Drone defense: SHIELD fights Cyberattacks

Florida International University (FIU) researchers have unveiled a new cybersecurity framework called SHIELD, designed to defend drones from cyberattacks that could hijack their systems mid-flight. The innovation aims to help unmanned aerial vehicles (UAV) detect and recover from digital intrusions, ensuring they can safely complete their missions.

Developed by a team led by Mohammad Ashiqur Rahman, an associate professor in FIU’s Knight Foundation School of Computing and Information Sciences, SHIELD was presented at the IEEE/IFIP International Conference on Dependable Systems and Networks. The system continuously monitors a drone’s entire control network, its sensors, hardware, and actuation systems to detect irregularities that signal an attack. Using artificial intelligence and machine learning, SHIELD identifies the type of cyber intrusion and activates a tailored recovery protocol within fractions of a second. The technology was developed in response to limitations in current drone-defense methods, which often focus only on sensor data and fail to detect deeper, system-level threats.

Experts say the timing of SHIELD’s introduction is significant. With the Federal Aviation Administration proposing to expand commercial drone operations across industries from delivery services to agriculture the need for robust security mechanisms is becoming critical. Rahman emphasized that SHIELD not only detects attacks but also allows drones to recover and continue their missions, potentially reducing downtime and financial losses. As FIU’s research group moves toward real-world testing, they hope the system will play a key role in building safer, more resilient drone technologies for the growing autonomous aviation industry.
