SYSTEMS ADMINISTRATOR RESOURCES

 
A systems administrator (sysadmin) is an individual responsible for maintaining a multi-user computing system. Typical duties include: setting up user accounts; installing software (sometimes available system wide); allocating storage space to user accounts; and patching software. The following information sources have been compiled to assist Systems Administrators at Mason with their security duties.
