Purple Team Assessment Methodology

What is Purple Team Assessment?

 

Purple Team Assessment is a collaborative cybersecurity methodology that integrates the offensive tactics of a Red Team with the defensive strategies of a Blue Team to enhance an organization’s overall security posture. Unlike traditional penetration testing, which focuses solely on identifying vulnerabilities, or Red Team Assessments, which simulate adversarial attacks in isolation, Purple Team Assessments emphasize real-time collaboration between attackers and defenders. This approach involves simulating real-world attacks while working closely with the organization’s security team to identify gaps, optimize detection, and improve response capabilities. The goal is to foster knowledge sharing, strengthen defenses, and build resilience against sophisticated cyber threats through a hands-on, interactive process.

Purple Team Assessments are particularly effective for organizations seeking to mature their security operations, improve incident response, or align their defenses with advanced threat scenarios. By combining offensive and defensive perspectives, this methodology delivers actionable insights and measurable improvements in a controlled, collaborative environment.

 

Purple Team Methodology and MITRE ATT&CK Framework

 

Our Purple Team Assessments are structured around the MITRE ATT&CK Framework, a comprehensive knowledge base of adversary tactics, techniques, and procedures (TTPs) derived from real-world observations. MITRE ATT&CK provides a standardized approach to simulate, document, and analyze attacker behaviors, ensuring our assessments are aligned with the latest threat intelligence. The Purple Team methodology leverages MITRE ATT&CK to create a dynamic, iterative process that includes:

​

• Reconnaissance (TA0043): Simulating information-gathering techniques, such as OSINT or network enumeration, with Blue Team input to improve monitoring of reconnaissance activities.

• Initial Access (TA0001): Testing entry points like phishing or exploiting misconfigured services, followed by Blue Team analysis to enhance detection rules.

• Execution (TA0002): Deploying malicious payloads or scripts, with real-time collaboration to tune endpoint detection and response (EDR) systems.

• Persistence (TA0003): Establishing persistent access through techniques like registry modifications, with Blue Team guidance to improve logging coverage.

• Privilege Escalation (TA0004): Exploiting vulnerabilities to gain elevated access, paired with Blue Team efforts to strengthen access controls.

• Defense Evasion (TA0005): Bypassing defenses using obfuscation or anti-forensic techniques, with collaborative tuning of intrusion detection systems (IDS).

• Credential Access (TA0006): Attempting credential theft via keylogging or dumping, followed by Blue Team recommendations for credential protection.

• Discovery (TA0007): Mapping the environment to identify assets, with Blue Team input to enhance network visibility.

• Lateral Movement (TA0008): Moving across systems using techniques like pass-the-hash, with Blue Team efforts to improve segmentation and monitoring.

• Collection (TA0009): Gathering sensitive data, followed by Blue Team strategies to protect data at rest and in transit.

• Exfiltration (TA0010): Extracting data covertly, with Blue Team collaboration to strengthen data loss prevention (DLP) controls.

• Command and Control (TA0011): Establishing C2 channels, with Blue Team tuning to detect anomalous network traffic.

• Impact (TA0040): Simulating disruptive actions like ransomware, with Blue Team input to improve recovery processes.

 

Each phase is executed in close coordination with the Blue Team, with Red Team members explaining attack techniques, demonstrating exploits, and providing immediate feedback. This iterative process ensures that vulnerabilities are not only identified but also addressed through optimized tools, processes, and team skills, all mapped to MITRE ATT&CK for clarity and repeatability.

 

Red Team vs. Purple Team Approaches

 

We offer both Red Team and Purple Team methodologies for penetration testing, allowing organizations to choose the approach that best suits their needs:

​

Purple Team Approach:

​

• Objective: Enhance security through collaboration between Red Team (attackers) and Blue Team (defenders), focusing on real-time knowledge transfer and process improvement.

• Execution: The Red Team performs MITRE ATT&CK-aligned attacks while working closely with the Blue Team to explain techniques, demonstrate exploits, and optimize defenses. This includes live attack simulations, workshops, and debriefs to improve detection, response, and mitigation.

• Benefits: Accelerates security maturity by combining offensive and defensive insights, enhances team skills, and optimizes security tools like SIEM, EDR, or firewalls.

• Ideal For: Organizations aiming to build or mature their security operations, improve incident response, or align defenses with MITRE ATT&CK.

​

Red Team Approach:

​

• Objective: Simulate a real-world adversary with minimal prior knowledge (black-box or gray-box testing) to test the organization’s defenses in a stealthy, adversarial scenario.

• Execution: The Red Team operates independently, using MITRE ATT&CK-aligned TTPs to infiltrate systems, evade detection, and achieve objectives (e.g., data exfiltration). The Blue Team is unaware of attack details, mimicking a real-world scenario.

• Benefits: Provides a realistic test of detection and response capabilities, uncovers blind spots, and validates the organization’s resilience against advanced threats.

• Ideal For: Organizations with mature security programs seeking to stress-test their defenses or meet regulatory requirements for adversarial simulation.

 

Both approaches leverage the MITRE ATT&CK Framework to ensure structured, measurable, and repeatable testing. The Purple Team methodology stands out for its collaborative nature, making it ideal for organizations seeking to actively involve their security teams in the testing process.

Value to Your Business

​

The Purple Team Assessment methodology delivers measurable improvements to your organization’s security posture by fostering collaboration and aligning defenses with real-world threats. Key benefits include:

​

• Optimized Detection and Response: Identify and address gaps in monitoring, logging, and incident response through real-time collaboration.

• Enhanced Team Capabilities: Train your Blue Team with hands-on exposure to MITRE ATT&CK-based attack techniques and mitigation strategies.

• Improved Security Tools: Fine-tune SIEM, EDR, IDS, or other tools to maximize their effectiveness against advanced threats.

• Regulatory Compliance: Meet standards (e.g., NIST 800-53, ISO 27001) requiring advanced security testing and process improvement.

• Proactive Resilience: Build a stronger, more adaptive security posture capable of countering sophisticated cyber threats.

 

This methodology is critical for organizations looking to mature their security operations, foster collaboration, or prepare for advanced threat scenarios.
