RAN Incident Investigation Training by Tonex
Radio Access Network (RAN) incident investigation involves reconstructing faults and suspected intrusions from distributed access-node records, signaling observations, management changes, and mobility events. RAN Incident Investigation Training by Tonex examines fifth-generation (5G) access evidence across centralized and distributed deployments. Participants learn to distinguish expected handovers, coverage degradation, and software changes from activity that warrants a cybersecurity investigation. Cybersecurity analysis requires care with radio identifiers, incomplete captures, and core correlation. The course emphasizes lawful acquisition, accurate timelines, impact assessment, and bounded conclusions. Its practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in radio access incident investigation projects.
