Airport security refers to the measures and protocols implemented to ensure the safety and protection of passengers, staff, and aircraft at airports. This encompasses a range of activities, including screening passengers and their baggage for prohibited items, monitoring airport facilities, maintaining perimeter security, and deploying security personnel. The primary objective of airport security is to prevent acts of unlawful interference, such as terrorism, hijacking, or smuggling, while facilitating the smooth operation of air travel. Security procedures commonly involve the use of metal detectors, x-ray machines, body scanners, and enhanced surveillance systems. Additionally, airport security includes the vetting of airport employees and the clearance of cargo. Overall, airport security plays a crucial role in safeguarding public safety in air travel.
