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

The term "access control" specifically refers to the methods and systems that regulate who may enter or exit certain areas. This includes a variety of practices and technologies, such as key cards, biometric scanners, and security personnel, that are employed to ensure that only authorized individuals can access restricted locations. By implementing effective access control measures, organizations can minimize the risk of unauthorized entry, thereby enhancing the overall security of their facilities.

Understanding access control is crucial for security officers, as it not only involves physical measures but also encompasses policies and procedures tailored to maintain the integrity and safety of the environment they are tasked with protecting. This approach encompasses not just who can enter an area, but also how they can be monitored and what actions can be taken to enforce the access policies.
