Understanding Internal Audit
The internal audit function operates independently from management to provide unbiased evaluations of processes, systems, and controls. Its scope may include financial reporting, operational efficiency, compliance with laws and policies, and information security.
Internal auditors use a risk-based approach, focusing resources on areas with the greatest potential impact. Findings are reported to senior management and the board or audit committee, along with practical recommendations.
Unlike external audits, which focus primarily on financial statements, internal audits are continuous and broader in scope, emphasizing improvement and prevention.
