System and security administration is management and configuration of one or more computers with multiple operating systems, multiple hardware architectures, multiple software suites, together with the shared resources necessary, such as wired and wireless networks, to make them work effectively and securely. System administration requires an understanding of how computer systems work, an attention to detail, problem solving, people skills, security and planning. Computers which function as servers may run Unix-like systems, although others run proprietary software such as Novell, IBM or Microsoft.

This course provides students with a comprehensive understanding of the administration of computer systems and computer networks. Coverage includes system administration tools, security techniques, system initialisation, resource management, backups, performance measurement, network and security administration and ethical considerations. Students will develop and appraise documentation policy and disaster recovery procedures. Practical work requires use of Unix- like operating systems on dedicated Intel-architecture PCs or equivalent hardware and software.
