Access management in Data Streams

Data Streams uses roles to manage access rights.

Yandex Cloud users can only perform operations on resources that are allowed by the roles assigned to them. As long as a user has no roles assigned, almost all operations are forbidden.

To enable access to Yandex Data Streams resources (data streams, Yandex Managed Service for YDB databases storing the data streams, and database users), assign the required roles from the list below to a Yandex account, service account, federated users, user group, system group, or public group. Currently, a role can only be assigned for a parent resource (folder or cloud). Roles are inherited by nested resources.

Roles for a resource can be assigned by users who have the yds.admin role or one of the following roles for that resource:

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

Assigning rolesAssigning roles

To assign a user a role:

1. Add the required user if needed.
2. In the management console, on the left, select a cloud.
3. Go to the Access bindings tab.
4. Click Configure access.
5. In the window that opens, select User accounts.
6. Select a user from the list or search by user.
7. Click Add role and select a role for the cloud.
8. Click Save.

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.
