What is the definition of access control?

Access control is defined as the ability to limit entry into controlled spaces based on authorization. This means that access control systems are designed to restrict who can enter a specific area or system to only those individuals who have been granted permission, thereby ensuring security and safety. This is essential in various environments, such as workplaces, secure facilities, and digital systems, where sensitive information or secure locations need protection from unauthorized access.

The concept of access control encompasses various methods, such as physical barriers, identification systems, and digital authentication processes, all aimed at enforcing security protocols. By managing who can enter certain spaces or access specific information, organizations can safeguard against potential threats, breaches, or unauthorized activities.

In contrast, the other options focus on aspects related to security but do not specifically capture the essence of access control. For example, securing sensitive information or managing employee entry may be components of broader security measures, but they do not specifically define access control as the act of limiting entry based on authorization. Similarly, security measures for personal belongings pertain to a different area of security that is not exclusive to access control mechanisms.
