Hello, 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. Summary: Ready Since my previous secdir review of the -12 version, the comments have all been addressed in a satisfying manner. Typo: ** Remove one « against » in sentence: "In order to protect against against…" Regards, Vincent
