Vulnerability Management

In telecom networks, Vulnerability Management is the continuous process of discovering, prioritizing, remediating, and verifying vulnerabilities across radio, core, signaling, OAM, and IT estates. It accounts for telecom-specific constraints such as long vendor patch cycles, change windows tied to roaming partners, and the need to coordinate fixes across 3GPP-defined network functions and interconnect peers.

Vulnerability Management in context

The radio access network is where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations and downgrade attacks; defenses rest on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.

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.

To place Vulnerability Management in the wider telecom-security picture, review 5G SA, AMF, Base Station (BS), Capacity Planning, CAPEX and CSCF — each entry cross-references back to this page so you can walk the topic in either direction.
