The explanation given in the manual is:

Incident classification criteria enable an organization to prioritize incidents based on their impact and urgency. This allows for an optimized allocation of recovery resources to minimize business disruption and ensure timely restoration of normal operations. The other choices are benefits of incident management but not directly related to incident classification criteria.

Chain of custody is the MOST important requirement when collecting admissible evidence, because it ensures the integrity and authenticity of the evidence by documenting its history, handling, and storage. Chain of custody records who, what, when, where, why, and how the evidence was collected, analyzed, and preserved. Without a proper chain of custody, the evidence may be challenged or rejected in a court of law. Need to know, preserving audit logs, and due diligence are important aspects of evidence collection, but they are not as critical as chain of custody. References = CISM Review Manual, 16th Edition, page 3031; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 1492The most important requirement when collecting admissible evidence is the chain of custody. The chain of custody is a documented record of who had control of the evidence at any given time, from the point of collection until the evidence is presented in court. This is important in order to ensure the evidence can be authenticated and is not subject to tampering or any other form of interference. Other important considerations include need to know, preserving audit logs, and due diligence.

 Information asset classification is the process of identifying, labeling, and categorizing information assets based on their value, sensitivity, and criticality to the organization. Information asset classification helps to establish appropriate security controls, policies, and procedures for protecting the information assets from unauthorized access, use, disclosure, modification, or destruction. One of the key elements of information asset classification is assigning owners to each information asset. Owners are responsible for managing the information asset throughout its lifecycle, including defining its security requirements, implementing security controls, monitoring its usage and performance, reporting any incidents or breaches, and ensuring compliance with legal and regulatory obligations. Therefore, assigning responsibility to the database administrator (DBA) is the best way to address the situation where several production databases do not have owners assigned to them. References = CISM Review Manual 15th Edition1, page 256; Information Asset and Security Classification Procedure2.

The most effective way to gain senior management approval of security investments in network infrastructure is by demonstrating that targeted security controls tie to business objectives.

Security investments should be tied to business objectives and should support the overall goals of the organization. By demonstrating that the security controls will directly support the organization's business objectives, senior management will be more likely to approve the investment.

According to the Certified Information Security Manager (CISM) Study Manual, "To gain senior management's approval for investments in security, it is essential to show how the security controls tie to business objectives and are in support of the overall goals of the organization."

While performing penetration tests against the network, highlighting competitor performance, and presenting comparable security implementation estimates from vendors are all useful in presenting the value of security investments, they are not as effective as demonstrating how the security controls will support the organization's business objectives.
