正解: A
Risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. Risk appetite reflects the organization's risk culture, strategy, and tolerance, and guides the organization's risk management practices. The most useful information about risk appetite can be obtained from the risk policies, which are the documents that define the organization's risk management framework, principles, objectives, roles, responsibilities, and processes. Risk policies also establish the criteria and thresholds for identifying, assessing, prioritizing, mitigating, and monitoring risks, as well as the reporting and escalation mechanisms for risk issues. By reviewing the risk policies, an IS auditor can evaluate whether they are consistent, comprehensive, and aligned with the organization's risk appetite and whether they provide clear guidance and direction for managing risks effectively.
The other options are not correct because they are either not the most useful or not relevant to risk appetite.
Risk assessments are the processes of identifying, analyzing, and evaluating the risks that may affect the organization's objectives. Risk assessments provide information about the current risk profile and exposure of the organization, but they do not indicate the organization's risk appetite or preferences. Prior audit reports are the documents that summarize the findings, recommendations, and conclusions of previous audits. Prior audit reports may provide information about the past performance and issues of the organization's risk management practices, but they do not reflect the organization's risk appetite or expectations. Management assertion is a statement or declaration made by management about the accuracy, completeness, validity, or reliability of a certain fact or data. Management assertion may provide information about the management's confidence or opinion on a specific risk or issue, but it does not represent the organization's risk appetite or criteria.
