Description

CloudWatch log groups are encrypted by default. However, utilizing customer managed KMS keys gives you more control over key rotation and provides auditing visibility into key usage.

How to fix?

Configure the aws_cloudwatch_log_group kms_key_id field with a KMS key ARN specified for encrypting log data.

Example Configuration

resource "aws_cloudwatch_log_group" "example" {
  kms_key_id = "${aws_kms_key.example.arn}"
  # other required fields here
}
