Roles and permissions

This page describes the Identity and Access Management (IAM) roles and permissions needed to use Network Connectivity Center.

At a high level, you need the following:

• Predefined Network Connectivity Center permissions, which are described in Predefined roles.
• Additional permissions as follows:
  • To create spokes, you need permission to read the relevant spoke resource types, as described in Permission to create a spoke.
  • To work with Network Connectivity Center in the Google Cloud console, you need permission to view certain Virtual Private Cloud (VPC) network resources, as described in Permission to use Network Connectivity Center in the Google Cloud console.

Be aware that if you need to work with Network Connectivity Center in a Shared VPC network, you must have all needed permissions in the host project. A hub, its spokes, and all related resources must be in the host project.

For information about how to grant permissions, see the IAM overview.

Note: To create spokes, you also need permission to read your spoke's resource type, as described in Permission to create a spoke. If you plan to work in the Google Cloud console, you also need the permissions described in Permission to use Network Connectivity Center in the Google Cloud console.

Additional required permissions

Depending on what actions you need to take in Network Connectivity Center, you might need the permissions described in the following sections.

Permission to create a spoke

To create a spoke, you must have permission to read the spoke's resource type. For example:

• For VPN tunnel spokes, VLAN attachment spokes, and Router appliance spokes, you need compute.routers.get.
• To create Router appliance spokes, you need compute.instances.get. Also, before you can use a Router appliance spoke, you must set up peering between the Cloud Router and the router appliance instance. To establish peering, you need the following permissions:
  • compute.instances.use
  • compute.routers.update
• To create VLAN attachment spokes, you need compute.interconnectAttachments.get.
• To create VPN tunnel spokes, you need compute.vpnTunnels.get.

• To create VPC spokes, you need the following permissions:

  • compute.networks.use
  • compute.networks.get

• To create VPC spokes in a different project from the hub that it is associated with, you need networkconnectivity.groups.use.

Permission to use Network Connectivity Center in the Google Cloud console

To use Network Connectivity Center in the Google Cloud console, you need a role—such as Compute Network Viewer (roles/compute.networkViewer)—that includes the permissions described in the following table. To use these permissions, you must first create a custom role.

Task	Required permissions
Access the Network Connectivity Center page	compute.projects.get compute.networks.get
Access and use the Add spokes page	compute.networks.list compute.regions.list compute.routers.list compute.zones.list compute.networks.get
Add a VLAN attachment spoke	compute.interconnectAttachments.list compute.interconnectAttachments.get compute.networks.get compute.routers.list compute.routers.get
Add a VPN tunnel spoke	compute.forwardingRules.list compute.networks.get compute.routers.get compute.routers.list compute.targetVpnGateways.list compute.vpnGateways.list compute.vpnTunnels.get compute.vpnTunnels.list
Add a Router appliance spoke	compute.instances.list compute.instances.get compute.networks.get
Add a VPC spoke	compute.networks.use compute.networks.get compute.subnetworks.list

Note: To create spokes, you also need permission to read the resource types used by your spokes, as described in Permission to create a spoke.

Protecting resources with VPC Service Controls

To further secure your Network Connectivity Center resources, use VPC Service Controls.

VPC Service Controls provides your resources with additional security to help mitigate the risk of data exfiltration. By using VPC Service Controls, you can place Network Connectivity Center resources within service perimeters. VPC Service Controls then protects these resources from requests that originate outside the perimeter.

To learn more about service perimeters, see the Service perimeter configuration page of the VPC Service Controls documentation.
