ETSI (European Telecommunications Standards Institute)

The European Telecommunications Standards Institute is a non-profit standards organisation based in Sophia Antipolis, France, that produces telecom and ICT standards used globally. ETSI is one of the seven Organisational Partners of 3GPP, and authors security-critical specifications including the Lawful Interception series (TS 102 232/103 221), the EN 303 645 IoT security baseline, and many MEC and NFV standards.

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