Access control is a crucial component of security operations that focuses on the protocols and measures taken to limit entry to a facility or specific areas within a facility. It is designed to prevent unauthorized individuals from gaining access to sensitive locations, thereby protecting assets, personnel, and information. This can include physical barriers such as locked doors, security badges, and biometric systems, as well as procedural measures that require identification or authorization for entry.

Restricting entry to unauthorized individuals is fundamental in maintaining a secure environment. It involves assessing who is allowed access based on predetermined criteria, ensuring that only those with legitimate reasons can enter certain areas. This function is proactive in preventing security breaches, potential theft, or harm.

In contrast, the other options—monitoring employee activities, implementing emergency response plans, and screening visitors—are relevant to security but do not specifically define access control. Monitoring employees pertains more to surveillance and behavior tracking, emergency response plans deal with actions taken during a crisis, and screening visitors relates to processes that may occur at the point of entry but do not encompass the broader scope of access control, which primarily focuses on authorization and entry restrictions.
