"Consistent with the President's National Security Strategy, this new NSAS [National Strategy for Aviation Security] focuses first on protecting the United States and its interests. It broadens the scope of potential threats to, or disruption of, the Aviation Ecosystem beyond the previous more narrow focus on terrorist groups, criminals, and hostile nation states to also include insiders, foreign intelligence activities, and the spread of infectious disease via air travel. The new NSAS directs a holistic and adaptive approach to securing the Aviation Ecosystem that prioritizes enhanced domain awareness, collection of anticipatory information, augmentation and sustainment of layered security measures, improved system resilience, and effective engagement with government and private-sector partners. The NSAS underscores the importance of, and recognizes the interdependent roles of, Federal, State, and local authorities, the private-sector, and international partners to securing the system and facilitating aviation safety and commerce."
