Purple Teaming ICS Networks: Part 1 of 3

This blog (part one of a three-part series) explains ICS Purple Team engagements—collaborative, grey-box assessments that pair Red and Blue teams (including operations, engineering, and IT) to improve detection, reduce operational risk, and produce better remediation recommendations. It defines ICS assessment types (white-, grey-, black-box), outlines Red/Blue roles during Purple Teaming, lists benefits and limitations, and advises that Purple Teaming is not always suitable for less mature organizations or those seeking to minimize findings.
