What does "access control" refer to in a security context?

Access control in a security context primarily refers to regulating entrance and exit to a specific area. This involves implementing systems and procedures that dictate who is allowed to enter or exit a space and when they can do so. Effective access control can include various methods, such as identification verification (using ID badges, biometric systems, or access codes) to ensure that only authorized individuals gain entry, thereby enhancing the overall security of an organization or facility.

While monitoring employee performance, providing customer service at entrances, and setting up security barriers are important aspects of security operations, they do not specifically define access control. Instead, these elements can be considered complementary to the main objective of access control, which is to manage and restrict access to secure areas effectively.
