Introduction

There are certain prerequisites that need to be set up in your GCP account before it can be onboarded into CoreStack and used for CoreStack Assessments.

While the specific steps vary depending on which type of cloud account you want to onboard from GCP, in general for GCP Projects you will have to create either a user account or service account for CoreStack and then provide appropriate roles for the user account or service account for the Assessment + Governance option.

In this user guide, we'll cover the different steps you need to follow to properly configure the prerequisites in your GCP cloud account(s) based on which type of account(s) you're onboarding.

Prerequisites for GCP Billing Accounts

GCP Projects can be onboarded as a Billing Account in CoreStack. Onboarding a Billing Account allows you to discover the cost information of all its linked GCP Projects.

However, before your GCP project can be onboarded into CoreStack, there are certain prerequisites that need to be met.

Set Up Cloud Billing Data Export to BigQuery:

To enable your Cloud Billing usage costs and/or pricing data to be exported to BigQuery, please do the following:

  1. in the Google Cloud console, go to the Billing export page.

  2. Click to select the cloud Billing account for which you would like to export the billing data. The Billing export page opens for the selected billing account.

  3. On the BigQuery export tab, click Edit settings for each type of data you'd like to export. Each type of data is configured separately.

  4. From the Projects list, select the project that you set up which will contain your BigQuery dataset.

    The project you select is used to store the exported Cloud Billing data in the BigQuery dataset.

  5. From the Dataset ID field, select the dataset that you set up which will contain your exported Cloud Billing data.

    For all types of Cloud Billing data exported to BigQuery, the following applies:

    • The BigQuery API is required to export data to BigQuery. If the project you selected doesn't have the BigQuery API enabled, you will be prompted to enable it. Click Enable BigQuery API to enable the API.

    • If the project you selected doesn't contain any BigQuery datasets, you will be prompted to create one. If necessary, follow these steps to create a new dataset.

    • If you use an existing dataset, review the limitations that might impact exporting your billing data to BigQuery, such as being unable to export data to datasets configured to use customer-managed key encryption.

      For pricing data export, the BigQuery Data Transfer Service API is required to export the data to BigQuery. If the project you selected doesn't have the BigQuery Data Transfer Service API enabled, you are prompted to enable it. If necessary, follow these steps to enable the API.

  6. Click Save.

GCP Project Permissions

The following permissions must be configured in your GCP Project before onboarding.

User Account Permissions:

  • A user account must be created in GCP with the following permissions:
    • Project Editor (View and Modify.)
    • Billing Account Admin (This is required for exporting the billing data to a BigQuery dataset. If the data is already exported, then this permission is not required.)
    • BigQuery Admin (If the BigQuery dataset exported is in a different project, you need this access to retrieve the BigQuery dataset name. )

    API Access:

    • In GCP, enable API Access for the Cloud Resource Manager API, Recommender API, Cloud Billing API, and Compute Engine API in the API & Services – Library screen.

    📘

    Automated Approach for GCP Billing Account Onboarding:

    Service Account Permissions:

    • A service account must be created in GCP with the following permissions:
      • Project Viewer (Read only).

      Billing Account Prerequisites:

      • Schedule queries must be created in the GCP BigQuery console.
      • Create a Bucket for a BigQuery data transfer (under the same GCP Project where BigQuery exists).

      📘

      Note:

      The Bucket, Dataset and Scheduled Query created should be in the same location for the schedule query to execute successfully.

      Bucket Name:

      1. Login to the GCP console.
      2. Navigate to the Storage - Browser screen.
      3. Click Create bucket. The Create bucket screen appears.
      4. Provide a unique value in the Name your bucket field along with the other details required to create the bucket.
      5. Click the Create button.
      6. Copy the value provided in the Name your bucket field.

      Schedule Queries in GCP

      Next, you need to schedule some queries in GCP. Navigate to the Schedule Query Page in the GCP console then follow the steps below:

      1. Login to the GCP console.
      2. Navigate to the GCP BigQuery console.
      3. On the left menu, click Schedule Queries. The schedule queries list appears.

      1. Click Create Schedule Queries located at the top of the page.

      Prerequisites for GCP Linked Projects - Organization/Folder Scope

      There are certain prerequisites that need to be set up in your GCP project before it can be onboarded into CoreStack.

      1. We need to onboard a GCP Billing account before proceeding to onboard the Linked project.
      2. All the costs will be fetched from the billing account and the metadata sync for all the projects linked to this billing account will take 24 hours to be completed.

      📘

      Note:

      • The sync of the cost data will take 24 hours to reflect in CoreStack.
      • We will be able to onboard the linked project account only after the sync is completed.

      Permissions

      The following permissions must be configured in your GCP Project before onboarding.

      API access:

      • Enable API Access for Cloud Resource Manager API, Security Command Center API, Recommender API, Cloud Pub/Sub API, Organization Policy API, Compute Engine API, Cloud SQL Admin API, and Monitoring API in the API & Services – Library screen.

      User account permissions:

      • A user account must be created with the following permissions:
        • For Assessment: Viewer (Read only).
        • For Assessment + Governance: Organization Administrator/Security Admin (View and Modify).

      Service account permissions:

      Assign the following permissions at the Organization level for the service account which was created earlier as part of onboarding of a billing account.

      For Assessment: Viewer at Organization level (Read only).

      For Assessment + Governance:

      • Viewer (Read only)
      • Security Center admin editor
      • Pub/Sub Admin
      • Monitoring editor
      • Logs Configuration writer
      • Compute Admin

      Security Command Center Access is required for configuring security vulnerabilities assessment and compliance.

      Operations and Inventory Access is required for creating activity templates and alerting configurations through logging and pub/sub based on the utilization data.

      Compute Admin Access is required for running most of the templates and blueprints from the CoreStack marketplace.

      📘

      Note:

      In the future, if there are any operations-related activities which need more permissions, please grant the service account the necessary permissions.

      📘

      Note:

      If threats and advanced security health analytics policies are required then the Security Command Center premium tier needs to be enabled.
