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 draft is ready. All previously identified potential issues (see [1]) seem to have been addressed. For the security ADs, please review the summary I wrote at [1], which is still applicable. For the opsawg folks, if (when?) you get around to describing how software packages might be able to convey their intended use and/or preferred configuration, let me know - I'd like to help.
