The purpose of an information systems audit is to evaluate the effectiveness, security, and efficiency of an organization’s information systems and controls. This process involves a thorough examination of IT infrastructure, policies, and processes to ensure compliance with regulations and best practices. Auditors assess risk management, data integrity, and security measures, identifying vulnerabilities and providing recommendations for improvements. A well-conducted audit not only enhances trust in the organization's data management but also supports strategic decision-making and operational effectiveness, ultimately safeguarding organizational assets and ensuring ongoing compliance.
