3G (Third Generation Mobile Network)

Mobile network technology emerging in the early 2000s offering significantly faster data speeds (up to 2 Mbps) than 2G. Standards like UMTS (Universal Mobile Telecommunications System) and CDMA2000 enabled mobile internet browsing, video calling, and multimedia services. 3G introduced stronger authentication (AKA) and improved encryption compared to 2G.

3G 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 3G in the wider telecom-security picture, review 3GPP, 6G, AES, DOCSIS, GSMA Permanent Reference Documents (IR Series) and LEO.
