Encyclopedic overview
Common physical security access control with a finger print A sailor checks an identification card (ID) before allowing a vehicle to enter a military installation.
In physical security and information security, access control (AC) is the action of deciding whether a subject should be granted or denied access to an object (for example, a place or a resource). The act of accessing may mean consuming, entering, or using. It is often used interchangeably with authorization, although the authorization may be granted well in advance of the access control decision.
