Category:Unix security software
Unixes have a multi-tier security that permits user root any system-wide changes. Regular users can be limited: where they can save files, what hardware they can access, their memory usage, applications, disk usage (quota), and the range of priority settings they can apply, can all be specified to provide sufficient freedoms. If necessary they must become root. (See su or sudo). There are also group accounts management, and file and directory permissions.
