Developing "Capture the Flag" Challenges for 5G Cyber Security Training

Fifth Generation cellular data systems (5G) are critical infrastructure that deliver IoT, mobile, and broadband services. They have high security demands and complex architectures. Despite the importance of these systems, there is relatively little hands-on training available for 5G engineers and security practitioners. To address this gap, the C5G project is developing a 5G "Capture the Flag" hands-on security training game using an open source Capture the Flag game engine, open source 5G and networking components and tools, and challenges drawn from MITRE Common Vulnerabilities and Exposures (CVEs). This paper explores an example 5G security challenge in depth to illustrate the system design and potential benefits.
