Applying an MFA policy to users

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id options.

1. View a list of users or groups subject to the MFA policy:

   yc organization-manager mfa-enforcement list-audience \
     --id <policy_ID>
   

2. See the description of the CLI command for changing the list of users or groups subject to the MFA policy:

   yc organization-manager mfa-enforcement update-audience --help
   

3. To add users or groups to the MFA policy, or to remove them from it, run this command:

   yc organization-manager mfa-enforcement update-audience \
     --id <policy_ID> \
     --audience-delta subject-id=<subject_ID>,action=<action>
   

   Where:

   • --audience-delta: Parameter to edit the list of users/groups in the policy:
     • subject-id: User or group ID.
     • action: Action, action-add to add, action-remove to delete.

   You can specify multiple --audience-delta parameters to edit more than one object at the same time.

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the relevant documentation on the Terraform website or its mirror.

If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

1. To add a user or group to an MFA policy, describe the yandex_organizationmanager_mfa_enforcement_audience resource parameters in the configuration file:

   resource "yandex_organizationmanager_mfa_enforcement_audience" "example_mfa_audience" {
     mfa_enforcement_id = "<MFA_policy_ID>"
     subject_id         = "<user_or_group_ID>"
   }
   

   Where:

   • mfa_enforcement_id: ID of the MFA policy to which you want to add a user or group. This is a required parameter.
   • subject-id: ID of the user or group you need to add to the MFA policy. This is a required parameter.

   To add multiple users or groups, create a separate yandex_organizationmanager_mfa_enforcement_audience resource for each one.

   For more information about yandex_organizationmanager_mfa_enforcement_audience properties, see this provider guide.

2. Create the resources:

   1. In the terminal, go to the directory where you edited the configuration file.

   2. Make sure the configuration file is correct using this command:

      terraform validate
      

      If the configuration is correct, you will get this message:

      Success! The configuration is valid.
      

   3. Run this command:

      terraform plan
      

      You will see a detailed list of resources. No changes will be made at this step. If the configuration contains any errors, Terraform will show them.

   4. Apply the changes:

      terraform apply
      

   5. Type yes and press Enter to confirm the changes.

   Terraform will create all the required resources. You can make sure the users were added to the MFA policy using the Cloud Center UI or this CLI command:

   yc organization-manager mfa-enforcement list-audience --id <policy_ID>
   

3. To delete a user or group from an MFA policy, delete the relevant yandex_organizationmanager_mfa_enforcement_audience resource from the configuration file and apply the changes.

Use the UpdateAudience REST API method for the MfaEnforcement resource or the MfaEnforcementService/UpdateAudience gRPC API call.
