The IESG has approved the following document: - 'Recommendations for Secure Use of Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS)' (draft-ietf-uta-rfc7525bis-11.txt) as Best Current Practice This document is the product of the Using TLS in Applications Working Group. The IESG contact persons are Murray Kucherawy and Francesca Palombini. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-uta-rfc7525bis/ 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.
