Section: INCIDENT MANAGEMENT AND RESPONSE

The criticality to business should always drive the decision. Regulatory requirements could be more flexible than business needs. The financial value of an asset could not correspond to its business value. While a consideration, IT resource availability is not a primary factor.

Section: INFORMATION SECURITY PROGRAM MANAGEMENT
Explanation:
Developing procedures and guidelines to ensure that business processes address information security risk is critical to the management of an information security program. Developing procedures and guidelines establishes a baseline for security program performance and consistency of security activities.

Explanation
= Testing response scenarios is the most important factor in increasing the effectiveness of incident responders, as it allows them to practice their skills, identify gaps and weaknesses, evaluate the adequacy and feasibility of the incident response plan, and improve their coordination and communication. Testing response scenarios can also help to enhance the confidence and readiness of the incident responders, as well as to measure their performance and compliance with the policies and procedures. Testing response scenarios can be done through various methods, such as tabletop exercises, simulations, drills, or full-scale exercises, depending on the scope, objectives, and complexity of the scenarios.
The other options are not as important as testing response scenarios, although they may also contribute to the effectiveness of incident responders. Communicating with the management team is important to ensure that the incident responders have the necessary support, resources, and authority to carry out their tasks, as well as to report the status and outcomes of the incident response. However, communication alone is not sufficient to increase the effectiveness of incident responders, as they also need to have the relevant knowledge, skills, and experience to handle the incidents. Integrating staff with the IT department may help to facilitate the collaboration and information sharing between the incident responders and the IT staff, who may have the technical expertise and access to the systems and data involved in the incidents. However, integration alone is not enough to increase the effectiveness of incident responders, as they also need to have the appropriate roles, responsibilities, and processes to manage the incidents. Reviewing the incident response plan annually is important to ensure that the plan is updated and aligned with the current risks, threats, and business requirements, as well as to incorporate the lessons learned and best practices from previous incidents.
However, reviewing the plan alone is not enough to increase the effectiveness of incident responders, as they also need to test and validate the plan in realistic scenarios and conditions. References = CISM Review Manual, 16th Edition, ISACA, 2022, pp. 223-225, 230-231.

A warm site is not fully equipped with the company's main systems; therefore, the tapes should be tested using the company's production systems. Inspecting the facility and checking the tape inventory does not guarantee that the tapes are usable.
