A Layered Approach to Threat Modeling for 5G-Based Systems

The rise of 5G networks promises a wide range cutting-edge services with the aim achieving high performance and reliability. Cutting-edge applications facilitated by architecture make use various enabling technologies, which introduce new emerging security threats attacks. Threat modeling is proactive approach to identify requirements, as well potential vulnerabilities, prioritize remediation methods. In addition, are complex usually divided into separate layers foster understanding management different functionalities. open nature envisages that multiple vendors service providers might be working on network deployment provisioning; it therefore necessary address categorize at each layer distinctly. This paper presents threat model for 5G-based systems. It leverages layered architecture, identifying categories mapping these corresponding layers. also analyzes technologies affected identified along actors, entry points, impact categories. Through development this model, we envisage facilitating further research specific mechanisms protect against them.
