How is "access control" defined in a physical security context?

In a physical security context, "access control" is defined as the process of regulating who can enter or use resources in a facility. This involves implementing policies, procedures, and physical measures to restrict access to only authorized individuals. Access control mechanisms can include key card systems, biometric scanners, security badges, and visitor management systems, all designed to ensure that only those with proper authorization can gain entry to sensitive areas or utilize particular resources, such as equipment or information.

This definition underscores the importance of safeguarding a facility's physical and informational assets by ensuring that access is granted based on verified identity and compliance with security protocols, ultimately bolstering the overall security posture of the organization. By controlling access, organizations can prevent unauthorized entry and potential security incidents, thereby protecting personnel, assets, and information.
