Best Way to Ensure Effectiveness of Cybersecurity Incident Response Process

C.

Among the options listed, periodic tabletop exercises involving key stakeholders is the BEST way for management to ensure the effectiveness of the cybersecurity incident response process.

Periodic tabletop exercises are simulations of cybersecurity incidents that involve key stakeholders in the incident response process, including IT staff, incident responders, business units, and management. These exercises allow management to test and evaluate the effectiveness of the incident response process in a controlled environment, identify areas for improvement, and refine the incident response plan based on the results.

Through tabletop exercises, management can also test the effectiveness of their communication and collaboration with key stakeholders during a cybersecurity incident. This can help to ensure that everyone involved in the incident response process understands their roles and responsibilities and knows how to respond appropriately in the event of a real incident.

While periodic update of incident response process documentation, periodic reporting of cybersecurity incidents to key stakeholders, and periodic cybersecurity training for staff involved in incident response are important components of an effective incident response process, they are not as comprehensive as tabletop exercises.

For example, updating documentation alone does not necessarily ensure that the incident response process will be effective in practice. Similarly, reporting incidents and providing training can help to improve incident response, but they do not provide the same level of hands-on experience and evaluation as tabletop exercises.

Therefore, periodic tabletop exercises involving key stakeholders are the best way for management to ensure the effectiveness of the cybersecurity incident response process.
