Overview

A Cyberspace Warfare Operator employs offensive and defensive cyber tools, tactics, techniques, and procedures to integrate effects into warfighting functions. The operator emulates known adversary tactics through simulated exploitation or attacks on Department of Defense information systems, identifies unmitigated vulnerabilities, and searches for and responds to targeted adversary presence in friendly environments.

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.

Information Security Analysts

Experience identifying vulnerabilities through simulated attacks and searching for and responding to adversaries within defended networks transfers directly to security assessment and defensive analysis.

How to prepare: Build a security assessment portfolio in an isolated lab, documenting a simulated attack, the vulnerability it exposes, and a tested defensive mitigation.

What the civilian work involves

Perform risk assessments and execute tests of data processing system to ensure functioning of data processing activities and security measures.
Develop plans to safeguard computer files against accidental or unauthorized modification, destruction, or disclosure and to meet emergency data processing needs.

Civilian tools and software (examples)

Linux
Microsoft PowerShell
Python
