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.

These document updates RFC6045 - Real-time Inter-network Defence (RID)

The document defines a way to communicate IODEF objects between Service
Providers. In general I find the document well written and I especially
like the way the XML schema is described in ASCII graphics.

A few comments:

- - The term "Network Provider" is still used in parts of the document
where it might be better to be consistent with the new term "Service
Provider" (the name-change is announced in the introduction).

- - The introduction states that the document moves RFC6505 to Historic
status and also that it updates RFC6505. This is confusing to me. It
seems like this is a simple case of an update that changes the document
status (Informational -> Standards Track) and I'm not sure Historic
needs to enter into it.

- - The discussions on PKI issues and trust is quite good but I would
have liked to see an explicit mention of the fact that strong name-
key binding is the key to establishing a good trust infrastructure. The
use of PKI is strongly encouraged but for smaller consortia it would
be entirely feasible to establish the required level of trust by
manually sharing keys instead of running a PKI.

- - The security considerations section re-iterates a dependency on PKI
and PKI federations to fulfill the trust requirements of RID consortia.
However it is worth noting that very few examples of the type of PKI
federations that RID depend on, exist in the wild.

	Cheers Leif
