what is physical security

Physical security refers to the measures taken to protect personnel, equipment, facilities, and resources from unauthorized access, damage, or harm caused by physical actions and events. Physical security involves the use of multiple layers of interdependent systems, including CCTV surveillance, security guards, protective barriers, locks, access control, perimeter intrusion detection, deterrent systems, fire protection, and other systems designed to protect persons and property. The physical security framework is made up of three main components: access control, surveillance, and testing. Access control refers to the methods used to restrict access to a facility or resource, while surveillance involves the use of cameras and other monitoring systems to detect and deter threats. Testing involves regular assessments of the physical security system to identify vulnerabilities and improve its effectiveness. Physical security is a preventative measure and incident response tool, and it is essential for protecting people, property, and assets from physical threats.
