Best Practices for Securing RTP Media Signaled with SIP
RFC 8862, “Best Practices for Securing RTP Media Signaled with SIP”, is a Best Current Practice document published in January 2021 by J. Peterson, R. Barnes, R. Housley. The canonical text is published by the RFC Editor.
Abstract
Although the Session Initiation Protocol (SIP) includes a suite of security services that has been expanded by numerous specifications over the years, there is no single place that explains how to use SIP to establish confidential media sessions. Additionally, existing mechanisms have some feature gaps that need to be identified and resolved in order for them to address the pervasive monitoring threat model. This specification describes best practices for negotiating confidential media with SIP, including a comprehensive protection solution that binds the media layer to SIP layer identities.
What “Best Current Practice” means
Documents the IETF community's recommended operational or procedural practice rather than a protocol specification.
