Access control is a way of limiting access to a system or to physical or virtual resources. In computing, access control is a process by which users are granted access and certain privileges to systems, resources or information.
In access control systems, users must present credentials before they can be granted access. In physical systems, these credentials may come in many forms, but credentials that can’t be transferred provide the most security.
There are three factors that can be used for authentication:
- Something only known to the user, such as a password or PIN
- Something that is part of the user, such as a fingerprint, retina scan or another biometric measurement
- Something that belongs to the user, such as a card or a key
