CD-X Methodologies

The methodology of a Cyber Drill X outlines the systematic approach used to organize cyber drill effectively and successfully. It ensures that the drill is affordable, realistic, organized, and delivers measurable outcomes. A solid methodology aligns the drill with organizational objectives and enables participants to develop the skills and insights needed to respond effectively to cyber incidents.

CD-X divided the cyber drill methodologies to 5 main topics:

1. Sponsors
2. Setup
3. Brief
4. Play (execution)
5. Feedback (evaluate) a cybersecurity exercise.

Why This Methodology Matters

A well-structured methodology ensures that cyber drills are not ad hoc events but deliberate, impactful exercises. By following a clear methodology, organizations can:

• Test and strengthen their defenses.
• Foster a culture of preparedness and continuous improvement.
• Protect their operations, reputation, and stakeholders effectively.

1. Sponsors Come First

4. Play (Playtime) – Cyber drill execution

Methodology to Perform Play (Play-Time) During Cyber Drill Execution

The execution phase of a cyber drill, often called “play or play-time” is the centerpiece of the exercise. This phase tests the organization’s detection, response, and mitigation capabilities against a simulated cyber threat in real time. Below is a step-by-step methodology for the playtime phase to ensure an effective and structured execution:

4.1. Initiate the Scenario

Follow the scenario has been briefed during the briefing session.

• Purpose: Gradually introduce the simulated incident to reflect real-world attack dynamics.
• Steps:
  • Start with an initial event, such as suspicious activity in logs, a phishing email, or malware alert, to initiate the drill.
  • Let the team identify and escalate the issue naturally without excessive guidance.

Example:

• SOC receives an alert about unusual outbound traffic from a server, mimicking data exfiltration.

---

4.2. Observe Real-Time Reactions

• Purpose: Monitor how teams react to the unfolding scenario without intervening.
• Actions:
  • Detection Phase: Evaluate how quickly and effectively the incident is identified.
  • Escalation Phase: Track whether appropriate escalation steps are followed.
  • Coordination Phase: Assess communication among SOC, IT, legal, PR, and leadership teams.

Key Metrics:

• Time to detect and escalate the incident.
• Clarity and accuracy of communication.

4.3. Present Scenario Updates Dynamically

• Purpose: Add complexity to the simulation based on participants’ actions to mirror an evolving real-world threat.
• Steps:
  • Introduce new elements, such as spreading malware, ransom demands, or external media inquiries, to test adaptability.
  • Simulate responses from external entities like attackers or regulators, using a control team to role-play.

Example:

• After the initial alert, simulate attackers encrypting additional systems or releasing sensitive information.

4.4. Ensure Controlled Chaos

• Purpose: Mimic the high-pressure environment of a real attack without compromising safety.
• Techniques:
  • Use an isolated testing environment or simulated logs to avoid real-world impacts.
  • Allow room for errors while ensuring that the simulation stays on track.
  • Prevent over-guidance to maintain realism but step in if the drill veers off-course.

Example: If teams misuse actual tools that could disrupt operations, pause the drill to redirect efforts.

4.5. Encourage Decision-Making and Collaboration

• Purpose: Evaluate how effectively participants make decisions under pressure.
• Steps:
  • Force participants to make real-time decisions on containment, eradication, and recovery.
  • Monitor if team members adhere to pre-defined playbooks and escalate to leadership when appropriate.
  • Assess cross-department collaboration, particularly for non-technical roles like legal, HR, and public relations.

Example: SOC identifies ransomware on a critical server. Teams must decide: shut down the server immediately or isolate it first while notifying leadership.

4.6. Monitor Key Performance Metrics

• Purpose: Collect data to evaluate performance during the post-drill analysis.
• Metrics to Monitor:
  • Time to detect the incident.
  • Time to escalate the issue.
  • Containment and recovery timelines.
  • Effectiveness of internal and external communication.
  • Gaps in coordination between teams or playbooks.

Example Metric: SOC detected the incident within 15 minutes but took 2 hours to inform leadership due to communication bottlenecks.

4.7. Engage Control and Observation Teams

• Purpose: Ensure the drill is effectively monitored and controlled without interfering with participants’ actions.
• Roles:
  • Control Team: Introduces scenario updates, acts as the attackers, and adjusts the flow of the drill.
  • Observer Team: Records participant actions, notes deviations from expected processes, and collects performance data.

Best Practices:

• Use observers as silent participants who document actions and reactions without influencing the exercise.
• Use control team interventions sparingly to correct major deviations.

4.8. Handle Injects and Stress Points

• Purpose: Test participants’ ability to handle multiple issues simultaneously, as real incidents often involve overlapping complications.
• Examples of Injects:
  • Introduce a phishing email that appears during the main attack.
  • Simulate a regulatory request or media inquiry about the breach.

Goal: Evaluate how teams prioritize and handle parallel issues.

4.9. Facilitate Role-Playing

• Purpose: Add realism by simulating external interactions.
• Example Roles:
  • An attacker demanding a ransom.
  • A media outlet seeking comment.
  • A regulator requesting an immediate incident report.

Best Practices: Role-players should maintain professionalism and keep interactions within the scope of the drill.

4.10. End the Drill Gracefully

• Purpose: Ensure that the drill has a structured conclusion and transitions to evaluation.
• Actions:
  • Announce when the exercise is complete.
  • Begin immediate debriefs with participants to capture insights while events are fresh.
  • Transition into post-drill evaluation and lessons learned.

Example: End the drill after teams submit their containment and mitigation report or simulate achieving full recovery.

Summary of Playtime Focus Areas

1. Simulate scenarios realistically and dynamically.
2. Monitor team detection, decision-making, and communication.
3. Collect metrics on performance, including timing and adherence to protocols.
4. Engage control and observation teams for smooth execution and documentation.
