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

Administering and securing Windows and Linux systems, monitoring network activity, and performing Tier 2 corrective actions directly overlap with civilian systems administration.

How to prepare: Build a Windows and Linux lab and document a troubleshooting exercise that diagnoses a network fault, restores service, and verifies security settings.

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.
