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. This draft describes usage for managing mixers used in media conferences and connections. The security considerations section does exist and references the XML media RFC, 3023, with the possible implications of using XML for command and display purposes. In regards to media mixer usage this draft references the control framework draft, draft-ietf-mediactrl-sip-control-framework, for security issues regarding session establishment, transport protection, and control channel policy management. After reading the referenced drafts I believe that there are no additional threats that the draft-ietf-mediactrl-mixer-control-package draft does not already account for. General comment(s): None. Editorial comment(s): Security considerations: Section 11 of [I-D.ietf-mediactrl-sip-control-framework] is incorrectly referenced, should reference 12. This occurs 3 times. -- Shawn.
