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

Analysis of persistent intrusions, malware, and forensic evidence directly supports civilian investigations of compromised systems and network intrusions.

How to prepare: Build a forensic case study in a lab that preserves a system image, reconstructs an intrusion from logs, and documents evidence-handling procedures.

What the civilian work involves

Analyze log files or other digital information to identify the perpetrators of network intrusions.
Conduct predictive or reactive analyses on security measures to support cyber security initiatives.
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
