Ensure that Corporate Login Credentials are Used

MediumLevel 1Manual reviewgcp

Description

Use corporate login credentials instead of consumer accounts, such as Gmail accounts. It is recommended fully-managed corporate Google accounts be used for increased visibility, auditing, and controlling access to Cloud Platform resources. Email accounts based outside of the user's organization, such as consumer accounts, should not be used for business purposes.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

For each Google Cloud Platform project, list the accounts that have been granted access to that project: From Google Cloud CLI gcloud projects get-iam-policy PROJECT_ID Also list the accounts added on each folder: gcloud resource-manager folders get-iam-policy FOLDER_ID And list your organization's IAM policy: gcloud organizations get-iam-policy ORGANIZATION_ID No email accounts outside the organization domain should be granted permissions in the IAM policies. This excludes Google-owned service accounts.

How it is fixed

Fix method: Guidance or infrastructure patch

Remove all consumer Google accounts from IAM policies. Follow the documentation and setup corporate login accounts. Prevention: To ensure that no email addresses outside the organization can be granted IAM permissions to its Google Cloud projects, folders or organization, turn on the Organization Policy for Domain Restricted Sharing.
