Restrict data transfers across AWS Regions - AWS Prescriptive Guidance

Restrict data transfers across AWS Regions

We would love to hear from you. Please provide feedback on the AWS PRA by taking a short survey.

With the exception of two AWS Identity and Access Management (IAM) roles, this service control policy denies API calls to regional AWS services in AWS Regions other than eu-west-1 and eu-central-1. This SCP can help prevent the creation of AWS storage and processing services in unapproved Regions. This can help prevent personal data from being handled by AWS services in those Regions altogether. This policy uses a NotAction parameter because it accounts for global AWS services, such as IAM, and services that integrate with global services, such as AWS Key Management Service (AWS KMS) and Amazon CloudFront. In the parameter values, you can specify those global and other non-applicable services as exceptions. For more information about how this policy can help protect privacy and personal data in your organization, see AWS Organizations in this guide.
