Objective
This lab is centered on deploying AWS Config within your AWS Organization for the first time. It's advisable to familiarize yourself with essential concepts of AWS Config, AWS CloudFormation, and how they integrate with AWS Organizations if you are new to them. In case you're interested I have published a concise summary of AWS Config in a separate post.
I was motivated to develop this lab since I was testing some AWS Organization features and started creating multiple accounts. Subsequently, I recognized that deploying basic AWS Security Services across all accounts would be the most secure approach.
Solution Structure
With that in mind, there are numerous options available for AWS Config. In this lab, we will utilize the following setup and components:
- (Pre-requisite) An AWS Organization must be already set up.
- We'll use AWS CloudFormation StackSets to automatically enable AWS Config on every member account. It should be noted that as per the AWS Documentation, the StackSet will not be deployed to the Management Account.
- As we plan to integrate AWS Config and AWS CloudFormation with AWS Organizations, we will assign the role of Delegated Administrator to one member account, thereby avoiding using the Management Account.
- We will create a single S3 Bucket within the Delegated Admin account to centralize AWS Config Log files from all member accounts.
- We will deploy a CloudFormation Stack to set up the Config StackSet and the centralized S3 Bucket.
- Once AWS Config is enabled across all accounts, we will begin establishing Organization Config Rules within the Delegated Admin account.
- Finally, a Config Aggregator will be set up in the Delegated Admin account to consolidate compliance data from all accounts and create reports.
Accounts Structure
Steps
Below are the sequential steps for deploying our AWS Config solution. The complete source code is available in the GitHub Repository.
- Assign a Delegated Administrator for AWS Config and CloudFormation.
- Establish AWS Config Recorders using CloudFormation StackSets.
- Implement Organization Config Rules across all accounts.
- Set up an AWS Aggregator for cross-account reporting.
Step 1. Assign a Delegated Administrator for AWS Config and CloudFormation.
As mentioned in AWS Documentation, run the following commands from the Management Account for enabling AWS Config and AWS CloudFormation for your Organization, and assigning a Delegated Admin.
- Enable service access as a delegated administrator for your organization to aggregate AWS Config data across your organization: ```
aws organizations enable-aws-service-access --service-principal=config.amazonaws.com
- Enable service access as a delegated administrator for your organization to deploy and manage AWS Config rules and conformance packs across your organization:
aws organizations enable-aws-service-access --service-principal=config-multiaccountsetup.amazonaws.com
- Enable service access as delegated administrator for your organization to create and manage stack sets across your organization:
aws organizations enable-aws-service-access --service-principal=member.org.stacksets.cloudformation.amazonaws.com
- To check if the enable service access is complete, enter the following command and press Enter to execute the command:
aws organizations list-aws-service-access-for-organization
You should see output similar to the following:
{
"EnabledServicePrincipals": [
{
"ServicePrincipal": "config-multiaccountsetup.amazonaws.com",
"DateEnabled": "2024-05-23T18:09:52.878000+00:00"
},
{
"ServicePrincipal": "config.amazonaws.com",
"DateEnabled": "2024-05-24T16:27:31.462000+00:00"
},
{
"ServicePrincipal": "member.org.stacksets.cloudformation.amazonaws.com",
"DateEnabled": "2024-05-24T16:56:08.933000+00:00"
}
]
}
- Next, enter the following commands to register a member account as a Delegated Admin for Config and CloudFormation:
aws organizations register-delegated-administrator --service-principal=config-multiaccountsetup.amazonaws.com --account-id MemberAccountID
aws organizations register-delegated-administrator --service-principal=config.amazonaws.com --account-id MemberAccountID
aws organizations register-delegated-administrator --service-principal=member.org.stacksets.cloudformation.amazonaws.com --account-id MemberAccountID
- To check if the registration of the delegated administrator is complete, enter the following commands:
aws organizations list-delegated-administrators --service-principal=config-multiaccountsetup.amazonaws.com
aws organizations list-delegated-administrators --service-principal=config.amazonaws.com
aws organizations list-delegated-administrators --service-principal=member.org.stacksets.cloudformation.amazonaws.com
You should see output similar to the following:
{
"DelegatedAdministrators": [
{
"Id": "MemberAccountID",
"Arn": "arn:aws:organizations::MemberAccountID:account/o-c7esubdi38/MemberAccountID",
"Email": "[email protected]",
"Name": "name",
"Status": "ACTIVE",
"JoinedMethod": "INVITED",
"JoinedTimestamp": 1604867734.48,
"DelegationEnabledDate": 1607020986.801
}
]
}
You can validate the following IAM Roles created on your AWS Member Accounts:
- AWSServiceRoleForConfig
- AWSServiceRoleForConfigMultiAccountSetup
- AWSServiceRoleForCloudFormationStackSetsOrgMember
## Step 2. Establish AWS Config Recorders using CloudFormation StackSets.
Before setting up Config Rules, it is necessary to begin recording resource changes, which requires the creation of a Configuration Recorder in each member account of our Organization.
There are various methods to activate AWS Config across multiple accounts; however, in this lab, we will utilize AWS CloudFormation StackSets to centrally manage Config Recorders from the Delegated Admin Account. We will also employ a Service-managed StackSet to automatically generate the required IAM Roles, prefixed with "stacksets-exec."
AWS offers various CloudFormation templates for AWS Config; however, we will utilize the template named [EnableAWSConfigForOrganizations.yml](https://cloudformation-stackset-sample-templates-us-east-1.s3.us-east-1.amazonaws.com/EnableAWSConfigForOrganizations.yml).
You can review the entire file to see all the functionalities the template supports. In this lab, we will concentrate on the following resources:
- Configuration Recorder to record all resource types (or to filter the resource types you prefer)
- Delivery Channel to send Config History and Config Snapshot files to S3, and optionally to SNS

