[secdir] Secdir last call review of draft-ietf-sidrops-signed-tal-15

[Linda Dunbar via Datatracker <[e-mail]>]

Reviewer: Linda Dunbar
Review result: Has Issues

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.

Summary: This document introduces an in-band notification of Key Updates for
notifying RPs of the updates to a Trust Anchor Locator (TAL) and distribution
of TAL Data via TAK Objects.

While this in-band notification allows for more dynamic management of keys and
helps ensure RPs are aware of key rollovers, it introduces a single point of
failure.

Suggest to add some description in the Security Consideration on what happens
when the in-band mechanism is compromised.

Thank you very much,

Linda Dunbar
