What is the function of access control in security?

The function of access control in security is fundamentally about regulating who can enter specific areas. This system is crucial for protecting sensitive information, assets, and ensuring the safety of individuals within a facility. Access control can involve various methods, such as key cards, biometric scanners, or physical guards, to ensure that only authorized personnel are permitted entry into designated areas. This helps to mitigate risks associated with unauthorized access, theft, vandalism, or other security breaches.

In contrast, monitoring employee performance, maintaining inventory of security equipment, and evaluating employee training needs are essential functions of an organization but do not pertain directly to the protective measures associated with access control systems. These activities may support the overall security framework, yet they do not define the core objective of access control, which is fundamentally about controlling entry and securing specific locations.
