Quick Summary

Physical security refers to the protection of people and property from various hazards, including crime, fire, and accidents. It encompasses both tangible means, like building design and security equipment, and intangible measures, such as personnel screening and management controls.1

Key aspects of physical security include:
* Building Architecture: Designing structures with controlled entrances, exits, and traffic patterns.1
* Equipment and Devices: Utilizing safes, communication systems, identification tools (like badges and access control systems), intrusion detectors, and surveillance equipment.1
* Personnel Security: Implementing measures to recruit trustworthy individuals through background investigations and other screening methods.1
* Biometrics: Employing unique physical characteristics (fingerprints, faces) or behavioral traits (voice patterns) for identity verification and access control.2

The goal is to prevent unauthorized access, theft, and other threats through a combination of physical barriers, technological solutions, and human oversight.12
