Description​

This policy identifies AWS RDS Multi-AZ Clusters where the Auto Minor Version Upgrade feature is disabled.

Rationale​

Enabling automatic minor version upgrades ensures that clusters receive the latest engine updates, which may include critical security patches, bug fixes, and performance improvements. For Multi-AZ clusters designed to provide high availability, maintaining consistent updates across all instances is essential for stability, security, and uniform behavior, particularly during failover events.

Audit​

This policy flags a Multi-AZ AWS RDS Cluster as INCOMPLIANT if the Auto Minor Version Upgrade field is set to No.

A Cluster is marked as INAPPLICABLE if the Multi-AZ field is set to false.
