AWS securityhub medium security documentation change
Summary
Added new control [RDS.45] requiring audit logging for Aurora MySQL DB clusters
Security assessment
The change introduces a security control requiring audit logging to capture database activity for security/compliance audits. It explicitly references NIST security standards and addresses detection of unauthorized access/modifications through logging.
