Hi, I have been selected as the Routing Directorate QA reviewer for this draft. Document: draft-ietf-i2rs-protocol-security-requirements-04.txt Reviewer: Tomonori Takeda Review Date: May 20, 2016 Intended Status: Standards Track I am not following I2RS work closely, but in the spirit of QA review, this is OK in my understanding. https://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDirDocQa Here are my comments. I think it is very important to have documents dedicated for security for new protocols such as I2RS protocols. Overall, I think the document is well organized and clear what are security requirements for I2RS. Some specific comments. 1) The document is intended to be Standards Track. I do not think it is common for requirement drafts to be Standards Track. 2) In Section 3.1, requirements are mentioned that are set in draft-ietf-i2rs-architecture-15. Some of these requirements are not directly mentioned in draft-ietf-i2rs-architecture-15, but rather implied. For example, draft-ietf-i2rs-architecture-15 mentions identifier for I2RS client, but does not mention identifier for I2RS agent (IMO). Please note that I think requirements mentioned in Section 3.1. makes sense and valid. I am just commenting on the way of writing. 3) I think there is dependency on requirements mentioned in this document. Specifically, if mutual authentication (Section 3.1), secure transport (Section 3.2), and role-based security (Section 3.3) are met, confidentiality (Section 3.3) and integrity (Section 3.4) can be achieved (expect SEC-REQ-16: traceability requirement). Perhaps, it depends on in which aspects security requirements should be written (in terms of mechanisms or in terms of features). Again, I am just commenting on the way of writing. 4) This is just an edit, but in page.10, "Requirements SEC-REQ-13 and SEC-REQ-14" should be "Requirements SEC-REQ-14 and SEC-REQ-15". Thanks, Tomonori Takeda
