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

ITN experience building, configuring, maintaining, and troubleshooting networks and conducting backups and restores directly supports network and systems administration.

How to prepare: Build a civilian administration lab using Linux or Microsoft Active Directory and document a network fault diagnosis and a successful 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 Engineers

ITN experience implementing defensive controls, monitoring network systems, and assessing threats and vulnerabilities transfers to security engineering work.

How to prepare: Create an isolated security lab and document a vulnerability scan, a corrective security control, and a follow-up assessment of that control.

What the civilian work involves
  • Coordinate monitoring of networks or systems for security breaches or intrusions.
  • Assess the quality of security controls, using performance indicators.
  • Scan networks, using vulnerability assessment tools to identify vulnerabilities.
Civilian tools and software (examples)
  • Linux
  • Bash
  • Microsoft PowerShell
