Service Control Policies: Prevent Modifications to Specific CloudFormation Stacks

My Saved Presets

This SCP restricts IAM principals in accounts from making changes to specific CloudFormation stacks with the exception of a specific IAM role (This could be a common administrative IAM role created in all accounts in your organization)

See Related Configuration Items for a Configuration Package to deploy multiple SCPs to an AWS Account.

Configuration template includes a CloudFormation custom resource to deploy into an AWS account.
