Roaming Security Assessment

A roaming security assessment is a structured audit of the controls protecting a subscriber's traffic while attached to a visited network. It examines interconnect agreements, SS7/Diameter/N32 firewall policies, encryption of inter-PLMN links, monitoring coverage, and incident response, mapping findings against GSMA FS.07/FS.11/FS.19 and operator-specific risk appetite.

Roaming Security Assessment in context

Signaling protocols carry the control-plane messages that set up calls, register subscribers 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 as top-tier telecom risk.

Roaming and interconnect are where two operators 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 Roaming Security Assessment in the wider telecom-security picture, review Behavioral Signaling Detection, FS.11, GRE, Roaming, Roaming Interconnect Security and Signaling Screening — each entry cross-references back to this page so you can walk the topic in either direction.
