5G Threat Modeling

5G Threat Modeling Training by Tonex

Security threats in Fifth Generation (5G) systems often cross organizational and technical boundaries, from radio access to service-based core interfaces and cloud-hosted infrastructure. 5G Threat Modeling Training by Tonex provides a structured method for identifying protected assets, trusted interactions, potential adversary actions, and plausible failure conditions. Participants construct architecture-based threat scenarios, examine attack paths, compare mitigating controls, and document uncertainty. Special attention is given to network slice boundaries, privileged management access, service discovery, and supplier dependencies without assuming every theoretical threat is equally likely.

Systematic threat modeling improves cybersecurity by revealing design weaknesses before deployment. Documented scenarios strengthen cybersecurity decisions by connecting preventive controls, detection needs, and residual risk ownership.

A practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in 5g threat modeling projects.

• Assess service interface authentication and authorization failure paths
• Evaluate interconnection and roaming trust boundary exposure scenarios
• Identify risks from insecure network function configuration changes
• Connect each threat to the relevant network architecture elements

Module 5: Mitigation Prioritization and Ownership

• Map each material threat to existing and proposed security safeguards
• Consider traffic separation, access controls, and protected communications
• Identify monitoring and response gaps for credible abuse cases
