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 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.

Signaling protocols carry the control-plane instructions that set up calls, register subscribers, hand over sessions 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 FS.11 / FS.19 / FS.20 as a top-tier telecom risk.

To place SOAR in the wider telecom-security picture, review Threat Modeling, IBCF, GRX, SS7 Message Categories, Firewall and Risk Assessment.
