When it comes to cybersecurity, preparation is key. Every SOC (Security Operations Center) team needs to be ready for real-world incidents, and one of the best ways to ensure this readiness is through incident response tabletop exercises.

Step 1: Setting the Objective

Before you dive into planning, you need a clear objective for your tabletop exercise. Without a focus, it’s easy to lose track of what you’re trying to achieve. Here are some common objectives that teams set for these drills:

  • Assess Communication Protocols: Ensuring that everyone knows who to contact and how to escalate an incident.
  • Test Incident Response Plan: Checking if your existing plan aligns with real-world scenarios.
  • Identify Gaps in Preparedness: Pinpointing weaknesses in technology, procedures, or knowledge.
  • Build Confidence in the Team: Giving SOC analysts and other team members the chance to practice without the pressure of a live incident.

Choose an objective that’s most relevant to your organization’s needs. It helps keep everyone aligned, from leadership to the SOC team members on the front lines.

Step 2: Designing the Scenario

This is where the exercise gets interesting. The scenario is essentially the “story” you’ll be guiding your team through, and it should be realistic enough to reflect actual threats your organization could face. Here are some popular tabletop exercise scenarios:

  • Phishing Attack: A user receives a phishing email that leads to credential theft and unauthorized access.
  • Ransomware Attack: A critical system is infected, and data is encrypted with a demand for payment.
  • Data Breach: Sensitive customer or company data is accessed or stolen.
  • Insider Threat: An employee or contractor with legitimate access misuses it, either intentionally or accidentally.

Make the scenario as detailed as possible, including timestamps and stages for the attack. For example, if you’re running a ransomware scenario, you could break it down into stages like “initial detection,” “encryption notice,” “contact with attacker,” and “containment measures.” These stages provide structure for the exercise, making it easier for team members to understand the timeline of events.

Step 3: Assembling the Right Participants

A successful tabletop exercise goes beyond just the SOC team. You need to include all relevant parties who would be involved in an actual incident response. Here’s who you should consider:

  • SOC Analysts and Engineers: They’re on the front lines, responsible for monitoring, detecting, and containing incidents.
  • IT and System Administrators: They handle critical infrastructure, like networks and servers, which are often affected in an incident.
  • Legal and Compliance: They ensure the organization’s response aligns with legal and regulatory requirements.
  • Communications/PR: They manage public and internal communication, which is essential in a data breach or ransomware attack.
  • Leadership: Including leadership ensures that decision-makers understand the complexity of incident response and the critical decisions that need to be made quickly.

Each team has a unique role in the incident response process. Bringing them all together during a tabletop exercise fosters understanding and collaboration.

Step 4: Setting the Stage for the Exercise

On the day of the exercise, create an environment where participants feel comfortable asking questions and testing out their ideas. Keep in mind, this is a practice session, not an exam. Here’s how to set the stage:

  • Brief the Team on Objectives and Rules: Start with a short briefing that goes over the exercise’s objectives, structure, and ground rules. Make it clear that mistakes are learning opportunities and that the goal is collaboration, not perfection.
  • Outline the Scenario’s Starting Point: Describe the initial situation and give participants any necessary background information. You might even provide them with a fake report or alert to make it feel more real.
  • Introduce the “Injects”: Injects are new pieces of information or challenges that you introduce during the exercise to add complexity. For example, an inject could be a new report that a user clicked a phishing link or that a server is unresponsive. These injects keep the exercise dynamic and realistic.

Step 5: Running the Exercise in Real-Time

This is where the team gets hands-on with the incident. You’ll guide them through the scenario, prompting them with questions, injecting new information, and keeping things moving. Here’s how to make this phase effective:

  • Ask Probing Questions: Encourage participants to think critically. Ask questions like, “What actions would you take next?” or “Who needs to be informed at this stage?” This pushes them to consider all aspects of the response.
  • Encourage Communication: Make sure that team members communicate with each other as they would in a real incident. For example, the SOC team should inform the communications team if they plan to contain the threat in a way that might impact systems.
  • Introduce Unexpected Twists: To keep everyone engaged, throw in surprises. For instance, you might add an inject where an additional phishing email goes out or where the attacker starts deleting files. This tests the team’s adaptability and their ability to handle multiple crises at once.

Keeping the exercise engaging is key. You want participants to stay focused and to treat the drill as if it’s real.

Step 6: Facilitating the Discussion

After the team has responded to the incident, hold a debrief session. This discussion is a chance to explore what went well, what could have been improved, and any lessons learned. Guide the discussion with questions like:

  • What were the first actions taken, and were they effective? This question helps assess if the initial response was appropriate or if the team needs more training on prioritizing actions.
  • Were there any breakdowns in communication? Effective communication is often the biggest challenge during incidents. If there were issues, try to understand why they happened and how they can be avoided in the future.
  • Did participants feel they had the information and tools they needed? Lack of access to information or tools can hinder response efforts. If anyone felt unprepared, it’s essential to address this.
  • What could we do differently next time? The goal is continual improvement. Encourage participants to suggest changes to policies, training, or tools that would make future responses smoother.

The debrief should be constructive and solution-oriented. Keep it positive, and focus on making incremental improvements.

Step 7: Documenting and Acting on Findings

After the debrief, document everything from the exercise — observations, challenges, recommended improvements, and feedback. This documentation will be valuable for two main reasons:

  • Creating a Record for Compliance: Many organizations, especially those in regulated industries, are required to demonstrate they have incident response training programs. The documentation serves as evidence of these efforts.
  • Improving the Incident Response Plan: Any gaps or weaknesses identified in the exercise should lead to actionable changes in the incident response plan, policies, or training. This might include updating procedures, investing in new tools, or scheduling follow-up training.

Use this information to refine your incident response plan. Every exercise should leave you better prepared than before, with clearer steps and more robust protocols in place.

Key Takeaways for Running Effective Tabletop Exercises

Running an effective tabletop exercise requires planning, engagement, and follow-through. Here are some quick takeaways:

  • Start with a Clear Objective: Whether it’s improving communication or testing a specific procedure, keep your focus clear.
  • Design Realistic Scenarios: Tailor the scenario to actual threats your organization might face.
  • Bring in All Relevant Teams: Include anyone who would be involved in a real incident, from IT to leadership.
  • Keep It Dynamic with Injects: Don’t let the exercise become stagnant. Introduce surprises to keep participants engaged.
  • Encourage Open Communication: This is a learning opportunity, so create an environment where people feel comfortable collaborating and sharing ideas.
  • Document and Improve: Use the exercise to identify weaknesses and refine your incident response approach.

Tabletop exercises are more than just drills — they’re opportunities to learn, adapt, and improve. By running regular and structured exercises, you’ll help your team gain confidence, respond faster, and better protect your organization from cyber threats.
