What is an Information Systems Audit?

An Information Systems (IS) audit is a comprehensive examination and evaluation of an organization's information technology infrastructure, systems, and operations. It aims to assess the effectiveness of IT controls, security measures, compliance with regulations, and alignment with business objectives. IS audits help identify vulnerabilities, ensure data integrity, and provide recommendations for improvement to safeguard critical information assets.
