The best risk response for an identified high probability risk scenario involving a critical, proprietary business function with an annualized cost of control higher than the annual loss expectancy is to accept the risk.
Accepting the risk means acknowledging the risk but choosing not to take any specific action to address it.
This strategy is suitable when the cost of implementing controls exceeds the potential loss, as in this scenario.
The organization recognizes the risk, but the cost-benefit analysis suggests that the potential loss is acceptable given the higher cost of control. The other options are not the best risk responses, as they may not be feasible, practical, or cost-effective in this scenario. Mitigating the risk means reducing the risk by implementing controls or measures to minimize its potential impact, but this would increase the cost of control, which is already higher than the annual loss expectancy. Transferring the risk means shifting the risk to another party, typically through insurance or contracts, but this may not be possible or advisable for a critical, proprietary business function, and it may also increase the overall cost burden. Avoiding the risk means eliminating the risk entirely by not engaging in the activity that poses the risk, but this may disrupt essential business operations and potentially result in other adverse consequences.

Internal audit provides independent assurance to the board and senior management regarding the effectiveness of risk management program implementation, consistent withGovernance and Assurance Principles.

A risk heat map is a graphical tool that displays the results of a risk analysis in a matrix format, using colors and symbols to indicate the level and priority of the risks. A risk heat map can show the distribution and comparison of the risks based on various criteria, such as likelihood, impact, category, source, etc.
A risk heat map is most commonly used as part of an IT risk analysis to facilitate risk assessment, which is the process of determining the significance and urgency of the risks that may affect the organization's objectives and operations. Risk assessment involves measuring and comparing the likelihood and impact of various risk scenarios, and prioritizing them based on their magnitude and importance.
A risk heat map can help to facilitate risk assessment by providing a visual and intuitive representation of the risk profile, and highlighting the most critical and relevant risks that need to be addressed or monitored. A risk heat map can also help to communicate and report the riskanalysis results to different stakeholders, and to support the decision making and planning for the risk response and treatment.
The other options are not the most common uses of a risk heat map as part of an IT risk analysis, because they do not address the main purpose and benefit of a risk heat map, which is to facilitate risk assessment.
Risk identification is the process of finding and describing the risks that may affect the organization's objectives and operations. Risk identification involves defining the risk sources, events, causes, and impacts, and documenting them in a risk register. A risk heat map is not commonly used to facilitate risk identification, because it does not provide the detailed and comprehensive information that is needed to identify and describe the risks, and it may not cover all the relevant or potential risks that may exist or emerge.
Risk treatment is the process of selecting and implementing the appropriate actions or plans to address the risks that have been identified, analyzed, and evaluated. Risk treatment involves choosing one of the following types of risk responses: mitigate, transfer, avoid, or accept. A risk heat map is not commonly used to facilitate risk treatment, because it does not provide the specific and feasible information that is needed to select and implement the risk responses, and it may not reflect the cost-benefit or feasibility analysis of the risk responses.
Risk communication is the process of exchanging and sharing the information and knowledge about the risks and their responses among the relevant stakeholders. Risk communication involves informing, consulting, and involving the stakeholders in the risk management process, and ensuring that they understand and agree on the risk objectives, criteria, and outcomes. A risk heat map is not commonly used to facilitate risk communication, because it does not provide the complete and accurate information that is needed to communicate and share the risks and their responses, and it may not address the different needs, expectations, and perspectives of the stakeholders.

The best way to ensure key risk indicators (KRIs) provide value to risk owners is to provide timely notification of the changes in the risk exposure. KRIs are metrics that provide an early warning of increasing risk exposure in various areas of the organization. By providing timely notification of the KRI values, the risk owners can be alerted of the risk situation and take appropriate actions to manage the risk. Ongoing training, return on investment (ROI), and cost minimization are other possible ways to ensure KRIs provide value, but they are not as effective as timely notification.

Payroll system risk mitigation plans are the actions that are taken to reduce or eliminate the risk associated with payroll processing. When a migration from an in-house developed system to an external cloud-based solution is affecting a previously rated key risk scenario related to payroll processing, the first part of the risk register that should be updated is the payroll system risk mitigation plans. This is because the migration may introduce new risks or change the existing risks, and the risk mitigation plans may need to be revised or replaced accordingly. Updating the payroll system risk mitigation plans can help ensure that the risk level is acceptable and the payroll process is secure and reliable. According to the CRISC Review Manual 2022, one of the key risk treatment techniques is to update the risk action plan, which is a document that outlines the risk mitigation plans1. According to the CRISC Review Questions, Answers & Explanations Manual 2022, updating the risk mitigation plans is the correct answer to this question2.
Payroll system risk factors, payroll process owner, and payroll administrative controls are not the first part of the risk register that should be updated when a migration is affecting a key risk scenario. Payroll system risk factors are the sources or causes of risk, such as threats, vulnerabilities, or uncertainties. Payroll process owner is the person who is responsible for the payroll process and its outcomes. Payroll administrative controls are the policies, procedures, or guidelines that govern the payroll process. These parts of the risk register may also need to be updated, but they are not as urgent or critical as the risk mitigation plans.
Updating the risk factors, process owner, and administrative controls can help identify, assess, and monitor the risk, but they do not directly address the risk response. The risk response is the most important part of the risk management process, as it determines how the risk is handled and controlled.
