Introduction

As part of the GCP account preparation required before onboarding cloud accounts into CoreStack, you will need to create least privilege policies— individual policies that must be attached to your cross-account role that allow CoreStack to access the GCP data it needs in order to create its reports.

You can refer to the paths below with template provided based on the type of access you wish to provide for CoreStack after cloning a GitHub repo (https://github.com/corestacklabs/Onboarding_Templates.git):

  • FinOps: Onboarding_Templates/GCP/Assesment-module-proj/finops/
  • SecOps: Onboarding_Templates/GCP/Assesment-module-proj/secops/
  • CloudOps: Onboarding_Templates/GCP/Assesment-module-proj/cloudops/

Each least privilege policy provides the necessary permissions to enable core functions in the CoreStack application, and are listed below organized by product bundle:

Compliance Standards - GCP CAF		Allow CoreStack to run security policies against your cloud resources in order to get violations and remediate some of the violated resources.

Note: CoreStack can pull resources and run them against the CoreStack policy engine, but remediation of impacted resources requires write permissions.		compute.disks.list

Resource InventoryAllow CoreStack to pull resources from GCP in order to populate the resource inventory in the portal UI.

Note: To show your resources in the CoreStack resource inventory, the below actions must be performed:
• Associate Volume
• Attach Load Balancer
• Deprovision
• DetachLoadBalancer
• DisassociateVolume
• Extend Volume
• Modify Security Group
• Manage_Tags
• Remove Labels
• Resize
• Restart
• SetLabels
• Start
• Stop
• Update Labels

CoreStack will require a few more governance permissions to accomplish this.		appengine.applications.get

Note:

Some permissions listed in this guide are not applicable when creating a project-level custom role. Those permissions can be assigned to a custom role only when creating a custom role at the organization-level.

Choosing to skip the below permissions may result in the following effects:

  • billing.budgets.create: CoreStack won't be able to create a cloud-native budget through the main portal, whereas CoreStack budget alerts can still be configured.
  • billing.budgets.get/list: CoreStack won't be able to list a cloud-native budget through portal.
  • billing.budgets.update: CoreStack won't be able to update cloud-native budgets through the main portal.
  • resourcemanager.folders.get/list: CoreStack won't be able to pull the folders listed as part of an organization.
  • securitycenter.subscription.get: CoreStack won't be able to identify the Security Command Center subscription details. This is needed for access validation to configure threats.
