Types of System Administrators

Generally, smaller companies employ one or a couple of system administrators to oversee the entire range of responsibilities of the organization. The circumstances differ in larger organizations, where there are a number of system administrators, each having specific responsibility.

The baseline or general system administrator is accountable for almost all portions of a computer network. Depending on the operating system with which they are well-versed, system administrators fall into two groups—those who know Unix-based operating systems like the Sun Solaris operating environment, and those who know Microsoft Windows operating systems and network environments. These days, a great majority of companies have come to require and acquire system administrators who have experience with the Linux operating system. Whatever their area of specialization, these administrators become the “go to” guys in regards to everything system and network related. They are the first line of defense in a networking high and low profile IT environments.

Network administrators manage the network, assign IP addresses to systems, servers and peripherals and ensure that the network runs picture perfect. It is important that they are able to program and properly administer the software that controls networks, and have in-depth knowledge of the various network protocols. Network administrators actively work with project managers, system administrators, configuration managers and others during the planning, designing and upgrading of networks.

Security administrators make sure the organization’s systems are secure. They may also keep a watch over employees for inappropriate network usage. Security administrators regularly keep themselves in the know about programs that can be used to attack or infect a network such as password cracking, viruses, algorithms, and other malicious applications. Nothing is impossible, and in those few cases where a violation cannot be prevented, the system administrator’s job is to isolate the occurrence, assess the damage, patch up the problem, submit the required reports and make certain that the system is well-prepared for possible future incidents.

Database administrators make sure information on the network is accurately saved and develop and implement appropriate storage systems based on the requirements of the organization. They also maintain proper backup schema and schedules, as well plan for disaster recovery by retaining backed up data off-site. This way, information that is considered critical to the company is not permanently lost.

The web-server administrator is the individual who maintains the actual web server so the Webmaster can administer the sites that are running on it. Web-server administrators
