The access control system that can incorrectly accept an access attempt from an unauthorized user is likely a password-based authentication system.
Password-based authentication systems rely on users entering a correct username and password combination to gain access to a system or resource. If an unauthorized user is able to guess or obtain the correct credentials, they may be able to gain access. This can happen if the system does not have appropriate security controls, such as account lockouts or strong password requirements.
Biometric-based authentication systems use unique physical or behavioral characteristics, such as fingerprints or voice recognition, to verify a user's identity. These systems are generally considered more secure than password-based systems because the biometric characteristics are difficult to fake or duplicate. However, there is still a possibility that an unauthorized user could gain access if they are able to replicate the biometric characteristic (for example, by creating a fake fingerprint).
Location-based authentication systems rely on a user's physical location to verify their identity. For example, a system may only allow access from a specific building or geographic location. However, there is still a possibility that an unauthorized user could gain access if they are able to spoof their location.
Certificate-based authentication systems use digital certificates to verify a user's identity. These certificates are issued by a trusted authority and are used to verify the user's identity. They are generally considered more secure than password-based systems because they are difficult to replicate or steal.
In summary, the access control system reviewed by the auditor is most likely a password-based authentication system.
