If an internal auditor identifies that some employees have inappropriate access to a key system in the early stage of an audit, the best course of action is to issue an interim audit report so that management can implement action plans. This approach ensures that the identified issue is formally communicated to management promptly, allowing them to take immediate corrective action to mitigate the risk. It also documents the auditor's findings and recommendations, providing a clear audit trail and supporting accountability. Obtaining verbal assurance or creating a ticket might address the issue temporarily but lacks the formal documentation and follow-up mechanisms inherent in an interim audit report.
