What does "access control" mean in security?

Access control in security refers to the systematic regulation of who is allowed to enter or exit a specific facility or area. It encompasses the policies, procedures, and technology designed to ensure that only authorized individuals gain access to sensitive areas, thereby safeguarding both people and property.

This aspect of security is crucial as it helps to prevent unauthorized access, which can lead to theft, vandalism, or other criminal activities. By clearly defining and managing who can enter certain spaces and under what conditions, organizations can maintain a secure environment.

The other options do not accurately define access control. For instance, the first choice implies a complete prohibition of entry, which is not the objective of access control but rather a part of lockdown procedures in specific scenarios. Monitoring employee productivity and controlling the distribution of security uniforms relate to operational management rather than the principles of access control within security frameworks. Hence, focusing on who is permitted to access various areas is the essence of effective access control.
