What type of control should an IS auditor recommend to address issues of corrupt data in a database?

The most appropriate recommendation for addressing issues of corrupt data in a database involves the use of restore procedures. When data corruption occurs, it typically signifies an underlying problem that could stem from hardware failures, software bugs, or user errors. By implementing restore procedures, an organization can revert the database back to a known good state, effectively eliminating the corrupted data and restoring operational integrity.

Restoring from a backup allows the organization to recover lost or corrupted data while maintaining data integrity and availability. Additionally, this process is crucial in maintaining trust in the database system, ensuring that reliable and accurate data is available for users.

While defining standards and monitoring for compliance, ensuring only authorized personnel can update the database, and establishing controls for concurrent access issues are all important aspects of database security and management, they do not directly address the immediate problem of data corruption. These actions are preventive measures aimed at reducing the risk of data corruption, whereas restoring procedures are a reactive approach necessary for correcting the consequences of corruption that has already occurred.
