Access management in Managed Service for YDB

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 YDB resources (databases and their users), assign the required roles from the list below to a Yandex account, service account, federated users, user group, system group, or public group. A role can be assigned for a parent resource (folder or cloud) whose roles are inherited by nested resources.

You can also grant a role to access a specific database. This will allow a user without any roles in the directory hosting the database to access the database according to the role assigned.

Roles for a resource can be assigned by users who have the ydb.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

3. Go to the Access bindings tab.
4. Click Configure access.

7. Click Add role and select a role for the cloud.
8. Click Save.

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

You can assign a role to an organization, cloud, or folder. The roles assigned for organizations, clouds, or folders also apply to nested resources.

You can also assign a role for individual resources of the service. The list of such resources depends on the Yandex Cloud interfaces you use to assign roles:

• In the management console, you can only assign roles for a YDB DBMS.
• Via the YC CLI or Yandex Cloud API, you can assign roles for a DBMS and its backup.

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.
