DRP (Disaster Recovery Plan)

A Disaster Recovery Plan documents the technical and organisational procedures for restoring services after major disruption, natural disaster, large-scale outage, ransomware. For a telecom operator, the DRP covers core network elements, OSS/BSS, customer-facing services, and the dependencies between them, and is exercised regularly through tabletop and live drills.

DRP in context

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

The mobile core is where subscriber sessions, mobility and policy live. 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. Core exposure is the difference between a single-subscriber leak and a fleet-wide breach.

To place DRP in the wider telecom-security picture, review Operating System (OS), QoS, Fuzzing, Interconnection, MNO and Red Team.
