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.

The most effective method of destroying sensitive data stored on electronic media is physical destruction, which involves breaking, shredding, melting, or incinerating the media to make it unreadable and unrecoverable. Degaussing, random character overwrite, and low-level formatting are methods of sanitizing or erasing data from electronic media, but they do not guarantee complete destruction of data and may leave some traces that can be recovered by advanced techniques. Therefore, physical destruction is the most secure and reliable method of data disposal for sensitive data.

Quarterly steering committee meetings best demonstrate alignment of the IT department with the corporate mission because they provide a regular forum for strategic planning, decision making, and communication between IT leaders and business stakeholders12. Steering committee meetings help to ensure that IT goals and initiatives are aligned with the business vision, mission, and objectives, and that IT performance and value are monitored and evaluated34.
