A tabletop exercise (TTX) is a role-playing activity where players respond to simulated cybersecurity scenarios presented by facilitators to assess their incident response preparedness. TTXs allow organizations to align their teams and processes before an actual crisis, highlighting potential vulnerabilities and deficiencies in their disaster recovery plans. 

These tabletop exercises provide hands-on training to evaluate overall incident response capabilities, clarify roles and responsibilities during a security incident, and validate incident response playbooks and trainings.

Planning a Tabletop Exercise 

The first step in planning an effective tabletop exercise (TTX) is to set a clear and specific objective statement that defines the goals of the exercise and provides a framework for scenario development and evaluation. Identify the intended audience, whether it's a larger-scale exercise for the entire organization or a smaller subset focused on specific response procedures. 

Key Planning Steps

1. Create Discussion Questions: Develop discussion questions that will lead the participants through a role-playing game-like environment, focusing on the specific objective. 

2. Allocate Time: Set aside enough time for the tabletop exercise, typically 2-8 hours, to allow for active participation and discussion. 

3. Define Roles and Responsibilities: At the start of the exercise, clearly define the purpose, explain the process, and clarify the roles and responsibilities of the participants, facilitator, and observers. 

4. Assemble the Team: Gather a team of participants, facilitator, evaluators, and observers to run the exercise. 

5. Design the Scenario: Craft the scenario based on identified cyber threats and vulnerabilities, and include some curveball details to keep participants on their toes. Ensure the exercise tests human and managerial factors, not just technical defenses. 

6. Involve Key Stakeholders: Involve the Crisis Management Team (CMT), including representatives from legal, HR, operations, communications, and cybersecurity. 

7. Set Clear Objectives: Establish clear objectives, get everyone on board, make the exercise concise and engaging, and ensure it is a positive experience for the participants. 

8. Identify Gaps: Use the exercise to identify gaps in the team, such as lack of clear leadership, and incorporate absences of key personnel into the scenario. 

9. Facilitate Note-taking: Utilize a shared document for real-time note-taking and feedback during the exercise. 

10. Avoid Common Mistakes: Ensure the Incident Response Plan is on hand, contact lists are up-to-date, and key stakeholders are properly notified before news breaks. 

Exercise Objectives 

Common objectives for cybersecurity TTXs include: 

• Exploring and addressing cybersecurity challenges 

• Defining/refining participants' roles and responsibilities 

• Building relationships among stakeholders 

• Increasing cybersecurity awareness 

• Identifying enhancements needed in incident response plans

Participant Roles 

During the TTX, players typically play their own roles (e.g., CEO, IT lead, communications rep). Facilitators present information that may seem innocuous but could signal a serious issue, and the goal is to work as a team to identify and address problem areas. Roles in a TTX include players/participants, observers, facilitators, and note-takers. 

Facilitators should encourage 'thinking out loud' to reduce tension and support each other in identifying gaps in the team. It's important to ensure all players have a chance to participate and to supplement full TTX with shorter discussions. 

Conducting the Exercise 

During the exercise itself, it's crucial to encourage an open and collaborative environment. "Thinking out loud" should be promoted to reduce tension and foster mutual support by asking clarifying questions. Incorporating absences of key personnel into the scenario ensures that all players have an opportunity to participate and contribute. 

Real-time Note-taking 

Maintaining a shared document for real-time note-taking during the exercise is essential. This not only captures valuable insights and observations but also keeps the atmosphere friendly and supportive. Facilitators should encourage players to "think out loud" and ask clarifying questions, reducing tension and promoting a collaborative spirit. 

Flexible Formats 

Tabletop exercises need not be large-scale productions. They can be as concise as a 10-minute discussion, allowing organizations to regularly assess their preparedness. However, repetition is a key aspect, as it enables organizations to continuously improve their response capabilities. 

Measuring Effectiveness 

Measuring activities during a TTX is critical to determine how well the plans are working, identify areas for improvement, and develop strategies to address plan weaknesses. This evaluation process is crucial for enhancing overall incident response preparedness. 

After-Action Reporting 

Conducting the 'Hot Wash'

Immediately after the tabletop exercise, conduct a 'hot wash' review session to identify what went well, find best practices, and gather suggestions for improvements from the participants. This debrief session allows for a candid discussion while the experience is still fresh in everyone's minds. 

Summarizing and Proposing Improvements 

Summarize the exercise, highlight best practices, and propose an improvement plan based on the hot wash feedback. Develop a plan to implement the improvements and solutions identified during the tabletop exercise. Incorporate feedback from the hot debrief and ensure recommendations are implemented and tested in subsequent exercises. 

Updating Cybersecurity Plans 

Incorporate lessons learned into the Incident Response Plan and other policies after the tabletop exercise. Identifying deficiencies in business plans and incident response plans is a critical aspect of tabletop exercises, and addressing these deficiencies can improve overall preparedness. 

Post-TTX Evaluation 

Post-TTX evaluation provides an opportunity to identify areas where additional training, support, or changes to processes and procedures may be required. Repeat the cycle, starting again with assembling the team, to continuously improve the organization's cybersecurity preparedness. 

After-Action Report / Improvement Plan (AAR/IP) 

The After-Action Report / Improvement Plan (AAR/IP) aligns exercise objectives with preparedness doctrine, including the National Preparedness Goal and related frameworks. It covers the following sections: 

1. Exercise Overview 

2. Analysis of Exercise Objectives 

3. Improvement Plan 

The AAR/IP template provided covers 4 exercise objectives and their associated core capabilities, including: 

• Planning 

• Public Information and Warning 

• Operational Coordination 

• Intelligence and Information Sharing

• Interdiction and Disruption 

• Screening/Search/Detection 

• Forensics and Attribution 

• Access Control and Identity Verification 

• Cybersecurity 

The AAR/IP template provides a structured format for documenting strengths, areas for improvement, references, analysis, and recommendations for each objective. 

Improvement Plan 

The Improvement Plan appendix outlines a tabular format for tracking corrective actions, capability elements, responsible organizations, and timelines. It lists the issues/areas for improvement, the corrective actions, the primary responsible organization, the organization's point of contact, start dates, and completion dates. 

Comprehensive After Action Report Kit 

The content provides a 'Comprehensive After Action Report and Improvement Plan' kit to help with creating the perfect report after a cybersecurity TTX. The kit helps with practicing debrief sessions, empowering forensic teams, documenting exercise results, improving policies and procedures, and showcasing the team's effectiveness. 

Conclusion 

The ability to effectively respond to cybersecurity incidents is a critical aspect of maintaining organizational resilience. Conducting tabletop exercises is a valuable approach to proactively identify vulnerabilities, validate incident response plans, and enhance overall preparedness. By following the best practices outlined in this article, organizations can maximize the impact of their TTXs, fostering collaboration, identifying gaps, and continuously improving their cybersecurity readiness.
