I have reviewed draft-ietf-syslog-sign-27 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 document describes a mechanism, called syslog-sign in this document, which adds origin authentication, message integrity, replay resistance, message sequencing, and detection of missing messages to syslog.   I sent the review of draft-ietf-syslog-sign-27 some time ago. I re-checked the draft-ietf-syslog-sign-28. I have no more further comments.     B. R. Tina http://tinatsou.weebly.com/contact.html
