The requirement includesremediating existing noncompliant bucketsand also handlingfuture noncompliant bucketsacross multiple accounts and Regions. Anorganization-wide AWS Config aggregatorprovides centralized visibility into compliance status across all member accounts/Regions. To remediate, AWS Config can trigger automation (commonly via EventBridge/SNS) that invokes anAWS Lambda function(or SSM Automation) to take corrective action—such as enabling default encryption, blocking public access, or applying required bucket policies—whenever a bucket is evaluated as noncompliant. This addresses both existing findings (by running remediation on current noncompliant resources) and new ones (by automatically reacting when new buckets appear or configurations drift).

Options C and D are insufficient because they scope only to “accounts and Regions the company currently uses,” which fails the multi-Region/multi-account organization requirement and would miss future expansion. Option B helps prevent creation of new noncompliant resources but does not remediate existing buckets, which is explicitly required. Therefore, the combination of an org-wide aggregator plus automated remediation on Config noncompliance is the best fit.

AWS Organizations and CloudFormation StackSets provide an organizational deployment mechanism for consistent infrastructure across accounts. AWS Certified Security – Specialty guidance emphasizes minimizing use of the management account and using delegated administrator capabilities where available for centralized governance while reducing blast radius. By configuring a delegated administrator account for AWS CloudFormation, the company can create and manage StackSets without performing day-to-day deployment operations from the management account. Targeting the organization root ensures the StackSet deploys to all existing accounts. Enabling automatic deployment ensures that any future accounts that join the organization (or move into targeted OUs, depending on configuration) automatically receive the monitoring service without manual intervention. This directly meets the requirement to deploy to all existing and future accounts with minimal effort. Option A requires ongoing manual updates when accounts are added, increasing operational overhead. Options C and D rely on Systems Manager Automation, which can work but introduces additional operational complexity and is not the standard AWS mechanism for organization-wide infrastructure rollout compared to StackSets with auto-deployment. StackSets also provide consistent change control, drift detection, and centralized update mechanisms, which align with governance expectations for compliance tooling.

For centralized, organization-wide user access to AWS services and supported applications, AWS best practice is to useAWS IAM Identity Center(successor to AWS SSO). IAM Identity Center provides a single place to manage workforce identities, permission sets, and account assignments across AWS Organizations. Amazon Q Developer is integrated for centralized access using IAM Identity Center, where you can assign the relevant permissions to users and groups and enable access consistently across multiple AWS accounts. Setting Amazon Q Developer up as anAWS managed applicationaligns with IAM Identity Center’s model for centrally provisioning and controlling access with minimal operational overhead.

Amazon Cognito is primarily intended forcustomer identity and application sign-up/sign-inscenarios, not for workforce access to AWS managed developer tools across multiple AWS accounts. “Identity pools” are a Cognito concept for exchanging identities for AWS credentials, which adds unnecessary complexity and is not the standard approach for centrally granting employees access to Amazon Q Developer in an organization. Therefore, enabling IAM Identity Center and configuring Amazon Q Developer as an AWS managed application is the correct solution.
