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 I-D documents requirements for extensions of the data tracker and as such has no impact on the security of the Internet at large. The Security Considerations section spells out privacy concerns for users of the data tracker although it does not require that security protocols are mandatory to implement for the data tracker, which is kind of what I expected this document would say. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1, 28759 Bremen, Germany Fax: +49 421 200 3103 < http://www.jacobs-university.de/ >
