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 in telecom span signaling firewalls (SS7/Diameter/GTP screening at the network edge), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both the packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36 and, in Europe, NIS2 sectoral rules.

Telecom security is written into standards from 3GPP, GSMA, ETSI, IETF and ITU-T. Understanding which body owns which specification, and how the specs interlock (for example 3GPP TS 33.501 with GSMA FS.34 for 5G SBA security), is essential for both design and audit work.

To place XMPP in the wider telecom-security picture, review HKDF, DTLS-SRTP, OASIS, SSH, TR-069 and Zigbee.
