Physical access control limits access to campuses, buildings, rooms and physical IT assets. Even though the general safety computation is proven undecidable [1], practical mechanisms exist for achieving the safety requirement, such as safety constraints built into the mechanism. Authentication is necessary to ensure the identity isnt being used by the wrong person, and authorization limits an identified, authenticated user from engaging in prohibited behavior (such as deleting all your backups). Access control models bridge the gap in abstraction between policy and mechanism. In addition to the authentication mechanism (such as a password), access control is concerned with how authorizations are structured. Most organizations have infrastructure and procedures that limit access to networks, computer systems, applications, files and sensitive data, such as personally identifiable information and intellectual property.
