Before access control can happen in a physical security context, what must occur?

In the context of physical security, before access control can be successfully established, the identification and authentication of individuals seeking access must take place. Authentication is a critical component of the access control process, as it verifies the identity of a user after they have been identified. During this step, the system may require a form of evidence from the individual, such as a password, keycard, biometric data, or other methods, to confirm that they are indeed who they claim to be.

This authentication process ensures that only individuals with the right credentials can gain access to secured areas or systems. It creates a barrier against unauthorized access, thereby enhancing the overall security of the physical environment. By successfully authenticating an individual, organizations can effectively manage and enforce access control measures, ensuring that sensitive areas are protected from those who do not have permission to enter.
