Defensive 5G

Presented at DEF CON 30 (2022), Aug. 13, 2022, noon (115 minutes).

In this work we developed a 4.5G/5G network using only commercial off the shelf (COTS) hardware and open-source software to serve as test-infrastructure for studying vulnerabilities in 5G networks. We are using software defined networking (SDN) tools such as Faucet and Dovesnap and software defined radio(SDR) capabilities such as Open5gs and srsRAN along with Docker Containers to facilitate the rapid and reliable setup and configuration of network topologies that can be used to represent the 5G networks that we intend to test. By having a configurable and repeatable mechanism that could be shared among multiple users with differing hardware setups we were able to test 5G network configurations in a variety of ways and have those results validated by other team members.

Audience: Target Audience: Network Defense and Attack, 5G, Software Defined Radio and Infrastructure-as-Code.
