The most important consideration when developing tabletop exercises within a cybersecurity incident response plan is to identify the scope and scenarios that are relevant to current threats faced by the organization, as this will ensure that the exercises are realistic, meaningful, and effective in testing and improving the incident response capabilities12. The scope and scenarios should reflect the organization's risk profile, business objectives, and operational environment, and should cover a variety of potential incidents that could impact the organization's assets, operations, and reputation34.
