Audit planning is the process of developing an overall strategy and approach for conducting an audit. Audit planning involves identifying the objectives, scope, criteria, and methodology of the audit, as well as the resources, schedule, and reporting requirements. Audit planning also involves performing a risk assessment to identify and prioritize the areas of highest risk and significance for the audit1.
Risk assessment is a systematic process of evaluating the potential risks that may be involved in a projected activity or undertaking. Risk assessment involves identifying the sources and causes of risk, analyzing the likelihood and impact of risk, and determining the level of risk and the appropriate response2.
During audit planning, the IS audit manager is considering whether to budget for audits of entities regarded by the business as having low risk. The best course of action in this situation is C. Validate the low-risk entity ratings and apply professional judgment.
This is because validating the low-risk entity ratings can help to ensure that the risk assessment is accurate, reliable, and consistent with the business objectives and expectations. Validating the low-risk entity ratings can also help to identify any changes or developments that may affect the risk profile of the entities since the last assessment. Applying professional judgment can help to determine whether the low-risk entities should be included or excluded from the audit plan, based on factors such as materiality, relevance, significance, and assurance needs3.
