What is a layered security system?

A layered security system refers to an approach that employs a variety of security measures across different layers or aspects of an organization to address potential threats. This strategy is particularly effective in aviation security because it creates redundancies and utilizes multiple methods to provide a comprehensive defense against a range of potential security risks. By integrating diverse measures—such as physical barriers, surveillance technology, personnel training, and procedural protocols—this system enhances the overall security posture.

In aviation, this could involve not just traditional screening processes at checkpoints but also measures like behavioral detection, access control for secure areas, and ongoing threat assessments that dynamically adjust to the security landscape. The goal is to create a robust defense that makes it more difficult for any single threat to exploit vulnerabilities, thereby enhancing the safety of passengers and operations. This multifaceted approach is critical in environments where safety is paramount and where threats can be both complex and evolving.
