• Enforces SSL for all database connections
• Allows granular access control through multiple policy layers
• Best practices include:
• Implementing least-privilege access
• Using short-lived authentication tokens
• Configuring strict security groups
• Leveraging VPC and network-level controls

The article emphasizes a multi-layered security approach to protect Aurora DSQL clusters from unauthorized access while maintaining flexibility for legitimate users.
