Amazon has announced security enhancements for Redshift to prevent data breaches due to misconfigurations. The updates include restricting public access by default, enabling encryption for all clusters, and enforcing SSL/TLS connections to prevent unauthorized access and data interception. These changes apply to newly created and restored clusters but do not affect existing ones. AWS urges users to review their configurations to align with the new security defaults and avoid disruptions. Customers can refer to the Management Guide or contact AWS Support for assistance.
