What is the main objective of access control within security?

The primary objective of access control within security is to restrict unauthorized entry. This fundamental aspect of security ensures that only individuals who have been granted permission can enter specific areas or access certain resources. Access control mechanisms can utilize various methods, including physical barriers like locks and gates, electronic systems such as key cards or biometrics, and policies defining who has access to what.

This approach not only protects sensitive areas or information from intruders but also helps maintain a safe and secure environment for authorized personnel. By effectively managing who can enter a facility or area, access control plays a critical role in overall security strategy, safeguarding against theft, vandalism, and other security breaches.

While monitoring staff presence, ensuring all doors are locked, and managing employee schedules might be relevant tasks within a security framework, they serve secondary roles in relation to access control's main goal of limiting entry to those who are not authorized.
