SOAR (Security Orchestration, Automation and Response)

In telecom networks, SOAR platforms automate repetitive incident response actions such as enriching a suspicious global title with reputation data, pushing a temporary block to the SS7 or Diameter signaling firewall, opening a ticket with the roaming team, and notifying the SOC. SOAR playbooks help operators respond to high-volume signaling abuse at machine speed.

SOAR 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.

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 SOAR in the wider telecom-security picture, review Certification Authority (CA), Firewall, IBCF, Interconnect Security Model, Inter-PLMN Security and mTLS — each entry cross-references back to this page so you can walk the topic in either direction.
