at "That is, to strip such Context Headers." is not a sentence. Section 3 at the paragraph beginning "Depending on local policy". The structure of this paragraph is very odd. Doesn't base SFC say to preserve NSH at intermediaries? I suggest replacing this paragraph with something like "Normal SFC intermediary behavior preserves Network Service Headers. Local policy can require a proxy to strip ..." Section 3 at "NSH-aware SFs MUST be capable to run additional validation checks". This isn't 2119. Perhaps you mean to say "Be aware that local policies may require running additional validation checks at NSH-aware SFs". The whole paragraph can be simplified. Section 3 at "Multiple Subscriber Identifier Context Headers MAY be present in the NSH, each carrying a distinct opaque value but all pointing to the same subscriber." This is a place where a 2119 MUST _would_ make sense. Say "Such multiple headers MUST identify the same subscriber". I wonder, though, if you're closing a door on carrying multiple identities that you'll regret later. Section 4 first paragraph, first sentence: I suggest replacing "identifier is" with "identifiers are" Section 4 fifth paragraph: "defined as optional" -> "defined as an optional" Section 4 sixth paragraph. Similar to the section 3 paragraph I point to above, the structure here is very odd. Again, I suggest something like "Normal SFC intermediaries will preserve Context Headers, but local policy may require a proxy to to strip one after processing it." Section 4 seventh paragraph: "ocnlficting"->"conflicting". I assume the default behavior described here is specified in the base NSH docs? Security Considerations section paragraph 4: Consider "logging the content of ... is not advised" rather than using 2119 here. The paragraph would be better formulated if it explained the risk - SFs that _did_ use the context might be better off not logging them in many cases as well.

List-Subscribe: , X-List-Received-Date: Wed, 28 Oct 2020 14:27:42 -0000 Thanks Med - This sufficiently addresses my comments. Thanks for adding clarity with=20 the edits. I do want to ask again, though, whether you're closing off an=20 opportunity with the requirement that all the identifiers belong to a=20 single subscriber, and that the group made that choice explicitly rather = than just falling into it. I could see an alternative that looked like "allow multiple identities,=20 and the use of them in inferred policies is 'is any of' ". Stretching a=20 little into slightly different problem domains, consider, for example,=20 the doctor that could be using his own phone number or the office phone=20 number. I'm not suggesting that allowing such multiple identities is the right=20 thing to do, but I want to verify that simple alternatives like that=20 were considered and rejected, and that you have a way to do them in the=20 future if you want. The text does imply that the group looked at the general problem of=20 trying to capture arbitrary relationships between multiple identities,=20 and decided not to solve that. If that's how it happened, you might=20 consider explicitly saying that so future related work isn't guessing or = making assumptions about the motivation here.

