aggregate-all-regions

Default Severity: high

Explanation

The configuration aggregator should be configured with all_regions for the source.

This will help limit the risk of any unmonitored configuration in regions that are thought to be unused.

Possible Impact

Sources that aren't covered by the aggregator are not include in the configuration

Suggested Resolution

Set the aggregator to cover all regions

Insecure Example

The following example will fail the aws-config-aggregate-all-regions check. 

 resource "aws_config_configuration_aggregator" "bad_example" {
    name = "example"

    account_aggregation_source {
      account_ids = ["123456789012"]
      regions     = ["us-west-2", "eu-west-1"]
    }
 }

Secure Example

The following example will pass the aws-config-aggregate-all-regions check. 

 resource "aws_config_configuration_aggregator" "good_example" {
    name = "example"

    account_aggregation_source {
      account_ids = ["123456789012"]
      all_regions = true
    }
 }
