Dear all,

In the latest version of the draft (which we just posted, see below) we have addressed many of the DICUSSES we had received from the IESG (we believe we have addressed the ones from Sean Turner, Tim Polk, and Alexey Melnikov). However, we did not yet address all the DISCUSSES and COMMENTS (the ones from Peter Saint-Andre and Robert Sparks we did not yet get to).

 - Jan

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Session PEERing for Multimedia INTerconnect Working Group of the IETF.

	Title           : Session Peering for Multimedia Interconnect (SPEERMINT) Security Threats and Suggested Countermeasures
	Author(s)       : J. Seedorf, et al.
	Filename        : draft-ietf-speermint-voipthreats-08.txt
	Pages           : 27

The Session PEERing for Multimedia INTerconnect working group
(SPEERMINT) provides a peering framework that leverages the building blocks of existing IETF-defined protocols such as SIP and ENUM for the interconnection between SIP service providers.  The objective of this document is to identify and enumerate SPEERMINT-specific threat vectors and to give guidance for implementers on selecting appropriate countermeasures.  Security requirements for SPEERMINT which have been derived from the threats detailed in this document can be found in draft-ietf-speermint-requirements; this document provides concrete countermeasures to meet those SPEERMINT security requirements.  In this document, the different security threats related to SPEERMINT are classified into threats to the Lookup Function (LUF), to the Location Routing Function (LRF), to the Signaling Function (SF), and to the Media Function (MF) of a specific SIP Service Provider (SSP).  Various instances of the threats are briefly introduced inside the classification.  Finally, existing security solutions for SIP and RTP/RTCP are presented to describe countermeasures currently available for such threats.  Each SSP may have connections to one or more remote SSPs through peering or transit contracts.  A potentially compromised remote SSP which attacks other SSPs is out of the scope of this document; this document focuses on attacks on an SSP from outside the trust domain such an SSP may have with other SSPs.
