What is a cyber tabletop exercise? A cyber tabletop exercise is a team-based simulation conducted in a discussion format that enables an organization to assess how well it can handle cybersecurity incidents. Unlike technical testing, a cyber tabletop exercise examines team communication and decision-making processes as they execute incident response procedures in response to simulated cyber attacks.
 
As cyber risks continue to grow, various sectors employ a cyber tabletop exercise to identify gaps in readiness, enhance team coordination, and boost cybersecurity resilience. The main aim of cyber tabletop exercise is to test the organization's incident response plan, in which members are given a realistic cyber incident scenario, like ransomware phishing insider attack, data breach, among others. At each stage of the incident, such as detection escalation containment, recovery, and post-incident review, team members will role-play the response; these discussion will help discover if the existing policy, communication method, and decision-making process are feasible and clear.
 
The best tabletop exercises are multi-departmental representations, not just IT representatives. The best exercises include security, executive team and legal reps HR communications, compliance and BUMs; representing the whole spectrum of incident management. Such scenarios always illustrate to the participants how important communication and knowing who is responsible for what are during a cyber event.
 
A good benefit of a cyber tabletop exercise is not so much the planning that is done, but any weaknesses that might be found that would not be identified until a major incident happened. During the exercise the identified flaws may be contact details, reporting structure, missing documentation or lack of understanding over responsibility before the event actually takes place.
 
Various situations may be selected based on each organisation's goals and industry-specific risk. Typical use cases in Industry may include ransomware attacks, business email compromise, cloud service failures, supply chain compromises, DDoS attack, unintentional data disclosure, etc. It is useful if organisation simulate a range of situations to gain wider experience on different attack nature.
 
Repeating a cyber tabletop exercise will enable continuous improvement. As cybersecurity threats, tools, and regulations evolve with an organisation's business activities, response planning needs to be revisited from time to time. Improving policies will be based on what has been learned in exercise sessions and will be reinforced through staff re-training and more up-to-date communication protocols.
 
In addition, documentation is important for a cyber tabletop exercise. Observations, responses by participating individuals, risks that were encountered, as well as suggested improvements for future exercises should be reported in a summary report. This documentation can act as documentation for future exercises and governance towards improvement of cybersecurity.
 
To sum up, a cyber tabletop exercise is an essential activity to assess incident response planning and organizational preparedness. Conducting such exercises can help organizations test cybersecurity scenarios, facilitate cross-department collaboration, detect weaknesses in policies and procedure, and drive a continuous improvement culture.
