Access management in Identity and Access Management

In this section, you will learn about:

• Resources you can assign a role for.
• Roles this service has.
• Roles are required for specific actions.

Access managementAccess management

Yandex Identity and Access Management checks all operations in Yandex Cloud. If an entity does not have required permissions, IAM returns an error.

To grant permissions for a resource, assign the relevant resource roles to an entity performing operations. You can assign roles to a Yandex account, service account, local user, federated user, user group, system group, or public group. For more information, see How access management works in Yandex Cloud.

To assign a role for a resource, a user should have the iam.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

Resources you can assign a role forResources you can assign a role for

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

You can assign a role for a service account in the management console or using the Yandex Cloud CLI, API, or Terraform.

Roles this service hasRoles this service has

The chart below shows service’s roles and their permission inheritance. For example, editor inherits all viewer permissions. You can find role descriptions below the chart.

Service rolesService roles

iam.serviceAccounts.useriam.serviceAccounts.user

The iam.serviceAccounts.user role enables viewing the list of service accounts and info on them, as well as performing operations on behalf of a service account.

For example, if you specify a service account when creating an instance group, IAM will check whether you have a permission to use this service account.

iam.serviceAccounts.adminiam.serviceAccounts.admin

The iam.serviceAccounts.admin role enables managing service accounts and access to them and their keys, as well as getting IAM tokens for service accounts.

Users with this role can:

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 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 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 includes the editor permissions.

Instead of primitive roles, we recommend using service roles with more granular access control, allowing you to implement the least privilege principle.

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