RAN Security

RAN Security Training by Tonex

The Radio Access Network (RAN) connects mobile devices to network services through radio equipment, base station functions, transport links, and supporting management systems. RAN Security Training by Tonex examines the security responsibilities of these components in Fifth Generation (5G) deployments, including distributed and open-interface architectures. Participants review protected radio signaling, network element authentication, management access, configuration assurance, interface exposure, and supplier coordination. The course emphasizes design and operational decisions that protect the access network without overstating the protection provided by any single security protocol.

Effective radio access safeguards strengthen cybersecurity by reducing exposure at network entry points and operational interfaces. Coordinated oversight also enhances cybersecurity resilience through trusted configurations, continuous monitoring, and controlled maintenance access.

A practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in ran security projects.
