Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Computer Network Support Specialists

Installing and troubleshooting IP-based network nodes and associated network assets transfers directly to diagnosing civilian network faults.

How to prepare: Create a troubleshooting portfolio that records diagnostic tests, fault isolation, and fixes for a small practice network.

What the civilian work involves
  • Identify the causes of networking problems, using diagnostic testing software and equipment.
  • Document network support activities.
Civilian tools and software (examples)
  • Linux
  • Microsoft Windows

Network and Computer Systems Administrators

Operating network control centers and maintaining and reengineering network assets provides a foundation for civilian network administration.

How to prepare: Build a Linux administration lab and document a network configuration change, a backup, and a tested recovery.

What the civilian work involves
  • Maintain and administer computer networks and related computing environments, including computer hardware, systems software, applications software, and all configurations.
  • Perform data backups and disaster recovery operations.
  • Operate master consoles to monitor the performance of computer systems and networks and to coordinate computer network access and use.
Civilian tools and software (examples)
  • Linux
  • Microsoft Active Directory
