1.  Introduction

   The Extensible Messaging and Presence Protocol (XMPP) [RFC6120]
   (along with its precursor, the so-called "Jabber protocol") has used
   Transport Layer Security (TLS) [RFC5246] (along with its precursor,
   Secure Sockets Layer or SSL) since 1999.  Both [RFC6120] and its
   predecessor [RFC3920] provided recommendations regarding the use of
   TLS in XMPP.  In order to address the evolving threat model on the
   Internet today, this document provides stronger recommendations.

   In particular, this document updates [RFC6120] by specifying that
   XMPP implementations and deployments MUST follow the best current
   practices documented in the "Recommendations for Secure Use of TLS
   and DTLS" [I-D.ietf-uta-tls-bcp].  This includes stronger
   recommendations regarding SSL/TLS protocol versions, fallback to
   lower versions, TLS-layer compression, TLS session resumption, cipher
   suites, public key lengths, forward secrecy, and other aspects of
   using TLS with XMPP.

2.  Terminology

   Various security-related terms are to be understood in the sense
   defined in [RFC4949].

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in
   [RFC2119].
