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.

Network and Computer Systems Administrators

System administration, networked-system troubleshooting, activity monitoring, and security-policy enforcement transfer directly to maintaining civilian computing environments.

How to prepare: Build a Linux or Microsoft Active Directory lab and document how you configure access, diagnose a network fault, and restore a backup.

What the civilian work involves
  • Maintain and administer computer networks and related computing environments, including computer hardware, systems software, applications software, and all configurations.
  • Diagnose, troubleshoot, and resolve hardware, software, or other network and system problems, and replace defective components when necessary.
  • Operate master consoles to monitor the performance of computer systems and networks and to coordinate computer network access and use.
