Access management in Yandex IoT Core

In this section, you will learn:

• Which resources you can assign a role for.
• Which roles exist in the service.

About access managementAbout access management

In Yandex Cloud, all transactions are checked in Yandex Identity and Access Management. If a subject does not have the required permission, the service returns an error.

To grant permissions for a resource, assign roles for this resource to the subject that will perform the operations. You can assign roles to a Yandex account, service account, federated users, user group, system group, or public group. For more information, see How access management works in Yandex Cloud.

Roles for a resource can be assigned by users who have at least one of the following roles for that resource:

• admin
• resource-manager.admin
• organization-manager.admin
• resource-manager.clouds.owner
• organization-manager.organizations.owner

Which resources you can assign a role forWhich resources you can assign a role for

You can assign a role for a cloud or folder. These roles also apply to nested resources.

The list below shows all roles considered when verifying access permissions in Yandex IoT Core.

Service rolesService roles

iot.devices.writeriot.devices.writer

The iot.devices.writer role grants permission to send gRPC messages to Yandex IoT Core on behalf of a device.

iot.registries.writeriot.registries.writer

The iot.registries.writer role grants permission to send gRPC messages to Yandex IoT Core on behalf of a registry.

iot.auditoriot.auditor

The iot.auditor role allows you to view metadata about devices and device registries, as well as brokers and quotas in Yandex IoT Core.

iot.vieweriot.viewer

The iot.viewer role allows you to view all Yandex IoT Core resources.

iot.editoriot.editor

The iot.editor role allows users to create, edit, and delete all Yandex IoT Core resources.

For more information about service roles, see Roles in the Yandex Identity and Access Management service documentation.

Primitive rolesPrimitive roles

Primitive roles allow users to perform actions in all Yandex Cloud services.

auditorauditor

The auditor role grants a permission to read configuration and metadata of any Yandex Cloud resources without any access to data.

For instance, users with this role can:

• View info on a resource.
• View the resource metadata.
• View the list of operations with a resource.

auditor is the most secure role that does not grant any access to the service data. This role suits the users who need minimum access to the Yandex Cloud resources.

viewerviewer

The viewer role grants the permissions to read the info on any Yandex Cloud resources.

This role also includes the auditor permissions.

Unlike auditor, the viewer role provides access to service data in read mode.

editoreditor

The editor role provides permissions to manage any Yandex Cloud resources, except for assigning roles to other users, transferring organization ownership, removing an organization, and deleting Key Management Service encryption keys.

For instance, users with this role can create, modify, and delete resources.

This role also includes the viewer permissions.

adminadmin

The admin role enables assigning any roles, except for resource-manager.clouds.owner and organization-manager.organizations.owner, and provides permissions to manage any Yandex Cloud resources (except for transferring organization ownership and removing an organization).

Prior to assigning the admin role for an organization, cloud, or billing account, make sure to check out the information on protecting privileged accounts.

This role also includes the editor permissions.

Instead of primitive roles, we recommend using service roles. This ensures more selective access control and implementation of the principle of least privilege.

For more information about primitive roles, see the Yandex Cloud role reference.
