This chapter describes how to use IAM to implement fine-grained permissions control for your DCS resources. With IAM, you can:
- Create IAM users for employees based on your enterprise's organizational structure. Each IAM user will have their own security credentials for accessing DCS resources.
- Grant only the permissions required for users to perform a specific task.
- Entrust an account or cloud service to perform efficient O&M on your DCS resources.
If your account does not need individual IAM users, you may skip over this chapter.
This section describes the procedure for granting the DCS ReadOnlyAccess permission (see Figure 1) as an example.
Prerequisites
You are familiar with the permissions (see Permissions Management) supported by DCS and choose policies or roles according to your requirements. For the permissions of other services, see Permissions Policies.
Process Flow
- Create a user group and grant permissions.
Create a user group on the IAM console, and attach the DCS ReadOnlyAccess policy to the group.
- Create an IAM user.
Create a user on the IAM console and add the user to the group created in 1.
- Log in and verify permissions.
Log in to the DCS console by using the newly created user, and verify that the user only has read permissions for DCS.
