Isaca CISM Exam With Confidence Using Practice Dumps

Performing an analysis of the change is the first step in addressing the issue of an IT employee making a change to a firewall rule outside of the change control process because it helps to understand the reason, impact, and risk of the change and to decide whether to approve, reject, or reverse it. Requiring that the change be reversed is not the first step because it may cause more disruption or damage without proper analysis and testing. Reviewing the change management process is not the first step because it does not address the specific issue or incident at hand, but rather focuses on improving the process for future changes. Reporting the event to senior management is not the first step because it does not resolve the issue or incident, but rather escalates it without sufficient information or recommendation.

Cost-benefit analysis (CBA) is a method of comparing the costs and benefits of different alternatives for achieving a desired outcome. CBA can help information security managers to choose the best controls to mitigate risk to acceptable levels by providing a rational and objective basis for decision making. CBA can also help information security managers to justify their choices to senior management, stakeholders, and auditors by demonstrating the value and return on investment of the selected controls. CBA can also help information security managers to prioritize and allocate resources for implementing and maintaining the controls12.

CBA involves the following steps12:

Identify the objectives and scope of the analysis

Identify the alternatives and options for achieving the objectives

Identify and quantify the costs and benefits of each alternative

Compare the costs and benefits of each alternative using a common metric or criteria

Select the alternative that maximizes the net benefit or minimizes the net cost

Perform a sensitivity analysis to test the robustness and validity of the results

Document and communicate the results and recommendations

CBA is mainly driven by the information security manager’s decision, but it can also take into account other factors such as best practices, control frameworks, and regulatory requirements. However, these factors are not the primary drivers of CBA, as they may not always reflect the specific needs and context of the organization. Best practices are general guidelines or recommendations that may not suit every situation or environment. Control frameworks are standardized models or methodologies that may not cover all aspects or dimensions of information security. Regulatory requirements are mandatory rules or obligations that may not address all risks or threats faced by the organization. Therefore, CBA is the best method to choose the most appropriate and effective controls to mitigate risk to acceptable levels, as it considers the costs and benefits of each control in relation to the organization’s objectives, resources, and environment12. References = CISM Domain 2: Information Risk Management (IRM) [2022 update], Five Key Considerations When Developing Information Security Risk Treatment Plans

 The needs of the organization define the triggers within a business continuity plan (BCP). Triggers are the events or conditions that initiate the activation of the BCP. The triggers should be based on the organization’s business objectives, risk appetite, recovery time objectives, and recovery point objectives. The triggers should also be aligned with the organization’s information security policy, disaster recovery plan, and gap analysis. However, these are not the primary factors that define the triggers, but rather the supporting elements that help implement the BCP. The needs of the organization are the main drivers for determining the triggers, as they reflect the organization’s priorities, expectations, and requirements for business continuity. References =
