Enhancing Physical Perimeter Defense Using Software-Defined Radio

Explore an innovative approach to enhancing physical perimeter defense using Software-Defined Radio (SDR) in this 24-minute conference talk from AppSecUSA 2017. Learn about the limitations of traditional sensor-based perimeter defense systems and discover how SDR technology can be leveraged to simulate cell tower signals within a short range near protected perimeters. Understand the technical implementation details, including SDR configuration, data storage, and analysis techniques for identifying potential threats, conducting post-breach investigations, and aiding in convictions. Examine the solution's capabilities in detecting reconnaissance activities, abnormal devices, and intrusions, as well as its integration potential with existing security systems and drones. Consider the limitations and ethical implications of this approach while gaining insights into advanced features and similar ideas in the field of physical security.
