IETF Last Call Review of draft-ietf-intarea-proxy-config-11
review-ietf-intarea-proxy-config-11-secdir-lc-lonvick-2026-03-22-00

Hi,

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. The summary of the review is Ready with Issues.

I agree with the GENART review that the authors appear to be deeply involved in
the subject and have provided a comprehensive document, which just isn't easy
to read.

I also believe that the document may be improved by providing a threat model
and some verbiage of how to address the threats. Guidance may be found in BCP
72 (RFC 3552). For instance, I'm not seeing how this is not susceptible to a
man-in-the-middle attack, or a resource exhaustion attack. I'm not familiar
with the subject matter so they may be in there and I'm just not seeing them.

Best regards,
Chris
