The first step in conducting a fraud risk assessment is to identify relevant fraud risk factors (Option A). This involves understanding the internal and external factors that could influence the likelihood and impact of fraud within the organization. Identifying these risk factors sets the foundation for subsequent steps, such as identifying potential fraud schemes, existing controls, and red flags. This approach aligns with the guidance provided in the IIA's Practice Guide on Managing the Business Risk of Fraud, which outlines the process of conducting comprehensive fraud risk assessments starting with identifying risk factors.

COSO Framework for Fraud Risk Management

The oversight of an organization's risk management framework is primarily the responsibility of the board of directors. The board's role includes ensuring that risk management processes are integrated with overall organizational processes and that the strategies and policies regarding risk management are effectively managed and aligned with the organization's objectives. Operational management, internal auditors, and the head of risk management each play roles within the framework established by the board but do not have overall oversight responsibility.
Institute of Internal Auditors (IIA) - International Professional Practices Framework (IPPF)

Board endorsement of the internal audit plan strengthens organizational independence by ensuring that internal audit activities align with governance priorities rather than management's interests, in line with IIA standards.

The primary responsibility for the internal audit activity in helping management maintain effective controls is promoting continuous monitoring. Continuous monitoring involves regularly reviewing control processes and performance to ensure they are effective and making adjustments as necessary. This proactive approach enables the internal audit activity to assist management in maintaining a robust control environment that can adapt to changes in the organization or its external environment.
