Request Last Call review on draft-ietf-behave-turn-uri by Security Area Directorate Assigned
Completed 2009-10-22
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 document introduces the turn: and turns: URI schemes. The security
considerations point to the relevant documents, one of them being RFC
3958. Section 8 of RFC 3958 states that S-NAPTR application protocols
"should define some form of end-to-end authentication to ensure that
the correct destination has been reached." I think it would be useful
to spell how TURN meets this or whether there are reasons why TURN
does not need such a sanity check. (1-2 sentences should be enough.)