position for draft-ietf-sfc-serviceid-header-11: No Objection When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-sfc-serviceid-header/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- I found this to be hard to read, despite its short length. I hope my comments below can help with that. — Abstract — This document defines Subscriber and Performance Policy Identifiers Network Service Header Variable-Length Context Headers to inform That string of capitalized words really is indecipherable. I think that’s because it’s talking about three separate things (Identifiers, Network Service Headers, and Context Headers) with nothing to separate them. Can you reword the sentence to fix that? Maybe, “This document defines Subscriber and Performance Policy Identifiers that can be put into variable-length Context Headers within the Network Service Header to inform...”? — Section 1 — NAT functionality can reside in a distinct node which for 3GPP network can be the Packet Data Network (PDN) Gateway (PGW) as specified in [TS23401] in case of 4G or the User Plane Function (UPF) facing the external Data Network (DN) [TS23501] in case of 5G, respectively. That’s a long sentence with at least one grammatical error, and it’s hard to read. May I suggest splitting it?: NEW NAT functionality can reside in a distinct node. For a 4G 3GPP network, that node can be the Packet Data Network (PDN) Gateway (PGW) as specified in [TS23401]. For a 5G 3GPP network it can be the User Plane Function (UPF) facing the external Data Network (DN) [TS23501]. END This approach avoids to require additional internal structures of the Context Headers You can’t “avoid to require”. You can say that the approach “avoids the requirement of additional...”, or, better, simply “avoids additional...”. — Section 3 — In order to prevent interoperability issues, the type the identifiers carried in the Subscriber Identifier Context Headers and their format to be injected in such header should be configured to nodes authorized to inject and consume such headers. I can’t parse that sentence, and I can’t suggest a fix because I have no idea what it’s trying to say. I don’t know whether the issue is grammar or difficult wording. Can you please fix it? Local policies may require running additional validation checks on the content of these Context Headers (e.g., accept only some lengths, types) and the behavior to adopt at NSH-aware SFs. You lose me here at “and the behavior”: I don’t see how it’s supposed to connect to the rest of the sentence. Are you trying to say that: 1. Local policies may require running validation checks, and 2. Local policies may define the behavior to adopt ? Or is it something else? However, this specification does not require nor preclude such NSH-aware SFs may be instructed to ignore the Context Header This also doesn’t parse. I think you can fix this by adding “that” after “preclude“. — Section 4 — Dedicated service-specific performance identifiers are defined to differentiate between services requiring specific treatment to exhibit a performance characterized by, e.g., ultra-low latency (ULL) or ultra-high reliability (UHR). Another sentence I can’t make sense of. Can you please re-word it? adapted dynamically by on-the move SFC path and SF instance Nit: you need one more hyphen, “on-the-move”. Multiple Performance Policy Identifier Context Headers MAY be present in the NSH; each carrying an opaque value Nit: change the semicolon to a comma. o Performance Policy Identifier: Represents an opaque value pointing to specific performance policy to be enforced. The structure and semantic of this field is deployment-specific. Nit: “semantics” as a noun is always used in plural form. — Section 6 — Access to subscriber data usually requires specific access privilege levels. To avoid bypassing this guard, it is not advised that an SF maintaining logs for operational reasons to also log the content of Subscriber and Performance Policy Context Headers received in NSH packets if the SF does not use the content of that header for its operation. The second sentence has some grammatical errors and is hard to read, partly because of a chain of negatives (avoid bypassing, not advised, does not use). Please reword this to say things more directly. Maybe something like this?: NEW Access to subscriber data usually requires specific access privilege levels. To maintain that protection, an SF keeping operational logs should not log the content of a Subscriber and Performance Policy Context Header received in an NSH packet unless the SF actually uses the content of that particular header for its operation. END (And can you also eliminate “received in an NSH packet” from that sentence? I think so.)

This draft is a work item of the Service Function Chaining WG of the IETF. Title : Service Function Chaining: Subscriber and Performance Policy Identification Variable-Length Network Service Header (NSH) Context Headers Authors : Behcet Sarikaya Dirk von Hugo Mohamed Boucadair Filename : draft-ietf-sfc-serviceid-header-12.txt Pages : 10 Date : 2020-10-30 Abstract: This document defines two Variable-Length Context Headers that can be carried in Network Service Header: Subscriber and Performance Policy Identifiers. These Context Headers are used to inform Service Functions about subscriber- and performance-related information for the sake of policy enforcement and appropriate service function chaining operations. The structure of each Context Header, their use and processing by NSH-aware nodes are described.

(Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-sfc-serviceid-header/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- This is an "early warning" discuss ballot, entered before I have done a full review of the document. As such, it is possible that the stated concern may in fact be a non-issue after closer examination, but the potential import of the concern seems to make it worth starting the discussion sooner rather than later. This document defines (among other things) a mechanism for carrying subscriber information in an NSH. RFC 8300 (NSH) notes both that: Metadata privacy and security considerations are a matter for the documents that define metadata format. and that: One useful element of providing privacy protection for sensitive metadata is described under the "SFC Encapsulation" area of the Security Considerations of [RFC7665]. Operators can and should use indirect identification for metadata deemed to be sensitive (such as personally identifying information), significantly mitigating the risk of a privacy violation. In particular, subscriber-identifying information should be handled carefully, and, in general, SHOULD be obfuscated. On the other hand, this document in its security considerations claims that: Data plane SFC-related security considerations, including privacy, are discussed in [RFC7665] and [RFC8300]. and does not seem to incorporate any discussion of the privacy and security considerations of the subscriber information metadata carried by the new format it conveys. Yes, it does note that all nodes with access to the information are part of the same trusted domain, but I do not think that is sufficient, especially given that personally identifiable information is often subject to strict compliance regimes. In short, 8300 and this document are referring to each other for privacy considerations, and the actual privacy considerations do not seem to be documented in either place. Additionally, I did not see any indication of how the subscriber-identifying information ought to be obfuscated (or an explanation of why it is okay to violate the SHOULD from 8300).
