User access rights

Overview
To restrict a legitimate user’s access to only those programs and files needed, organizations establish user access rights: allowable actions that can be assigned to a user or to groups of users. File and directory permissions are rules that are associated with a particular file or directory, regulating which users can access it &mdash; and the extent of their access rights. To avoid unintentionally giving a user unnecessary access to sensitive files and directories, an organization must give careful consideration to its assignment of rights and permissions.
