Security screening is a critical process used to identify and mitigate potential risks in various settings, such as airports, public events, government buildings, and private establishments. It involves the use of technology, such as metal detectors, x-ray machines, and body scanners, along with manual searches and pat-downs, to detect prohibited items, weapons, or dangerous substances. Security screening aims to prevent threats to public safety and security by ensuring that individuals and their belongings are thoroughly inspected before entering a secure area. Additionally, security screening may involve background checks, identification verifications, and profiling techniques to screen individuals for potential risks or threats.
