Database Security

Summary

Encryption at rest and in transit, network isolation (placing databases in private subnets), and least-privilege access controls — databases hold the most sensitive data in most systems and deserve the strictest security posture.

• 1Verify encryption is enabled on a sample managed database.
• 2Place a database in a private subnet, accessible only from application servers, not the public internet.
• 3Learn to use IAM database authentication instead of long-lived static passwords where available.
