Incident Response

Incident response is the structured process of preparing for, detecting, containing, eradicating, recovering from, and learning from security incidents, formalised in standards such as NIST SP 800-61 and ISO/IEC 27035. Telecom incident response extends classic IT scope to signalling, RAN, and lawful-interception assets and demands tight coordination with regulators.

Incident Response 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.

Telecom threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking. The common thread is that most attacks exploit the inherited trust model of legacy signaling protocols.

To place Incident Response in the wider telecom-security picture, review ETSI, Modulation, OT, RTSP, Telnet and X1 — each entry cross-references back to this page so you can walk the topic in either direction.
