Internal audit is an independent, objective assurance and consulting activity designed to add value and improve an organization’s operations. It helps organizations accomplish objectives by evaluating and improving the effectiveness of risk management, control, and governance processes.

Key Principles:

Independence: Internal auditors should report functionally to the board or audit committee.
Objectivity: Auditors must remain unbiased in assessing controls and processes.
Systematic Approach: Audits should follow structured methodologies and standards (e.g., IIA Standards).
Scope: Broadly covers financial, operational, compliance, IT, and strategic risk areas.
