About Airport Security

Airport security refers to the measures and procedures that are put in place to protect passengers, employees, and aircraft at airports. Airport security typically involves a combination of physical security measures, such as gates, fences, and security personnel, as well as technology-based security measures, such as x-ray machines and metal detectors. The goal of airport security is to prevent unauthorized access to aircraft and other sensitive areas of the airport, and to detect and prevent the transport of prohibited or dangerous items. Airport security is typically the responsibility of the airport operator, with oversight from national and international aviation authorities.
