Aviation Cybersecurity: Enhanced Air Safety Requires FAA to Better Mitigate Threats to Aircraft Communications

What GAO Found The Federal Aviation Administration (FAA) has identified electromagnetic spectrum-related threats, including spoofing and jamming, to the National Airspace System (NAS) and international flight routes. However, FAA has not completed risk and mitigation assessments, and updated security documentation needed to address these threats. Additionally, FAA did not have a defined, real-time monitoring and detection capability for all spectrum-related threats.
