Ensure RDS instances have encryption at rest enabled

RDS instances should have storage encryption enabled using AWS KMS to protect data at rest.

Security Impact

Unencrypted database storage exposes data if underlying storage media is compromised.

How to Remediate

Enable encryption when creating new RDS instances. For existing instances, create an encrypted snapshot, restore to a new encrypted instance, and migrate.
