Simple Message Queue (formerly MNS):Authorize a RAM user

Scenarios

Enterprise A purchases the SMQ service. The employees of Enterprise A need to manage SMQ resources, such as queues and topics. Employees with different roles require different permissions.

The following section describes specific scenarios:

• For security reasons, Enterprise A does not want to disclose the AccessKey pair of its Alibaba Cloud account to employees. Instead, Enterprise A wants to create different RAM users for the employees and grant different permissions to the RAM users.

• A RAM user can only use resources for which the user is authorized. Resource usage and costs are not separately calculated for the RAM user. All expenses are billed to the Alibaba Cloud account of Enterprise A.

• Enterprise A can revoke the permissions granted to a RAM user and delete a RAM user at any time.

In this scenario, the Alibaba Cloud account of Enterprise A can grant its employees fine-grained permissions on resources.

Method 1: Grant permissions to a RAM user on the Users page

1. Log on to the RAM console as a RAM administrator.

2. In the left-side navigation pane, choose Identities > Users.

3. On the Users page, find the required RAM user, and click Add Permissions in the Actions column.

   

   You can also select multiple RAM users and click Add Permissions in the lower part of the page to grant permissions to the RAM users at a time.

4. In the Grant Permission panel, grant permissions to the RAM user.

   1. Configure the Resource Scope parameter.

      • Account: The authorization takes effect on the current Alibaba Cloud account.

      • ResourceGroup: The authorization takes effect on a specific resource group.

        Important

        If you select Resource Group for the Resource Scope parameter, make sure that the required cloud service supports resource groups. For more information, see Services that work with Resource Group. For more information about how to grant permissions on a resource group, see Use a resource group to grant a RAM user the permissions to manage a specific ECS instance.

   2. Configure the Principal parameter.

      The principal is the RAM user to which you want to grant permissions. The current RAM user is automatically selected.

   3. Configure the Policy parameter.

      A policy contains a set of permissions. Policies can be classified into system policies and custom policies. You can select multiple policies at a time.

      • System policies: policies that are created by Alibaba Cloud. You can use but cannot modify these policies. Version updates of the policies are maintained by Alibaba Cloud. For more information, see Services that work with RAM.

        Note

        The system automatically identifies high-risk system policies, such as AdministratorAccess and AliyunRAMFullAccess. We recommend that you do not grant unnecessary permissions by attaching high-risk policies.

      • Custom policies: You can manage and update custom policies based on your business requirements. You can create, update, and delete custom policies. For more information, see Create a custom policy.

   4. Click Grant permissions.

5. Click Close.
