In a security context, what does the term 'access control' refer to?

The term 'access control' specifically refers to the practices and technologies used to regulate who can enter or exit a designated area. This involves establishing permissions for individuals based on their roles, responsibilities, or security clearance levels. Access control is essential in maintaining security as it helps prevent unauthorized access to sensitive or restricted areas, thereby protecting property, personnel, and information.

In a security framework, access control can involve physical barriers, such as locked doors, security guards, or turnstiles, as well as electronic systems like keycards, biometric scanners, and coded entry systems. The underlying principle is to ensure that only those who have the appropriate authorization are permitted entry, and that individuals who are not authorized are effectively denied access.

The other choices do not align with the primary concept of access control. Monitoring employee performance concerns personnel evaluations and productivity, managing lost and found items pertains to the handling of misplaced belongings, and setting up surveillance cameras is related to surveillance practices rather than directly regulating access to specific areas. Each of these activities may be part of a broader security strategy but does not specifically define access control.
