Zero Configuration Networking

Zero Configuration Networking is the IETF set of techniques (RFC 3927, mDNS, DNS-SD) that let devices discover each other and obtain network configuration without manual setup or central servers. mDNS broadcasts can leak device names and services across networks, so Zeroconf should be confined to trusted segments.

Zeroconf in context

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.

OSS/BSS platforms (provisioning, charging, mediation, order management) hold the highest-value subscriber and revenue data on the operator side. They are heavily targeted for fraud and insider abuse and are increasingly in scope for regulatory obligations like NIS2 and the UK Telecoms Security Act.

To place Zeroconf in the wider telecom-security picture, review 3GPP, ZSM, IP, IP Address, LEO and VPN.
