3GPP (Third Generation Partnership Project)

3GPP in context

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.

OSS/BSS platforms hold the highest-value subscriber and revenue data on the operator side, are heavily targeted for fraud and insider abuse, and are in scope for NIS2 and the UK Telecoms Security Act.

To place 3GPP in the wider telecom-security picture, review 3G, IP, Zeroconf, ZSM, GSMA Permanent Reference Documents (IR Series) and LEO: each entry cross-references back to this page so you can walk the topic in either direction.
