Nearly all applications that deal with financial, privacy, safety, or defense include some form of access (authorization) control.

These permissions range from full control to read-only to access denied. When it comes to the various operating systems (i.e., Windows, Linux, Mac OS X), the entries in the ACLs are named access control entry, or ACE, and are configured via four pieces of information: a security identifier (SID), an access mask, a flag for operations that can be performed on the object and another set of flags to determine inherited permissions of the object. As systems grow in size and complexity, access control is a special concern for systems that are distributed across multiple computers.
