Re: [secdir] SecDir review of draft-ietf-sidr-adverse-actions-03

[Steve KENT <[e-mail]>]

Brian,


I agree that "addressed" should be changed. How about "encompassed"?


I agree that suppression also applies in the context of a planned  (or emergency) cert rollover. We can add a sentence to note that expiration of a cert that was intended to be rolled over is also a potential outcome.


Thanks,


Steve

Put another way, it documents threats to the RPKI/BGPSEC PKI, in which there are unique threats to the PKI that can adversely affect Internet routing. The document is well written and internally consistent. The Security Considerations section is adequate.

The phrase “addressed by” confused me a little bit, as it implies some recommendation or remediation ― which this document does not attempt to do. This might be more clearly worded as “described by” or “included in”.

I think this is really a good suggestion.

In section 2.1, A-1.2 (Suppression), it seems that suppression could result in the CA certificate intended to be replaced to expire before an intended CA rollover operation happens due to thes suppressed replacement certificate. Perhaps it is not noted because this threat is not specific to RPKI/BGPSEC, but it could be another serious suppression affecting Internet routing.

CA rollover operation is a specific scenario where CA certificate suppression could take place. As this document focuses on the harmful results of adverse actions not the causes nor motivations of adverse actions, we authors don’t note this case specially you just mentioned.  Anyway, we authors will be considering this comments from you when updating this draft in its next version.
