The Purple Team Operator's Handbook

by Joseph Haynes

Completing the Operator's Handbook trilogy, the Purple Team edition bridges the gap between offense and defense by providing a structured methodology for adversary emulation and detection validation. Joseph Haynes describes how to plan and execute purple team exercises that produce measurable improvements in security posture. The book covers selecting adversary profiles based on threat intelligence, mapping emulation plans to ATT&CK techniques, executing controlled attack simulations, and validating that detections fire correctly. Each chapter includes worksheets for tracking detection coverage, templates for reporting results to stakeholders, and metrics for measuring defensive improvement over time.
