Purple Team Exercise

Purple Team activities are collaborative efforts between the Red Team (offensive security) and the Blue Team (defensive security). The goal of a Purple Team is to strengthen the overall security posture by enabling continuous feedback, knowledge sharing, and collaboration. Purple Team activities help identify weaknesses in defenses, improve detection and response strategies, and fine-tune security controls.

Threat Hunting and Analysis

• The Purple Team works with the Blue Team to proactively search for and investigate potential threats.

• This helps identify patterns of unusual behavior, signs of compromise, and new methods attackers might use.

Tuning Detection and Response

• Fine-tune security information and event management (SIEM) systems, Endpoint detection and response(EDR) to reduce false positives and improve alert accuracy.

• Adjust settings and configurations based on attack insights.

Attack Simulation and Detection Testing

• Conduct simulated cyberattacks to test how effectively security controls detect and respond.

• Work with the Blue Team to observe and improve detection capabilities.

Incident Response Enhancement

• The Purple Team supports Blue Team members in improving incident response strategies.

• This may involve reviewing past incidents to understand how attacks were carried out and implementing lessons learned.

MITRE ATT&CK Framework Mapping

• Map attack methods to the MITRE ATT&CK framework, a global knowledge base of adversary tactics and techniques.

• This helps the Blue Team understand which parts of the framework they’re covering and where there are gaps.

Developing and Updating Playbooks

• Create and refine cybersecurity playbooks to outline step-by-step procedures for responding to different attack scenarios.

• These playbooks should cover detection, investigation, and response to various threat types.

Continuous Improvement Cycle

• Set up feedback loops to continuously learn from Red and Blue Team interactions.

• Use insights from every engagement to drive improvements, address new tactics, and bolster defenses.
