RAN Attack Detection

RAN Attack Detection Training by Tonex

Modern fifth-generation (5G) radio access networks (RANs) expose security teams to diverse signals from base stations, radio interfaces, transport connections, and management platforms. RAN Attack Detection Training by Tonex develops a systematic approach to identifying suspicious activity without mistaking ordinary interference or equipment faults for confirmed attacks. Participants assess changes to base station identities, configuration integrity, administrative behavior, availability indicators, and network telemetry. Particular attention is given to the evidence needed for defensible triage, correlation across domains, and coordinated investigations with engineering teams.

Timely detection strengthens cybersecurity by revealing unauthorized access and network manipulation. Evidence-based escalation also improves cybersecurity resilience while protecting subscriber connectivity and essential services.

The practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in RAN attack detection projects, including event correlation worksheets, evidence registers, and coordinated escalation procedures.
