Resource control policies (RCPs) are now available in the AWS GovCloud (US) Regions

Today, AWS Organizations is making resource control policies (RCPs) available in both AWS GovCloud (US-West) and AWS GovCloud (US-East) Regions. RCPs help you centrally establish a [data perimeter](https://aws.amazon.com/identity/data-perimeters-on-aws/) across your AWS environment. With RCPs, you can centrally restrict external access to your AWS resources at scale. RCPs are a type of authorization policy in AWS Organizations that you can use to centrally enforce the maximum available permissions for resources in your organization. For example, an RCP can help enforce the requirement that “no principal outside my organization can access Amazon S3 buckets in my organization,” regardless of the permissions granted through individual S3 bucket policies. For an updated list of AWS services that support RCPs, refer to the [list of services supporting RCPs](https://docs.aws.amazon.com/organizations/latest/userguide/orgs%5Fmanage%5Fpolicies%5Frcps.html#rcp-supported-services).
