Second Draft of Trustworthy Email Specification, SP 800-177 Revision 1
December 15, 2017

Draft NIST Special Publication 800-177 Revision 1, Trustworthy Email, covers and gives recommendations for state of the art email security technologies to detect and prevent phishing and other malicious email messages. The guide was written for email administrators and for those developing security policies for an enterprise email infrastructure.

This second comment period for Revision 1 is to allow for comments on a newly included security recommendation dealing with mail confidentiality. This revision also includes more text on new email security protocols currently undergoing specification and finalization as IETF Draft Standards. Reviewers should pay particular attention to Sections 5.2 and 7.3, which has newly-added material.

Comments are due by January 31, 2018. See the publication record for additional details and a copy of the draft.
