XMPP (Extensible Messaging and Presence Protocol)

Extensible Messaging and Presence Protocol is the IETF XML-based standard (RFC 6120) for near-real-time messaging, presence, and request-response services. It powers federated chat networks, parts of messaging clients (including major consumer chat platforms), gaming and IoT messaging. XMPP supports TLS, SASL authentication, and end-to-end extensions such as OMEMO.

XMPP in context

Security controls span signaling firewalls (SS7/Diameter/GTP screening), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36.

Telecom security is written into standards from 3GPP, GSMA, ETSI, IETF and ITU-T. Understanding which body owns which specification, and how they interlock, is essential for both design and audit work.

To place XMPP in the wider telecom-security picture, review SRTP, DTLS-SRTP, NAF, HKDF, 3G and 6G — each entry cross-references back to this page so you can walk the topic in either direction.
