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

GCCS-M installation, configuration, repair, account setup, and basic disaster recovery directly overlap with civilian systems administration.

How to prepare: Build a Linux lab that demonstrates account creation, interface configuration, and recovery from a backup.

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

Database Administrators

Maintaining GCCS-M databases and establishing accounts provides a foundation for the maintenance and user-access aspects of database administration.

How to prepare: Create a practice database, assign different user access levels, and test a controlled database change.

What the civilian work involves
  • Modify existing databases and database management systems or direct programmers and analysts to make changes.
  • Specify users and user access levels for each segment of database.
  • Test changes to database applications or systems.
