Access control refers to exerting control over who can interact with a resource, such as a door, turnstile, parking gate or elevator. It can be implemented through hardware, software, physical means or logical policies. There are two main types of access control: physical access security, which controls entry to physical resources; and computerized access control, which uses identification, authentication and authorization to control access to digital resources. Computerized access control also provides accountability and can be implemented through various access control models.
