Secured Data Warehouse On-premisses Data Ingestion Blueprint

FAQ | Troubleshooting Guide.

This repository contains Terraform configuration modules that allow Google Cloud customers to import data from an on-premises environment or another cloud into a Secured BigQuery warehouse. This blueprint provides an opinionated architecture and an example on how to:

  • Encrypt data located outside of Google Cloud and import it into BigQuery using the Tink library.
  • Configure VPC Service Controls to secure the data pipeline and access to confidential data.
  • Configure separation of duties for personas (Google Groups).
  • Set up appropriate security controls (Organization Policies) and Google Cloud Logging to help protect confidential data.
  • Use data classification, Data Catalog policy tags, dynamic data masking, and column-level encryption to restrict access to specific columns in the BigQuery data warehouse.

Disclaimer

When using this blueprint, it is important to understand how you manage [separation of duties](https://cloud.google.com/kms/docs/separation-of-duties. We recommend you remove all primitive owner roles in the projects used as inputs for the blueprint main module. The blueprint itself does not need any primitive owner roles for correct operations. The Blueprint does not proactively remove any pre-existing owner role assignments from pre-existing projects in your organization, as we won’t know your intent for or dependency on these role assignments in your pre-existing workloads. The pre-existing presence of these roles does expand the attack and risk surface of the resulting deployment. Therefore, we highly recommend you review your use of owner roles in these pre-existing cases and see if you can eliminate them to improve your resulting security posture.

You can check the current situation of your project with either of the following methods:

See the terraform-example-foundation for additional good practices.

Usage

Basic usage of this module is as follows:

module "secured_data_warehouse" {
  source  = "GoogleCloudPlatform/secured-data-warehouse-onprem-ingest/google"
  version = "~> 0.1"

  org_id                           = ORG_ID
  data_governance_project_id       = DATA_GOVERNANCE_PROJECT_ID
  data_governance_project_number   = DATA_GOVERNANCE_PROJECT_NUMBER
  data_project_id                  = DATA_PROJECT_ID
  data_project_number              = DATA_PROJECT_NUMBER
  data_ingestion_project_id        = DATA_INGESTION_PROJECT_ID

  sdx_project_number               = EXTERNAL_TEMPLATE_PROJECT_NUMBER
  terraform_service_account        = TERRAFORM_SERVICE_ACCOUNT
  access_context_manager_policy_id = ACCESS_CONTEXT_MANAGER_POLICY_ID
  bucket_name                      = DATA_INGESTION_BUCKET_NAME
  pubsub_resource_location         = PUBSUB_RESOURCE_LOCATION
  location                         = LOCATION
  trusted_locations                = TRUSTED_LOCATIONS
  dataset_id                       = DATASET_ID
  cmek_keyring_name                = CMEK_KEYRING_NAME
  perimeter_additional_members     = PERIMETER_ADDITIONAL_MEMBERS
  data_engineer_group              = DATA_ENGINEER_GROUP
  data_analyst_group               = DATA_ANALYST_GROUP
  security_analyst_group           = SECURITY_ANALYST_GROUP
  network_administrator_group      = NETWORK_ADMINISTRATOR_GROUP
  security_administrator_group     = SECURITY_ADMINISTRATOR_GROUP
  encrypted_data_reader_group      = ENCRYPTED_DATA_READER_GROUP
  plaintext_reader_group           = PLAINTEXT_READER_GROUP
  delete_contents_on_destroy       = false
}

Note: There are three inputs related to GCP Locations in the module:

  • pubsub_resource_location: is used to define which GCP location will be used to Restrict Pub/Sub resource locations. This policy offers a way to ensure that messages published to a topic are never persisted outside of a Google Cloud regions you specify, regardless of where the publish requests originate. Zones or multi-region locations are not supported.
  • location: is used to define which GCP region will be used for all other resources created: Cloud Storage buckets, BigQuery datasets, and Cloud KMS key rings. Multi-region locations are supported.
  • trusted_locations: is a list of locations that are used to set an Organization Policy that restricts the GCP locations that can be used in the projects of the Secured Data Warehouse. Both pubsub_resource_location and location must respect this restriction.

A Functional example, deploying the module, the required infrastructure needed by the module, and data to be ingested is included in the examples directory.

Additional information related to the inputs and outputs of the module are detailed in the following section.

Requirements

These sections describe requirements for using this blueprint.

Note: Please see the Disclaimer regarding project owners before creating projects.

Software

The following dependencies must be available:

Security Groups

Provide the following groups for separation of duty. Each group will be granted roles to perform their tasks. Add users to the appropriate groups as needed.

  • Data Engineer group: Google Cloud IAM group that sets up and maintains the data pipeline and warehouse.
  • Data Analyst group: Google Cloud IAM group that analyzes the data in the warehouse.
  • Security Analyst group: Google Cloud IAM group that monitors and responds to security incidents.
  • Network Administrator group: Google Cloud IAM group that reviews network configuration. Typically, this includes members of the networking team.
  • Security Administrator group: Google Cloud IAM group that administers security configurations in the organization(org policies, KMS, VPC service perimeter).
  • Encrypted Data Reader Group: Google Cloud IAM group that analyzes encrypted data.
  • Plain Text Reader Group: Google Cloud IAM group that analyzes plaintext reader.

Groups can be created in the Google Workspace Admin Console, in the Google Cloud Console, or using gcloud identity groups create command.

Note 1: Groups Data Engineer and Data Analyst are granted the role "Service Account User" on the Dataflow controller service account, the one in the dataflow_controller_service_account_email output. This is required to be able to run dataflow jobs in the Data Ingestion project.

See the Dataflow Jobs Deployment documentation for additional information on deploying Dataflow Jobs.

Note 2: The group Plain Text Reader Group is the only group tha should be granted access to the KMS keys used to encrypt the data.

    • Organization Policy Administrator: roles/orgpolicy.policyAdmin
    • Organization Administrator: roles/resourcemanager.organizationAdmin
