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:

The U.S. National Airspace System (NAS) maintains a comprehensive, multi-layered security framework, led by the Air Traffic Organization's System Operations Security, which has significantly reduced aviation threats since 9/11.
Security operations are structured into Tactical (real-time response), Special (planning and coordination), and Strategic (large-scale threat assessment and policy) groups, all engaged in extensive collaboration with numerous interagency partners.
The Domestic Events Network (DEN) is a critical 24/7 communication platform connecting over 100 agencies to identify and coordinate responses to real-time anomalies and suspicious activities in the NAS, such as extended loss of communication or unusual flight plan changes.
Beyond physical threats, the aviation system faces growing cybersecurity risks, including unauthorized access, denial-of-service attacks, and ransomware, due to the increasing integration of information and communication technology.

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.
