IPv6

The next-generation IP protocol with 128-bit addresses. IPv6 was designed with optional IPsec support, but IPsec is not mandatory in all deployments. IPv6 security depends on implementation policies, not the protocol alone.

IPv6 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 IPv6 in the wider telecom-security picture, review IKEv2, OSPF, TR-069, RPKI-to-Router, A5/1 and SIRT.
