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

Integrating enterprise services, maintaining cybersecurity controls, and troubleshooting information networks transfer directly to administering civilian systems and networks.

How to prepare: Build a lab that integrates Active Directory with an email or collaboration service, then document configuration, security controls, and troubleshooting tests.

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.
  • Configure, monitor, and maintain email applications or virus protection software.
Civilian tools and software (examples)
