An IT audit is the process of collecting and evaluating records of an organization’s information

information systems are safeguarding assets, maintaining data integrity, and operating effectively
and efficiently enough to achieve the organization’s goals or objectives. These reviews may be
performed in conjunction with a financial statement audit, internal audit, or other form of
attestation engagement. Audit records are also used to troubleshoot system issues.
