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 User Support Specialists

Computer installation, limited field maintenance, incident processing, and user interaction transfer directly to desktop and user support.

How to prepare: Prepare a troubleshooting portfolio showing an equipment setup, a diagnosed hardware or software problem, and the steps used to resolve a user incident.

What the civilian work involves
  • Set up equipment for employee use, performing or ensuring proper installation of cables, operating systems, or appropriate software.
  • Read technical manuals, confer with users, or conduct computer diagnostics to investigate and resolve problems or to provide technical assistance and support.
  • Install and perform minor repairs to hardware, software, or peripheral equipment, following design or installation specifications.
Civilian tools and software (examples)
  • Linux
  • Microsoft Active Directory

Network and Computer Systems Administrators

Military administration of computers, servers, routers, and switches directly overlaps with maintaining civilian computing environments.

How to prepare: Build a small server and network lab, then document configuration, troubleshooting, and a tested backup restoration.

What the civilian work involves
  • Maintain and administer computer networks and related computing environments, including computer hardware, systems software, applications software, and all configurations.
  • Perform data backups and disaster recovery operations.
  • Diagnose, troubleshoot, and resolve hardware, software, or other network and system problems, and replace defective components when necessary.
Civilian tools and software (examples)
  • Linux
  • Microsoft Active Directory
  • Bash

Information Security Analysts

Military cybersecurity functions and network security policy implementation provide a foundation for civilian security analysis and control testing.

How to prepare: Complete a lab-based risk assessment that tests system security settings and documents findings and corrective actions.

What the civilian work involves
  • Develop plans to safeguard computer files against accidental or unauthorized modification, destruction, or disclosure and to meet emergency data processing needs.
  • Perform risk assessments and execute tests of data processing system to ensure functioning of data processing activities and security measures.
  • Modify computer security files to incorporate new software, correct errors, or change individual access status.
Civilian tools and software (examples)
  • Linux
  • Microsoft PowerShell

Training & Development

Choose credentials for your target role. COOL funding markers describe program listings, not a guarantee of eligibility or funding.

Getting Started

  • CompTIA A+ · Funded · Promotion points

    Support the user-support path with a foundational certification. CompTIA recommends 12 months of hands-on IT support experience; earning A+ requires both Core 1 and Core 2 exams from the same version.

    For: Computer User Support Specialists

  • CompTIA Network+ · Funded · Promotion points · STAR

    Support preparation for network administration responsibilities. CompTIA recommends A+ certification and 9 to 12 months of junior network administration or network support experience, rather than requiring them.

    For: Network and Computer Systems Administrators

  • CompTIA Security+ · Funded · Promotion points · STAR

    Develop core IT security knowledge for the security analyst path. CompTIA recommends Network+ and two years in a security or systems administrator role as preparation, not mandatory eligibility.

    For: Information Security Analysts