I have developed a CloudFormation template that implements our StackSet for enabling AWS Config on all accounts, thereby automating its creation via the AWS CLI. The template includes the following functionalities:
- Creation of a new S3 Bucket exclusively for centralized AWS Config logging.
- Implementation of the StackSet across all our organization accounts, with the Delivery Channel set up to relay logs to the centralized S3 Bucket.
Please review the entire template and make any necessary modifications as needed.

Following the successful creation of the Stack, you may proceed to verify the establishment of the following resources:
_CloudFormation Stack in Delegated Admin account_
_S3 Bucket in Delegated Admin account_
_CloudFormation StackSet in Delegated Admin account_
_CloudFormation Stacks in Member Accounts_
_IAM Role for Service-managed StackSet in Member Accounts_
_AWS Config enabled in Member Accounts_
## Step 3. Implement Organization Config Rules across all accounts.
Next, we will deploy a few Organization Config Rules. You can explore all the available [Managed Rules](https://docs.aws.amazon.com/config/latest/developerguide/managed-rules-by-aws-config.html) or create your Custom Rules. For this lab, we will use the ACCESS_KEYS_ROTATED and REQUIRED_TAGS rules to fit my use case.
It should be noted that Organization Config Rules are automatically deployed to the Management Account. However, during Step 2, when the StackSet was deployed to activate Config, it did not include the Management Account. Therefore, if you wish to set up Config for the Management Account, you must first manually activate Config and then establish the necessary Service-Linked accounts using these commands:
aws iam create-service-linked-role --aws-service-name config.amazonaws.com
aws iam create-service-linked-role --aws-service-name config-multiaccountsetup.amazonaws.com
For simplicity, we will not deploy Config Rules to the Management Account. Therefore, we will include an additional parameter "ExcludedAccounts" with the Management account ID as its value to prevent the creation of Config Rules in that account.
Please review the following template and make any necessary modifications as needed.

MaximumExecutionFrequency: TwentyFour_Hours
Upload the new template to S3 and run the following command for creating the stack.
aws cloudformation create-stack --stack-name Config-OrgConfigRules \
--template-url https://xxxxxxxx-templates.s3.amazonaws.com/3-StackSetConfigRules.yml \
--parameters \
ParameterKey=TagName,ParameterValue=Config-StackSetConfigRecorder \
ParameterKey=TagUnit,ParameterValue=Security \
ParameterKey=TagEnvironment,ParameterValue=Prod \
ParameterKey=OrgRulePrefixName,ParameterValue="compliance" \
ParameterKey=OrgRuleExcludedAccounts,ParameterValue="XXXXXXXXXXXXX"
After successfully creating the Stack, you can confirm the establishment of the Config Rules in the Member Accounts:
_List Organization Config Rules using the CLI_
aws configservice describe-organization-config-rules
_List Organization Config Rules using the Console_
## Step 4. Set up an AWS Aggregator for cross-account reporting.
Now that we've implemented some Config Rules, it's necessary to have a straightforward method to monitor compliance across all accounts, which is why we are proceeding to establish our Config Aggregator.
We will create a final stack to deploy the Config Aggregator, along with a new IAM Role that the Aggregator needs to gather data from all accounts within an organization.
Please review the following template and make any necessary modifications as needed.

Upload the new template to S3 and run the following command to create the stack.
aws cloudformation create-stack --stack-name Config-OrgConfigAggregator \
--template-url https://xxxxxxxx-templates.s3.amazonaws.com/4-StackSetConfigAgg.yml \

ParameterKey=TagUnit,ParameterValue=Security \
ParameterKey=TagEnvironment,ParameterValue=Prod \
ParameterKey=ConfigAggRoleName,ParameterValue="ConfigAggregatorRole" \
ParameterKey=ConfigAggName,ParameterValue="aggregator"
Once the command is executed successfully, an 'OK' status will appear on the aggregator page. However, the aggregator dashboard may take a while to reflect the data from all accounts.
You can execute a query in the Console utilizing data from all accounts and examine all the available fields. To view data from all S3 buckets, run the following query.
SELECT
resourceId,
resourceName,
resourceCreationTime,
accountId
WHERE
resourceType = 'AWS::S3::Bucket'
## Cleanup
This lab outlined enabling AWS Config using the AWS CLI to easily replicate each setting. It's important to remember to clean up all CloudFormation stacks and any IAM Role created by AWS.
## Further steps
If you're interested in further exploring AWS Config features and enhancing your setup, consider these suggestions:
- Implement Conformance Packs to utilize a single template that establishes Config Rules across all accounts, avoiding the constraints of Organization Config Rules that necessitate individual rule definition.
- Extend the scope of AWS Config to a multi-region setting within AWS Organizations.
- Introduce server-side encryption for the Centralized S3 Bucket using KMS, which will entail adding IAM Policies to numerous IAM Roles.
- Experiment with AWS Control Tower, a service that simplifies many of the manual configurations associated with AWS Config.
- Implement SNS Notifications for the Config Delivery channel to centralize all messages into one account.
