AetherGuard: Protecting the Mobile Core Network Elements via Air-Gapped Hardware Verification and Code Execution Tracking
Abstract
The goal of the project is to develop, refine, and characterize novel non-intrusive technologies for identifying firmware-level and runtime exploitation of critical devices. AetherGuard allows DHS and other customers to confirm the integrity of critical embedded/closed devices with no manufacturer assistance. In that respect, we developed prototypes to verify the firmware/software of a variety of devices. These devices include SEL351S devices [1], which are commonly used in data centers and other high-power environments, Raspberry PIs [2] (as proxies for 5G hotspots and pico cells), T-Mobile CellSpots [3], and Nokia AirScale system modules [4]. In the beginning of the effort, we also obtained some prior results on an SEL-2740S Software-Defined Network Switch (SDN) [5] and Allen-Bradley PLCs [6] (which are extensively used in data centers and cell towers/installations).
