physical accessnounMWEThe ability of people to physically gain access to a computer system or facility.verified
physical access controlnounMWEA mechanism, system, or barrier that prevents unauthorized physical access to an area or a facility.verified
physical access control systemnounMWEPhysical access control enables an authority to control admission to areas and resources in a physical facility. A physical access control system may restrict access via swipe cards, Personal Identity Verification (PIV) 'Smart' cards, and biometric (i.e. fingerprint) readers. Physical access control systems are generally seen as the second layer in the security of a physical facility after fences, doors and barriers.verified
Physical Access Control system maintenance and testing programnounMWEA documented listing of procedures, schedules, roles and responsibilities, and plans to be performed to ensure continued maintenance and testing of the Physical Access Control System.verified
physical actionnounMWEA category of security control behavior in which compliance depends on deliberate, in-the-world conduct by a user — handling, carrying, locking away, or otherwise manipulating a tangible object or device — rather than on an automated or purely logical mechanism. NIST SP 800-171r3 uses the phrase in the context that "protection and control of mobile devices are behavior- or policy-based and require users to take physical action to protect and control such devices when outside of controlled areas." This distinguishes it from technical or administrative controls that operate without user involvement: the safeguard only fires if a person acts in the physical world (e.g., securing a device, locking a case, removing media). It is used in standards and compliance frameworks to flag control requirements that cannot be automated and therefore depend on training, policy, and human follow-through for their effectiveness.verified
