In aviation security, "layered security" refers to the implementation of multiple security measures designed to create a comprehensive protective environment against a variety of threats. This approach recognizes that no single security procedure is completely effective on its own. Instead, by combining various strategies—such as screening processes, surveillance systems, physical barriers, and personnel training—aviation security creates several layers of defense that work together to mitigate risks.

This method enhances the overall security framework by addressing potential vulnerabilities at different stages of the travel process, from ticketing and check-in to boarding and in-flight security. It is particularly important in an environment where threats can be diverse and evolving, requiring adaptations and constant vigilance. The strategic layering of security measures improves detection, deterrence, and response capabilities, ultimately fostering a safer aviation environment for passengers and crew.
