Monitoring
Categories: SignalingRoaming and InterconnectSecurity Controls
Monitoring in context
Signaling protocols carry the control-plane instructions that set up calls, register subscribers, hand over sessions and route SMS. SS7, Diameter, GTP-C and SIP are the four dominant families, and interconnect exposure of any of them is treated by GSMA FS.11 / FS.19 / FS.20 as a top-tier telecom risk.
Roaming and interconnect are where two operators, often with an IPX or GRX carrier in between, exchange signaling and user-plane traffic. Trust boundaries here are the primary attack surface for location tracking, SMS interception and fraud, which is why GSMA now mandates SEPP with PRINS on 5G interconnect.
To place Monitoring in the wider telecom-security picture, review Signaling Firewall, Integrity, Detection Engineering, Mitigation, MSSP and Session Border Controller (SBC).
