DynamoDB tables should use KMS encryption

Description

DynamoDB tables should have encryption at rest enabled. All DynamoDB tables are encrypted by default using an AWS owned key. AWS managed KMS keys and customer managed KMS keys are also supported. This rule verifies that encryption at rest is not explicitly disabled.

Remediation

Ensure encryption at rest is enabled on the table. AWS owned keys (the default), AWS managed KMS keys, and customer managed KMS keys are all acceptable. For guidance, see DynamoDB encryption at rest.
