Access control with IAM

Google Cloud offers Identity and Access Management (IAM), which enables you to give more granular access to specific Google Cloud resources and prevents unwanted access to other resources. This page describes the Service Directory API roles. For a detailed description of IAM, read the IAM documentation.

IAM enables you to adopt the security principle of least privilege, so you grant only the necessary access to your resources.

IAM enables you to control who has what permissions to which resources by setting IAM policies. IAM policies grant specific roles to a user, giving the user certain permissions.

Permissions and Roles

Every Service Directory API method requires the caller to have the necessary IAM permissions. You can assign permissions by granting roles to a user, group, or service account. In addition to the basic Owner, Editor, and Viewer roles, you can grant Service Directory API roles to the users of your project.

Permissions

You can find out which permissions are required for each method in the Service Directory API reference documentation.

Access Control using the Google Cloud console

You can use the Google Cloud console to manage access control for your registry.

To set access controls at the project level:

Console

  1. In the Google Cloud console, go to the IAM page.

    Go to IAM

  2. Select your project from the top pull-down menu.

  3. Click Add.

  4. In New principals, enter the email address of a new principal.

  5. Select the desired role from the drop-down menu: servicedirectory.admin, servicedirectory.editor, or servicedirectory.viewer

  6. Click Save.

  7. Verify that the principal is listed with the role that you granted.

Service Directory zones override IAM restrictions

When assigning a namespace to a Service Directory zone, the service names become visible to all clients on any networks that are authorized to query the private zone. There is no IAM access control for DNS as the DNS protocol does not provide authentication capability.
