Security in the NAS

In 32 of the last 35 years we have seen aircraft hijackings. How does our Air Traffic Control System combat these and other security threats?

Key Takeaways:

Air traffic control ensures aviation security through the Air Traffic Organization's (ATO) System Operations Security, which comprises Tactical, Special, and Strategic groups that manage real-time threats, develop procedures, and address large-scale security risks.
Post-9/11 enhancements include the 24/7 Domestic Events Network (DEN), a critical communication hub for over 100 agencies to monitor anomalies and coordinate responses to suspicious activities like extended loss of communication or unusual flight diversions.
Controllers are mandated to report various suspicious activities, including prolonged loss of radio contact, unexplained changes in flight destination, and any signs indicating a potential hijacking.
Modern aviation security also faces significant cyber threats, with attacks targeting IT infrastructure through ransomware, denial-of-service, and data corruption, highlighting the need for vigilance beyond physical security measures.

Maintaining safe, secure skies is the name of the game for air traffic control. We have a responsibility to protect not only the people in the air, but the people below. We are proud to accept this responsibility and deliver the safest airspace system in the world. Security in the US National Airspace System (NAS) has seen massive transformation over the last 20-plus years. From that tragic day on September 11, 2001, the world of aviation security has changed and grown into a system that has decreased the average number of yearly hijackings by almost 90 percent.

Airport security plays a large part in this, but air-traffic security procedures add a critical component to aviation security. The ATO (Air Traffic Organization), in partnership with other security groups, works around the clock and year around to monitor and protect the NAS. The many programs and procedures in place are a direct result of a constant effort to improve security in our skies. Understanding the nature of security in the world of aviation, particularly in air traffic control, is a great way to improve the overall safety of the NAS. After all, knowledge is power, and the strength of security in our aviation system protects us all.
