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

Documented operating system administration, configuration monitoring, hard drive restoration, and replacement-device setup transfer directly to maintaining civilian computing environments.

How to prepare: Build a Linux practice environment and document a complete backup, restoration, and replacement-device configuration exercise.

What the civilian work involves
  • Maintain and administer computer networks and related computing environments, including computer hardware, systems software, applications software, and all configurations.
