Creating a User and Granting IoTDA Permissions

You can use Identity and Access Management (IAM) for fine-grained permissions control for your IoTDA resources. With IAM, you can:

Create IAM users for personnel based on your enterprise's organizational structure. Each IAM user has their own identity credentials for accessing IoTDA resources.
Grant users only the permissions required to perform a given task based on their job responsibilities.
Entrust a Huawei Cloud account or a cloud service to perform efficient O&M on your IoTDA resources.

If your Huawei Cloud account does not need individual IAM users, then you may skip this section.

This section describes the procedure for granting permissions. Figure 1 shows the process flow.

Prerequisites

Before granting permissions to user groups, learn about system-defined permissions supported by IoTDA. To grant permissions for other services, learn about all system-defined permissions supported by IAM.

Process Flow

Figure 1 Process of granting IoTDA permissions

Create a user group and grant it permissions: Create a user group on the IAM console and assign the IoTDA ReadOnlyAccess permissions to the group.
Create a user and add it to the user group: Create a user on the IAM console and add the user to the user group created in 1.
Log in as the IAM user and verify permissions: In the authorized region, perform the following operations:
- Choose Service List > IoT Device Access. Then register a device on the IoTDA console. If a message appears indicating that you have insufficient permissions to perform the operation, the IoTDA ReadOnlyAccess policy is in effect.
- Choose another service from Service List. If a message appears indicating that you have insufficient permissions to access the service, the IoTDA ReadOnlyAccess policy is in effect.
