Purple Teaming ICS Networks: Part 3 of 3

**Executive Summary:** This article concludes a three-part series on ICS Purple Teaming, describing how coordinated Red and Blue team activity reduces operational risk through transparent communication, improves detection and validation of event collection in real time, and leverages operations knowledge to surface vulnerabilities. It outlines planning considerations (planned tactics/tools, detection methods, investigation tools, triage capabilities), emphasizes documenting each tactic and detection outcome (including PCAPs and event data), and recommends producing a final report that identifies capability gaps and provides remediation guidance.
