SM-SR (Subscription Manager Secure Routing)

SM-SR 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.

Telecom networks depend on Internet-style routing (BGP, DNS, MPLS) for interconnect. Route hijacks and DNS abuse can degrade or intercept signaling, which is why RPKI and DNSSEC are now standard hardening for carrier networks.

To place SM-SR in the wider telecom-security picture, review SM-DP+, TR-069, RSP, LEO, Network Slicing and PoE: each entry cross-references back to this page so you can walk the topic in either direction.
