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.


Over the last few years there have been several serious attacks on
   Transport Layer Security (TLS), including attacks on its most
   commonly used ciphers and modes of operation.  This document
   summarizes these attacks, with the goal of motivating generic and
   protocol-specific recommendations on the usage of TLS and Datagram
   TLS (DTLS).

I consider this document ready for publication.

This document is an Information draft, summarizing somer of the known attacks on TLS and DTLS.

I agree with the security considerations section statement that this document has no security implications.

A few editorial nits:
