Defensive 5G: Studying Vulnerabilities in 5G Networks

Explore the security implications of 5G technology in this 22-minute conference talk from GNU Radio Conference 2021. Delve into the promises and potential vulnerabilities of 5G networks as presenter Eric Mair discusses the shift to internet protocol (IP) for traffic transport and the increased reliance on cloud computing, SDN, and SDR capabilities. Learn about the development of a 4.5G/5G network using commercial off-the-shelf (COTS) hardware and open-source software as a test infrastructure for studying vulnerabilities. Discover how tools like Faucet, Dovesnap, Open5gs, and srsRAN are utilized to rapidly set up and configure network topologies for testing various 5G use-cases. Gain insights into the red-team/blue-team approach employed to validate potential vulnerabilities in 5G networks.
