Last Call Review of draft-ietf-ace-usecases-09
review-ietf-ace-usecases-09-secdir-lc-montville-2015-10-15-00

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.

Draft is Ready with nits and one possible issue.

This draft seems to provide a good set of use cases collectively representing
the lifecycle of constrained devices up to and including decommissioning.

While the draft does mention “configuration”, the context is more about
ensuring flexibility of expressing access permissions.  I’m not sure if this
draft requires something like the following, but it would be beneficial for
downstream operational processes to explicitly support endpoint posture
assessment.  This could be done by providing an explicit posture-related
interface.  Such a requirement could be alluded to in the Security
Considerations section.  On the other hand, this may be something addressed by
CoAP and other drafts.

Nits (against -09):

Second paragraph of 3.1: You might consider adding a sentence indicating
whether developers are expected to do anything after becoming familiar with
RFC7258.

Third paragraph of 3.1: Formatting issue after first sentence - second sentence
is on a new line, or the second sentence was intended to start a new paragraph.

Third paragraph of 3.1: s/attacks/attack/

Fifth paragraph of 3.1: Formatting issue after second sentence - third sentence
is on a new line, or the third sentence was intended to start a new paragraph.

Kind regards,

Adam
