Ransomware tabletop exercises help organisations prepare for and respond to ransomware threats.
Pre-exercise preparation, in-exercise collaboration, and post-exercise debriefing by an information security expert are essential components of a successful exercise.
Integrating compliance with relevant regulations and proactive defence measures into the exercise is necessary for effective preparedness and cyber resilience.
What is a ransomware tabletop exercise?
A ransomware tabletop exercise is a simulated cyber-attack scenario designed to assist organisations in preparing and responding to ransomware threats. Participating in these tabletop exercise scenarios enables technical and administrative personnel to enhance their knowledge of cyber threats and their roles in responding to ransomware incidents. Representatives from all departments and business levels should be included in a ransomware tabletop exercise for optimal results, as it helps prepare the organisation for various cyber threats, similar to how organisations prepare for natural disasters.
A typical ransomware tabletop exercise includes:
Stakeholders and representatives from departments such as security, IT, legal, human resources, and public relations
An information security professional as a facilitator
Discussion-based tabletop exercises to replicate a ransomware attack scenario
Testing response capabilities
Identifying areas for improvement
Ransomware readiness assessment
A ransomware readiness assessment is a self-assessment process based on a tiered set of practices to evaluate an organisation’s preparedness to defend against ransomware attacks, ultimately improving cyber resilience. The effectiveness of a ransomware readiness assessment can be determined by assessing factors such as:
Recognition of vulnerabilities
Assessment of existing security measures
Formation of strategies
Comprehension of risks
Evaluation of incident response capabilities
Conducting a ransomware readiness assessment at least once a year is advisable; however, the frequency may vary depending on the organisation’s risk profile and industry standards.

Organisations in high-risk sectors, including those prone to natural disasters or those that have recently suffered security incidents, such as physical security breaches, might need to conduct assessments regularly to maintain readiness and ensure proper implementation of security protocols.
Why conduct a ransomware readiness assessment?
A ransomware readiness assessment is beneficial in identifying potential vulnerabilities and enhancing defences against ransomware attacks, preparing organisations to respond to such attacks effectively. Organisations can recognise potential weaknesses by conducting a ransomware readiness assessment, evaluating incident response procedures, and minimising disruption and downtime. These assessments encourage participants to actively improve their organisation’s cybersecurity defences.
A ransomware readiness assessment presents multiple benefits for enhancing cybersecurity defences, including:
Identifying vulnerabilities and weaknesses in security posture
Evaluating incident response capabilities
Pinpointing areas at the highest risk for attack
Organisations can mitigate the risk of a ransomware incident by implementing necessary defences and policies based on the assessment.
Essential Components for a Successful Ransomware Tabletop Exercise
Three key components to guarantee a successful ransomware tabletop exercise should be considered: pre-exercise preparation, in-exercise collaboration, and post-exercise debrief. An information security expert, preferably an external consultant and facilitator, is the most suitable choice to facilitate the exercise, as they have extensive knowledge of cyber threats and can guide the participants effectively.
The facilitator should prompt participants to react to the attack scenario as though it were a real-life occurrence, interjecting pertinent points, providing examples of the steps that should be taken during each response phase, and asking relevant questions to guide the conversations towards the essential aspects of ransomware readiness. Ransomware tabletop exercises are crucial for improving an organisation’s preparedness for cyber threats.

Before the exercise begins, it’s essential to confirm that all participants know their roles and thoroughly understand the incident response plan. Participants in a ransomware tabletop exercise typically assume roles such as:
Representatives from security, IT, legal, human resources, and public relations
Information security experts
The incident response plan is an organisation’s framework or playbook to respond to a security incident. It contains the steps and procedures that participants should follow should an incident occur, including forming an incident response team, defining responsibilities, and establishing policies. Ensuring participants are familiar with the incident response plan is crucial in guaranteeing a seamless and efficient exercise.
During the ransomware tabletop exercise, it’s essential to cultivate a collaborative environment that encourages constructive and professional conversation among participants. Providing the exercise scenario to all participants simultaneously ensures everyone has the same information and can collaborate efficiently. An independent facilitator plays a crucial role in setting the appropriate guidelines and atmosphere for the exercise.
Developing an atmosphere of accountability and learning, where everyone is comfortable contributing their thoughts and differing opinions are welcomed, is of utmost importance. A stress-free, open, and professional environment enables participants to work together effectively in responding to the ransomware attack scenario and identifying areas for improvement.
Realistic Scenarios and Scenario Variations
Any successful tabletop exercise includes realistic situations. For instance, a believable situation could entail a ransomware attack originating from a phishing email, leading to the encryption of confidential client data. The situation should evolve, covering the breach’s discovery, reporting to law enforcement, a ransom demand, system restoration from backups, and the decision-making process regarding the ransom’s feasibility.
Before the exercise, the leaders should devise several credible ‘curveballs’ to introduce during the exercise. For example, the ransom demand could be exorbitantly high in one situation. In a different situation, a secondary ransomware attack, deploying another variant, could occur within a day. These diversifications allow teams to adapt to unforeseen conditions and evaluate various incident response plan elements.
The post-exercise debrief entails reflecting on the exercise, preparing an after-action report, and integrating the findings into upcoming plans. If an external party or facilitator is utilised for the exercise, they will be responsible for taking detailed notes and providing a report afterwards.
Post-exercise analysis, also known as post-tabletop analysis, is essential to analyse the outcomes of the tabletop exercise, compile an after-action report or summary memo, and potentially survey or obtain participants’ feedback. An after-action report intends to evaluate the exercise and generate a report summarising insights and critical analysis of participants’ responses and conversations, helping organisations identify areas for improvement.

Integrating Ransomware Preparedness into the Exercise
When incorporating ransomware preparedness into the exercise, it’s essential to consider factors like compliance with relevant regulations and promoting proactive defence measures. Addressing compliance is critical for effective ransomware preparedness during a workout, ensuring that the organisation adheres to regulatory requirements and guidelines related to cybersecurity and data protection.
Proactive defence measures can be integrated into ransomware preparedness exercises by implementing critical controls identified in the ransomware preparedness assessment, such as regular and secure backups, updating and patching systems, and implementing advanced threat protection tools. These measures help strengthen defences against ransomware attacks and improve the organisation’s cyber resilience.
Encouraging Proactive Defense Measures
Implementing critical controls from a ransomware preparedness assessment is an effective way to bolster defences against ransomware attacks. Some of these vital controls include:
Ransomware incident response plan
Third-party vendor management
Backup and audit logging
Vulnerability and patch management
Access and privilege controls
Email and web filtering
Network and endpoint monitoring
User activity logging and audit configurations
By integrating these critical controls into ransomware preparedness exercises, organisations can proactively defend against attacks and improve their overall security posture. These proactive defence measures help organisations stay one step ahead of cybercriminals and protect valuable data and assets.
