Demystifying 5G Security through Threat Modeling

Explore a comprehensive analysis of 5G security risks and mitigating controls in this 46-minute RSA Conference talk by Zhijun Zhang, Lead Security Architect at The World Bank Group. Delve into the new technology components and services of 5G networks, examining potential threats through a custom-developed threat model. Gain insights into the 5G ecosystem's security challenges, including radio access network, core network architecture, trust model, and multi-access edge computing. Learn about the threat modeling process, actors, and actions using the STRIDE+LM framework. Discover how to apply this knowledge to assess risks and implement effective security measures in 5G environments. Prerequisite understanding of threat models such as STRIDE is recommended for maximum benefit from this informative presentation.
