ACL (Access Control List)

Definition

An Access Control List (ACL for short) is a software technique with which operating systems and application programs can restrict access to data and functions. An ACL defines the extent to which individual users and system processes have access to certain objects (such as services, files, registry entries, etc.).

In contrast to simple access rights, ACLs are more finely adjustable. In Windows, for example, ACLs can be used to assign different rights for a file for several users and several groups, whereas in Linux, simple access rights can only be used to assign rights for one user, one group and the "rest of the world".
