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

Communications monitoring, fault isolation, service restoration, and user support transfer directly to diagnosing and resolving network problems.

How to prepare: Build a small practice network, introduce connectivity and permission faults, and document the diagnostic steps and successful fixes.

What the civilian work involves
  • Configure security settings or access permissions for groups or individuals.
  • Identify the causes of networking problems, using diagnostic testing software and equipment.
  • Document network support activities.
Civilian tools and software (examples)
  • Microsoft Windows
  • Microsoft Windows Server

Network and Computer Systems Administrators

Operating and maintaining information systems, managing accounts and permissions, and restoring failed equipment align with systems administration duties.

How to prepare: Set up a Windows Server and Active Directory lab to practice account provisioning, permission changes, and system performance monitoring.

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.
