AWS::Config::OrganizationConfigRule

Adds or updates an Amazon Config rule for your entire organization to evaluate if your Amazon resources comply with your desired configurations. For information on how many organization Amazon Config rules you can have per account, see Service Limits in the Amazon Config Developer Guide.

Only a management account and a delegated administrator can create or update an organization Amazon Config rule. When calling the OrganizationConfigRule resource with a delegated administrator, you must ensure Amazon Organizations ListDelegatedAdministrator permissions are added. An organization can have up to 3 delegated administrators.

The OrganizationConfigRule resource enables organization service access through the EnableAWSServiceAccess action and creates a service-linked role AWSServiceRoleForConfigMultiAccountSetup in the management or delegated administrator account of your organization. The service-linked role is created only when the role does not exist in the caller account. Amazon Config verifies the existence of role with GetRole action.

To use the OrganizationConfigRule resource with delegated administrator, register a delegated administrator by calling Amazon Organization register-delegated-administrator for config-multiaccountsetup.amazonaws.com.

There are two types of rules: Amazon Config Managed Rules and Amazon Config Custom Rules. You can use PutOrganizationConfigRule to create both Amazon Config Managed Rules and Amazon Config Custom Rules.

Amazon Config Managed Rules are predefined, customizable rules created by Amazon Config. For a list of managed rules, see List of Amazon Config Managed Rules. If you are adding an Amazon Config managed rule, you must specify the rule's identifier for the RuleIdentifier key.

Amazon Config Custom Rules are rules that you create from scratch. There are two ways to create Amazon Config custom rules: with Lambda functions (Amazon Lambda Developer Guide) and with Guard (Guard GitHub Repository), a policy-as-code language. Amazon Config custom rules created with Amazon Lambda are called Amazon Config Custom Lambda Rules and Amazon Config custom rules created with Guard are called Amazon Config Custom Policy Rules.

If you are adding a new Amazon Config Custom Lambda rule, you first need to create an Amazon Lambda function in the management account or a delegated administrator that the rule invokes to evaluate your resources. You also need to create an IAM role in the managed account that can be assumed by the Lambda function. When you use PutOrganizationConfigRule to add a Custom Lambda rule to Amazon Config, you must specify the Amazon Resource Name (ARN) that Amazon Lambda assigns to the function.

Examples

Managed Rule

The following example creates a managed organization config rule.

{
    "BasicOrganizationConfigRule": {
        "Type": "AWS::Config::OrganizationConfigRule",
        "Properties": {
            "OrganizationConfigRuleName": "OrganizationConfigRuleName",
            "OrganizationManagedRuleMetadata": {
                "RuleIdentifier": "CLOUD_TRAIL_ENABLED",
                "Description": "Cloudtrail enabled rule"
            },
            "ExcludedAccounts": [
                "accountId"
            ]
        }
    }
}

BasicOrganizationConfigRule:
    Type: "AWS::Config::OrganizationConfigRule"
    Properties:
        OrganizationConfigRuleName: "OrganizationConfigRuleName"
        OrganizationManagedRuleMetadata:
            RuleIdentifier: "CLOUD_TRAIL_ENABLED"
            Description: "Cloudtrail enabled rule"
        ExcludedAccounts:
        - "accountId"

Custom Rule

The following example creates a custom organization config rule.

{
    "BasicOrganizationConfigRule": {
        "Type": "AWS::Config::OrganizationConfigRule",
        "Properties": {
            "OrganizationConfigRuleName": "OrganizationConfigRuleName",

                "OrganizationConfigRuleTriggerTypes": [
                    "ScheduledNotification"
                ]
            },
            "ExcludedAccounts": [
                "accountId"
            ]
        }
    }
}

BasicOrganizationConfigRule:
    Type: "AWS::Config::OrganizationConfigRule"
    Properties:
        OrganizationConfigRuleName: "OrganizationConfigRuleName"
        OrganizationCustomRuleMetadata:
            LambdaFunctionArn: "CustomRuleLambdaArn"
            OrganizationConfigRuleTriggerTypes:
                - "ScheduledNotification"
            ExcludedAccounts:
