Ballot Text

Technical Summary

   Transport Layer Security (TLS) and Datagram Transport Layer Security
   (DTLS) are widely used to protect data exchanged over application
   protocols such as HTTP, SMTP, IMAP, POP, SIP, and XMPP.  Over the
   years, the industry has witnessed several serious attacks on TLS and
   DTLS, including attacks on the most commonly used cipher suites and
   their modes of operation.  This document provides recommendations for
   improving the security of deployed services that use TLS and DTLS.
   The recommendations are applicable to the majority of use cases.

   This document was published as RFC 7525 when the
   industry was in the midst of its transition to TLS 1.2.  Years later this
   transition is largely complete and TLS 1.3 is widely available.  Given the
   new environment, updated guidance is needed.

Working Group Summary

   The only significant challenge has been that the TLS working group keeps getting proposed
work that should really have been sent to UTA and the RFC7525 bis work much more quickly. This has led to a number of "resets" and two separate WGLCs.

Document Quality

   The document is clear and has been widely cited and used in the industry.

Personnel

   Leif Johansson is the Document Shepherd, Francesca Palombini is the Responsible Area Director.
