  • Active defense and adversary eradication planning
  • Critical cyber asset countermeasure recommendations

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.

Digital Forensics Analysts

Military forensic analysis, persistent-threat intrusion analysis, and adversary eradication experience directly support civilian investigations of compromised systems.

How to prepare: Build a lab case that preserves a system image and analyzes intrusion logs, documenting evidence handling against the legal policies and procedures of a target employer.

What the civilian work involves
  • Adhere to legal policies and procedures related to handling digital media.
  • Analyze log files or other digital information to identify the perpetrators of network intrusions.
  • Create system images or capture network settings from information technology environments to preserve as evidence.
Civilian tools and software (examples)
  • Linux
  • Microsoft PowerShell
  • Splunk Enterprise
