In the context of security, what does "access control" mean?

Access control refers to the systems and processes used to regulate who is allowed to enter or exit a facility. This is a fundamental aspect of security management aimed at protecting people, property, and information. By establishing protocols for controlling access, organizations can ensure that only authorized personnel gain entry to specific areas, thereby minimizing the risk of theft, vandalism, or unauthorized activities.

This concept encompasses various methods, such as key cards, biometric scanners, security guards, and visitor logs, which work together to provide a secure environment. It’s crucial because effective access control helps maintain the integrity of sensitive areas, enhancing overall security within a facility. This focus on entry and exit management distinguishes access control from other security measures that might deal with different aspects, such as monitoring attendance or controlling internet usage.
