Nepture logs export should be enabled

Explanation

Neptune does not have auditing by default. To ensure that you are able to accurately audit the usage of your Neptune instance you should enable export logs.

Possible Impact

Limited visibility of audit trail for changes to Neptune

Suggested Resolution

Enable export logs

Insecure Example

The following example will fail the aws-neptune-enable-log-export check.

resource "aws_neptune_cluster" "bad_example" {
  cluster_identifier                  = "neptune-cluster-demo"
  engine                              = "neptune"
  backup_retention_period             = 5
  preferred_backup_window             = "07:00-09:00"
  skip_final_snapshot                 = true
  iam_database_authentication_enabled = true
  apply_immediately                   = true
  enable_cloudwatch_logs_exports      = []
}

Secure Example

The following example will pass the aws-neptune-enable-log-export check.

resource "aws_neptune_cluster" "good_example" {
  cluster_identifier                  = "neptune-cluster-demo"
  engine                              = "neptune"
  backup_retention_period             = 5
  preferred_backup_window             = "07:00-09:00"
  skip_final_snapshot                 = true
  iam_database_authentication_enabled = true
  apply_immediately                   = true
  enable_cloudwatch_logs_exports      = ["audit"]
}
