Access control involves the mechanisms and policies put in place to regulate who can enter or exit specific areas within a facility. This concept is crucial for maintaining security in various environments, such as corporate offices, warehouses, or restricted areas, as it helps prevent unauthorized access and protects sensitive information or valuable assets.

By implementing access control measures, such as key cards, biometric scanners, or security personnel, organizations can ensure that only authorized individuals are permitted in certain locations, thereby reducing the risk of theft, vandalism, or other security breaches. This practice not only safeguards physical space but also contributes to the overall safety and compliance of the organization with relevant regulations and standards.

The other options pertain to different operational aspects that do not align with the purpose of access control. Monitoring employee shifts relates more to workforce management, tracking inventory levels concerns stock and supply chain management, and conducting employee interviews focuses on human resources processes. Each of these plays a distinct role in organizational functionality but does not encompass the essence of controlling access to physical spaces.
