Access control

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

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

IAM lets you 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. For example, a particular user might need to create and modify Domain Name System (DNS) record resources. You would then give that user (who) the /roles/dns.admin role, which has the dns.changes.create and dns.resourceRecordSets.create permissions (what) so that they can create and update resource record sets (which). On the other hand, a support department may only need to view existing resource record sets, so they would get a /roles/dns.reader role.

Permissions and roles

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

Permissions

The following table lists the permissions that the caller must have to call each method.

Method Required permission(s)
dns.changes.create for creating a resource record set. dns.changes.create and dns.resourceRecordSets.create on the project containing the record set.
dns.changes.create for updating a resource record set. dns.changes.create and dns.resourceRecordSets.update on the project containing the record set.
dns.changes.create for deleting a resource record set. dns.changes.create and dns.resourceRecordSets.delete on the project containing the record set.
dns.changes.get dns.changes.get for the project containing the managed zone.
dns.changes.list dns.changes.list for the project containing the managed zone.
dns.dnsKeys.get dns.dnsKeys.get for the project containing the managed zone.
dns.dnsKeys.list dns.dnsKeys.list for the project containing the managed zone.
dns.managedZoneOperations.get dns.managedZoneOperations.get for the project containing the managed zone.
dns.managedZoneOperations.list dns.managedZoneOperations.list for the project containing the managed zone.
dns.managedZones.create dns.managedZones.create for the project containing the managed zone.

If creating a private zone, you also need dns.networks.bindPrivateDNSZone and dns.networks.targetWithPeeringZone for each project containing each VPC network that you authorize to access the zone.
dns.managedZones.delete dns.managedZones.delete for the project containing the managed zone.
dns.managedZones.get dns.managedZones.get for the project containing the managed zone.
dns.managedZones.list dns.managedZones.list for the project containing the managed zone.
dns.managedZones.update dns.managedZones.update for the project containing the managed zone.

If creating a private zone, you also need dns.networks.bindPrivateDNSZone and dns.networks.targetWithPeeringZone for each project containing each VPC network that you authorize to access the zone.
dns.policies.create dns.policies.create for the project containing the policy.

If the policy is created on a VPC network, you also need dns.networks.bindPrivateDNSPolicy for each project containing each VPC network.
dns.policies.delete dns.policies.delete for the project containing the policy.
dns.policies.get dns.policies.get for the project containing the policy.
dns.policies.list dns.policies.list for the project containing the policy.
dns.policies.update dns.policies.update for the project containing the policy.

If the policy is updated to be on a VPC network, you also need dns.networks.bindPrivateDNSPolicy for each project containing each VPC network.
dns.policies.patch dns.policies.patch for the project containing the policy.
dns.projects.get dns.projects.get for the project.
dns.resourceRecordSets.list dns.resourceRecordSets.list for the project containing the managed zone.

Roles

The following table lists the Cloud DNS API IAM roles with a corresponding list of all the permissions that each role includes. Every permission is applicable to a particular resource type.

You can also use basic roles to make DNS changes.

Managing access control

You can use the Google Cloud Console to manage access control for your topics and projects.

To set access controls at the project level, follow these steps.

Console

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

    Go to the IAM page

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

  3. Click Add.

  4. In New members, enter the email address of a new member.

  5. Select the desired role from the drop-down menu.

  6. Click Save.

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