According to the U.S. Bureau of Labor Statistics, employment of network and computer systems administrators is expected to increase by 27 percent by 2016. This growth translates into a need for systems administrators who can help organizations use technology to communicate with employees, clients, and consumers. Demand for computer security specialists will grow as businesses and government continue to invest heavily in “cyber security,” protecting vital computer networks and electronic infrastructures from attack. The information security field is expected to generate many new systems administrator jobs over the next decade as firms across all industries place a high priority on safeguarding their data and systems.
