Authentication is the first line of defense in your access control system. It verifies that a person or device is truly who they claim to be before granting entry. This can be done through:
Something you know – passwords, PIN codes, or security questions.
Something you have – keycards, mobile credentials, smart tokens, or one-time passcodes.
Something you are – biometric identifiers like fingerprints, facial recognition, or retina scans.
The stronger the authentication process, the harder it is for unauthorized individuals to gain access—keeping your systems, data, and premises secure.
Once a person or device is authenticated, authorization determines what they can access and what actions they can take. Authorization is like the rules of the building—it makes sure that:
Employees can enter the areas they need for their job, but not high-security zones.
Guests have temporary access that automatically expires.
System users can only view, edit, or delete data according to their role.
This process is controlled through predefined permissions and policies. The goal is to provide the right access to the right people at the right time—while preventing misuse or breaches.
