Controls that enhance data residency protection

These elective controls complement your enterprise's data residency posture. By applying these controls together, you can set up your multi-account environment to help detect and inhibit the purposeful or accidental creation, sharing, or copying of data, outside of your selected AWS Region or Regions.

These controls take effect at the OU level, and they apply to all member accounts within the OU.

Important

Certain global AWS services, such as AWS Identity and Access Management (IAM) and AWS Organizations, are exempt from these controls. You can identify the services that are exempt by reviewing the Region deny SCP, shown in the example code. Services with "*" after their identifier are exempt, because all actions are permitted when the "*" notation is given. This SCP essentially contains a list of explicitly permitted actions, and all other actions are denied. You cannot deny access to your home Region.

Video: Enable data residency controls

This video (5:58) describes how to enable data residency controls with AWS Control Tower controls. For better viewing, select the icon at the lower right corner of the video to enlarge it to full screen. Captioning is available.

Note

AWS Control Tower no longer supports searching the controls list by Category, as shown in this video. To easily identify the Data Residency controls, we recommend you sort the controls list by Release Date. Controls with a release date of November 30, 2021 are the same controls in the Data Residency category shown in the video.

This video includes the term guardrail, an older term AWS Control Tower used for control. We updated the term to better align with industry usage and other AWS services. These terms are synonymous for our purposes.

Disallow internet access for an Amazon VPC instance managed by a customer

This control disallows internet access for an Amazon Virtual Private Cloud (VPC) instance managed by a customer, rather than by an AWS service.

Important

If you provision Account Factory accounts with VPC internet access settings enabled, that Account Factory setting overrides this control. To avoid enabling internet access for newly provisioned accounts, you must change the setting in Account Factory. For more information, see Configure AWS Control Tower Without a VPC.

This control does not apply to VPCs managed by AWS services.
Existing VPCs that have internet access retain their internet access. It applies to new instances only. After this control is applied, access cannot be changed.

This is a preventive control with elective guidance. By default, this control isn't enabled on any OUs.

The artifact for this control is the following service control policy (SCP).

Disallow cross-region networking for Amazon EC2, Amazon CloudFront, and AWS Global Accelerator

This control prevents configuring cross-region networking connections from Amazon EC2, Amazon CloudFront, and AWS Global Accelerator services. It prevents VPC peering and transit gateway peering.

Note

This control prevents Amazon EC2 VPC peering and Amazon EC2 transit gateway peering within a single Region, as well as across Regions. For this reason, this control may affect certain workloads in addition to your data residency posture.

This is a preventive control with elective guidance. By default, this control isn't enabled on any OUs.
