What role do access control systems play in physical security?

Access control systems are crucial for establishing and maintaining physical security in various environments, such as buildings and sensitive areas. Their primary function is to define and control entrances and exits, ensuring that only authorized individuals can enter specific areas. This helps to prevent unauthorized access and potential security breaches, protecting both personnel and assets.

By implementing access control measures, organizations can enforce security policies effectively, allowing for a tailored approach to who can access particular locations based on their roles, credentials, or other factors. Such systems can manage a range of entry points, integrating features like key cards, biometric scanners, and identification codes, enhancing overall security.

While monitoring entry points is a component of access control, it is not their sole purpose. Access control systems are designed to encompass a broader range of functionalities, including the management of movement within a facility, logging entries and exits, and providing alerts in case of unauthorized access attempts. Therefore, defining and controlling entrances and exits is a fundamental role that goes beyond mere monitoring, making it the most accurate choice.
