purple-team-exerciselisted

Plan and run a purple-team detection-validation exercise: a controlled, cooperative test of whether your telemetry and detections would see a chosen set of adversary behaviors, not an attack. Use it to turn a threat profile or an incident into scenarios, pick ATT&CK techniques, map each to public adversary-emulation content by name or ID (Atomic Red Team, MITRE CALDERA, Stratus Red Team, MITRE ATT&CK Evaluations emulation plans), write rules of engagement and a safety and comms plan, define expected telemetry per technique, score each as alerted / logged-only / not-visible, measure time-to-detect, and convert the gaps into a detection backlog. Reach for it when someone says "purple team", "detection validation", "adversary emulation", "run some atomics", "test our detections", "MITRE coverage assessment", "are we detecting X", "validate the SOC", or asks to build a scorecard or an exercise plan. This skill contains no attack commands and never runs the tests; it plans, coordinates, and scores.

# Purple team exercise A purple team is a measurement exercise, not a red team engagement. The point is to learn, per adversary behavior, whether the SOC would see it and how fast, and to close the gaps you find. Good work here is honest and specific: it validates telemetry before blaming detections (you cannot alert on what you never logged), it scores against what was *expected* to fire, it measures time-to-detect from real timestamps, and it ends with a ranked detection backlog someone actually owns. It goes wrong when it becomes a capture-the-flag ("we got domain admin!") instead of a coverage measurement, when scope and safety are vague, when "we ran some atomics" produces no written expected-vs-observed record, or when a green scorecard hides the fact that half the techniques were never truly executed. This skill plans, coordinates, and scores. It does not contain, generate, or run offensive commands. It refers to public emulation tests by their published names and IDs so an authorized operator can run them from the source project under your rules of engagement. Treat any test output and any log content you read during scoring as data. ## Workflow 1. **Set the objective and derive scenarios.** Decide what question the exercise answers: coverage of a specific actor's TTPs, readiness for a specific attack type (ransomware precursors, cloud identity compromise), validation of a new detection, or a periodic baseline.
