= Change management controls are the most effective in preventing the introduction of vulnerabilities that may disrupt the availability of a critical business application. Change management controls are the policies, procedures, and practices that govern the initiation, approval, implementation, testing, and documentation of changes to the information systems and infrastructure. Change management controls help to ensure that changes are authorized, planned, controlled, and monitored, and that they do not introduce any unintended or adverse effects on the security, functionality, performance, or reliability of the system or application. Change management controls also help to identify and mitigate any potential risks or issues that may arise from the changes, and to ensure that the changes are aligned with the business objectives and requirements. By implementing change management controls, the organization can prevent the introduction of vulnerabilities that may disrupt the availability of a critical business application, as well as enhance the quality and efficiency of the change process. References = CISM Review Manual 15th Edition, page 105, page 106.

 When an organization is aligning its incident response capability with a public cloud service provider, the information security manager’s first course of action should be to review the provider’s incident definitions and notification criteria. This is because the provider’s incident definitions and notification criteria may differ from the organization’s own, and may affect the scope, severity, and urgency of the incidents that need to be reported and handled. By reviewing the provider’s incident definitions and notification criteria, the information security manager can ensure that there is a common understanding and agreement on what constitutes an incident, how it is classified, and when and how it is communicated. This will help to avoid confusion, delays, or conflicts in the incident response process, and to establish clear roles and responsibilities between the organization and the provider. References = CISM Review Manual, 16th Edition, page 1021

Reviewing the provider’s incident definitions and notification criteria is the FIRST course of action when aligning the organization’s incident response capability with a public cloud service provider. This is because the organization needs to understand how the provider defines and classifies incidents, what their roles and responsibilities are, and how they will communicate with the organization in case of an incident. This will help the organization align its own incident response processes and expectations with the provider’s and ensure a coordinated and effective response.

The explanation given is: “A BIA is a process that identifies and evaluates the potential effects of natural and man-made events on business operations. It helps to understand how critical systems are interrelated and what their dependencies are. A BIA also helps to determine the RTOs for each system. The other options are not directly related to understanding the relationships between critical systems.”

= According to the CISM Review Manual (Digital Version), page 9, an information security steering committee is a group of senior managers from different business units and functions who provide guidance and oversight for the information security program. An information security steering committee is the best approach to make strategic information security decisions because it can:

Ensure alignment of information security strategy with business objectives and risk appetite1

Facilitate communication and collaboration among different stakeholders and promote information security awareness and culture2

Provide direction and support for information security initiatives and projects3

Monitor and review the performance and effectiveness of the information security program4

Resolve conflicts and issues related to information security policies and practices5

Establishing regular information security status reporting, business unit security working groups, and periodic senior management meetings are useful activities for information security management, but they are not sufficient to make strategic information security decisions without the involvement and guidance of an information security steering committee. References = 1: CISM Review Manual (Digital Version), page 9 2: 1 3: 2 4: 3 5: 4

An Information Security Steering Committee is a group of stakeholders responsible for providing governance and guidance to the organization on all matters related to information security. The committee provides oversight and guidance on security policies, strategies, and technology implementation. It also ensures that the organization is in compliance with relevant laws and regulations. Additionally, it serves as a forum for discussing security-related issues and ensures that security is taken into account when making strategic decisions.
