Access control lists

An access control list (ACL) policy is a set of actions, controls, or permissions. The ACL policy specifies the necessary conditions for a user or group to do operations on a resource.

ACL policy definitions are important components of the security policy established for a domain.

An ACL policy specifically determines what operations can be done on a resource, and who can do those operations. An ACL policy is made up of one or more entries that include user and group designations and either their specific permissions or rights.
