Switzerland Regions control package

This page describes the set of controls that are applied on Switzerland Regions workloads in Assured Workloads. It provides detailed information about data residency, supported Google Cloud products and their API endpoints, and any applicable restrictions or limitations on those products. The following additional information applies to Switzerland Regions:

• Data residency: The Switzerland Regions control package sets data location controls to support Switzerland-only regions. See the Google Cloud-wide organization policy constraints section for more information.
• Support: Technical support services for Switzerland Regions workloads are available with Standard, Enhanced, or Premium Cloud Customer Care subscriptions. Switzerland Regions workloads support cases are routed to global support personnel.
• Pricing: The Switzerland Regions control package is included in Assured Workloads' Free tier, which incurs no additional charges. See Assured Workloads pricing for more information.

Supported products and API endpoints

Unless otherwise noted, users can access all supported products through the Google Cloud console. Restrictions or limitations that affect the features of a supported product, including those that are enforced through organization policy constraint settings, are listed in the following table.

If a product is not listed, that product is unsupported and has not met the control requirements for Switzerland Regions. Unsupported products are not recommended for use without due diligence and a thorough understanding of your responsibilities in the shared responsibility model. Before using an unsupported product, ensure that you are aware of and are willing to accept any associated risks involved, such as negative impacts to data residency or data sovereignty.

Restrictions and limitations

The following sections describe Google Cloud-wide or product-specific restrictions or limitations for features, including any organization policy constraints that are set by default on Switzerland Regions folders. Other applicable organization policy constraints —even if not set by default— can provide additional defense-in-depth to further protect your organization's Google Cloud resources.

Google Cloud-wide

Google Cloud-wide organization policy constraints

The following organization policy constraints apply across Google Cloud.

Organization policy constraint	Description
gcp.resourceLocations	Set to the following locations in the allowedValues list: europe-west6 This value restricts creation of new resources to the selected values. When set, no resources can be created in any other regions, multi-regions, or locations outside of the selection. See Resource locations supported services for a list of resources that can restricted by the Resource Locations organization policy constraint, as some resources may be out of scope and unrestrictable. Changing this value by making it less restrictive potentially undermines data residency by allowing data to be created or stored outside of a compliant data boundary.
gcp.restrictServiceUsage	Set to allow all supported products and API endpoints. Determines which services can be used by restricting runtime access to their resources. For more information, see Restricting resource usage.
gcp.restrictTLSVersion	Set to deny the following TLS versions: TLS_1_0 TLS_1_1 See the Restrict TLS versions page for more information.

BigQuery

Affected BigQuery features

Feature	Description
Enabling BigQuery on a new folder	BigQuery is supported, but it isn't automatically enabled when you create a new Assured Workloads folder due to an internal configuration process. This process normally finishes in ten minutes, but can take much longer in some circumstances. To check whether the process is finished and to enable BigQuery, complete following steps: In the Google Cloud console, go to the Assured Workloads page. Go to Assured Workloads Select your new Assured Workloads folder from the list. On the Folder Details page in the Allowed services section, click Review Available Updates. In the Allowed services pane, review the services to be added to the Resource Usage Restriction organization policy for the folder. If BigQuery services are listed, click Allow Services to add them. If BigQuery services are not listed, wait for the internal process to complete. If the services are not listed within 12 hours of folder creation, contact Cloud Customer Care. After the enablement process is completed, you can use BigQuery in your Assured Workloads folder. Gemini in BigQuery is not supported by Assured Workloads.
Unsupported features	The following BigQuery features are not supported and should not be used in the BigQuery CLI. It is your responsibility not to use them in BigQuery for Assured Workloads. Interaction with remote data sources Externally-trained BQML models are not supported. Internally-trained BQML models are supported. Dynamic data masking GDrive export Remote functions Saved queries Workflow scheduling For BigQuery Studio, notebooks are unsupported. Gemini in BigQuery is not supported.
BigQuery CLI	The BigQuery CLI is supported.
Google Cloud SDK	You must use Google Cloud SDK version 403.0.0 or newer to maintain data regionalization guarantees for technical data. To verify your current Google Cloud SDK version, run gcloud --version and then gcloud components update to update to the newest version.
Administrator controls	BigQuery will disable unsupported APIs but administrators with sufficient permissions to create an Assured Workloads folder can enable an unsupported API. If this occurs, you will be notified of potential non-compliance through the Assured Workloads monitoring dashboard.
Loading data	BigQuery Data Transfer Service connectors for Google Software as a Service (SaaS) apps, external cloud storage providers, and data warehouses are not supported. It is your responsibility not to use BigQuery Data Transfer Service connectors for Switzerland Regions workloads.
Third-party transfers	BigQuery does not verify support for third-party transfers for the BigQuery Data Transfer Service. It is your responsibility to verify support when using any third-party transfer for the BigQuery Data Transfer Service.
Non-compliant BQML models	Externally-trained BQML models are not supported.
Query jobs	Query jobs should only be created within Assured Workloads folders.
Queries on datasets in other projects	BigQuery does not prevent Assured Workloads datasets from being queried from non-Assured Workloads projects. You should ensure that any query that has a read or a join on Assured Workloads data be placed in an Assured Workloads folder. You can specify a fully-qualified table name for their query result using projectname.dataset.table in the BigQuery CLI.
Cloud Logging	BigQuery utilizes Cloud Logging for some of your log data. You should disable your _default logging buckets or restrict _default buckets to in-scope regions to maintain compliance using the following command: gcloud alpha logging settings update --organization=ORGANIZATION_ID --disable-default-sink See Regionalize your logs for more information.

Compute Engine

Affected Compute Engine features

Feature

Description

Guest environment

It is possible for scripts, daemons, and binaries that are included with the guest environment to access unencrypted at-rest and in-use data. Depending on your VM configuration, updates to this software may be installed by default. See Guest environment for specific information about each package's contents, source code, and more. These components help you meet data sovereignty through internal security controls and processes. However, if you want additional control, you can also curate your own images or agents and optionally use the compute.trustedImageProjects organization policy constraint. See the Building a custom image page for more information.

Compute Engine organization policy constraints

Organization policy constraint	Description
compute.disableGlobalCloudArmorPolicy	Set to True. Disables the creation of new global Google Cloud Armor security policies, and the addition or modification of rules to existing global Google Cloud Armor security policies. This constraint doesn't restrict the removal of rules or the ability to remove or change the description and listing of global Google Cloud Armor security policies. Regional Google Cloud Armor security policies are unaffected by this constraint. All global and regional security policies that exist prior to the enforcement of this constraint remain in effect.
compute.restrictNonConfidentialComputing	(Optional) Value is not set. Set this value to provide additional defense-in-depth. See the Confidential VM documentation for more information.
compute.trustedImageProjects	(Optional) Value is not set. Set this value to provide additional defense-in-depth. Setting this value constrains image storage and disk instantiation to the specified list of projects. This value affects data sovereignty by preventing use of any unauthorized images or agents.

Cloud Logging

Affected Cloud Logging features

Feature	Description
Log sinks	Filters shouldn't contain Customer Data. Log sinks include filters which are stored as configuration. Don't create filters that contain Customer Data.
Live tailing log entries	Filters shouldn't contain Customer Data. A live tailing session includes a filter which is stored as configuration. Tailing logs doesn't store any log entry data itself, but can query and transmit data across regions. Don't create filters that contain Customer Data.
