Performing Purple Team Exercise

When to Use

Use this skill when:

• SOC teams need to validate that detection rules actually fire for the threats they target
• Red team assessments produced findings that need translation into detection improvements
• New detection tools or SIEM migrations require validation of detection coverage
• Analyst training requires hands-on experience with real attack techniques and SIEM responses
• Quarterly or semi-annual detection validation cycles are scheduled

Do not use for unannounced red team engagements — purple team exercises require explicit coordination between offensive and defensive teams with real-time collaboration.

Prerequisites

• Red team capability: internal team or contracted purple team operator
• Attack simulation tools: Atomic Red Team, MITRE Caldera, or C2 framework (authorized)
• SIEM access for real-time alert monitoring during exercise
• ATT&CK-mapped detection rule inventory with expected alert names
• Isolated test environment or approved production scope with change management approval
