What does the term "access control" refer to in security?

The correct answer is that "access control" refers to measures taken to restrict access to a facility or area. This concept is essential in security management, as it ensures that only authorized individuals can enter specific locations, thereby protecting sensitive information, assets, and the overall safety of the premises. Access control can be implemented through various methods, including physical barriers like locks and security guards, as well as technological solutions such as electronic access cards and biometric systems.

By controlling who can enter a site and under what circumstances, organizations can minimize the risk of theft, vandalism, or other security breaches. It establishes a systematic way to manage entry points and maintain a secure environment, which is critical for the effectiveness of security protocols within any organization.
