SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

SOC teams often deploy detection rules without verifying they actually fire against real attack techniques, leaving silent coverage gaps. This Skill structures a collaborative purple team exercise where red team attack execution and blue team SIEM monitoring happen in real time, so every detection rule is proven or remediated on the spot.

Core Features & Use Cases

  • ATT&CK-Mapped Test Planning: Builds a technique-by-technique test matrix mapping MITRE ATT&CK IDs to test tools, expected alerts, and detection latency metrics.
  • Guided Execution and Monitoring: Provides Atomic Red Team commands for technique execution alongside Splunk SPL queries for real-time blue team detection tracking.
  • Same-Day Gap Remediation: Walks through writing new detection rules for missed techniques and re-testing them during the exercise, then generates a coverage report.
  • Use Case: A SOC runs a quarterly FIN7-scenario exercise across a test VLAN, discovers LSASS access and C2 beaconing are undetected, builds the missing Splunk rules during the session, and raises detection coverage from 73% to 93%.

Quick Start

Plan and run a purple team exercise that validates my detection rules against FIN7 techniques using Atomic Red Team and my SIEM.

Frequently Asked Questions about performing-purple-team-exercise

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run a purple team exercise to validate detection rules?▼

Define an ATT&CK-mapped test plan listing techniques, tools, and expected alerts, then execute each technique with Atomic Red Team while the blue team monitors the SIEM in real time. Record detection status and latency per technique, build rules for gaps, and re-test immediately.

What tools are used for adversary emulation in purple teaming?▼

Atomic Red Team provides small per-technique tests mapped to ATT&CK, while MITRE Caldera automates multi-step attack chains. Vectr, Prelude Operator, and AttackIQ support exercise tracking and continuous breach and attack simulation.

How do I measure detection latency during attack simulation?▼

Detection latency is the time between technique execution and SIEM alert generation. In Splunk, subtract the original event time from the alert time and record the result per technique in the exercise results matrix.

Can purple team exercises run in a production environment?▼

Yes, but only within an approved scope such as a designated VLAN with change management authorization and excluded critical systems. The skill recommends isolated test endpoints and explicit CISO approval before execution.

When should I not use a purple team exercise?▼

Do not use this approach for unannounced red team engagements, since purple teaming requires explicit real-time coordination between offensive and defensive teams. Stealth-based assessments need a separate red team methodology.
