Redshift Serverless namespaces should use KMS encryption

Description

Redshift Serverless namespaces should have encryption at rest enabled to protect stored data and snapshots. AWS owned keys (the default), AWS managed KMS keys, and customer managed KMS keys are all acceptable. This rule verifies that encryption at rest is not explicitly disabled.

Remediation

Ensure encryption at rest is configured for the namespace. AWS owned keys, AWS managed KMS keys, and customer managed KMS keys are all acceptable. For guidance, see Data protection in Amazon Redshift Serverless.
