An access control list (ACL), with respect to a computer file system, is a list of permissions attached to an object.An ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects.Each entry in a typical ACL specifies a subject and an operation.n the 1990s the ACL and RBAC models were extensively tested and used to administrate file permissions. A filesystem ACL is a data structure (usually a table) containing entries that specify individual user or group rights to specific system objects such as programs, processes, or files.
