Network security specialists regulate access to various computer files and monitor file use to make sure that only appropriate people are accessing particular files.

They maintain and change employee information, ensure its confidentiality, and back up files to guarantee their safety in the event of network difficulties.

A network security specialist may also develop, implement, and test off-site systems that will continue to work in the event of on-site emergencies, such as power failures, fires, or floods.

Networking positions are likely to grow much faster than average through 2014 as more companies move from mainframe computers to client-server networks or from paper-based systems to automated record-keeping using networked databases.

Network security specialists should enjoy learning about new developments in the computer field and solving problems through the patient and persistent use of logic. In addition, they must be detail-oriented, stress-tolerant, and able to work independently as well as in a team environment.

In this rapidly changing field, job responsibilities vary from one position to the next, but all jobs require technical expertise to plan, implement, upgrade, and monitor a computer network’s information security measures.

Network security specialists must be able to design security architecture, such as firewalls and backup systems; audit the integrity of networked data; and identify and respond to possible threats and violations. Strong oral and written communication skills are also needed to develop security policies and provide employee awareness and training programs.

Because new technology and security strategies are constantly being introduced, network security specialists must keep their skills and knowledge up-to-date by reading, discussing new developments with others, and attending presentations, seminars, and training programs.

Most specialized network jobs require at least a bachelor’s degree in computer science or computer engineering. More specialized positions required an advanced degree. People with college degrees are more likely to handle the theoretical aspects of computer networking and to be promoted to management positions.

Network security specialists may work at any company or organization that uses computer networks in its business. These include banks, financial institutions, federal and state governments, universities, insurance companies, and other corporations that rely on networking. As smaller companies progressively move to the client-server model, job opportunities are likely to increase.
