In computing, permissions (often called "privileges," "access rights" or just "rights") are rules associated with objects on a computer or network. Permissions determine which objects can access which objects, and to what extent.

For example, file permissions are rules placed on a filesystem object defining which accounts are allowed to access the object, and what actions those accounts can take on the object, such as read, write and/or delete.
