Amazon Redshift enhances security by changing default behavior in 2025
Security Blog
Amazon Redshift is implementing three key security enhancements for new clusters in 2025:
- Disabling public accessibility by default, restricting cluster access to within the VPC
- Mandating encryption for all new clusters, using AWS-owned KMS keys if no specific key is provided
- Enforcing secure SSL connections by default through a new parameter group
These changes aim to improve default security postures by:
- Reducing unauthorized access risks
- Protecting sensitive data through encryption
- Preventing potential eavesdropping and man-in-the-middle attacks
Customers are advised to review their current configurations and update workflows to align with these new security defaults.
