Abstract
Electromagnetic spectrum (EMS) attacks seek to take advantage of vulnerabilities at electromagnetic radiation frequencies in order to disrupt, control, or eavesdrop on communications and operations in cyber-physical systems. In this paper, we introduce an inexpensive and modular EMS threat monitoring system that provides real-time detection and visualization of cyber electromagnetic threats. At the hardware level, the system is realized with low-cost hardware modules like Software Defined Radio (SDN), Raspberry Pi, and GPS modules. At the software level, bespoke Pyhton-based scripts have been created, with the ability to both simulate and detect electromagnetic threats like GPS spoofing, wireless network impersonation, and signal jamming. For each attack studied, practical mitigation controls for operational deployment are outlined. The efficacy and agility of the proposed platform have been validated by carrying out controlled experiments in a cyber range setup. Finally, future directions are discussed, that can further enhance the EMS threat detection capabilities of the proposed platform.
