Vulnerability Assessment

In telecommunications, a Vulnerability Assessment is a structured review of network functions, signaling perimeters, and supporting systems to identify known weaknesses (CVEs, misconfigurations, exposed interfaces) without necessarily exploiting them. It typically combines automated scanning of telecom-specific protocols (SS7, Diameter, GTP, HTTP/2 SBA) with manual review of vendor advisories, 3GPP specifications, and operator configuration baselines.

Vulnerability Assessment in context

The mobile core carries subscriber sessions, mobility and policy. In 4G it is the EPC (MME, HSS, S/PGW); in 5G it is the Service-Based Architecture with AMF, SMF, UPF, AUSF, UDM and the NRF.

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.

To place Vulnerability Assessment in the wider telecom-security picture, review Threat Hunting (Telecom), Telecom Forensics, NTA, 5G SA, 5G SBA and ACL — each entry cross-references back to this page so you can walk the topic in either direction.
