Creating a User and Granting Permissions

This section describes IAM's fine-grained permissions management for your HSS resources. With IAM, you can:

Create IAM users for employees based on the organizational structure of your enterprise. Each IAM user has their own security credentials, providing access to HSS resources.
Grant only the permissions required for users to perform a specific task.
Entrust a cloud account or cloud service to perform professional and efficient O&M on your HSS resources.

If your account does not require individual IAM users, skip this chapter.

This section describes the procedure for granting permissions (see Figure 1).

Prerequisite

Before authorizing permissions to a user group, you need to know which HSS permissions can be added to the user group. Table 1 describes the policy details.

**Table 1** System-defined permissions supported by HSS
Role/Policy Name	Description	Type	Dependency
HSS Administrator	administrator, who has all permissions of	System-defined role	It depends on the Tenant Guest role. Tenant Guest: A global role, which must be assigned in the global project.
HSS FullAccess	All permissions	System-defined policy	None
HSS ReadOnlyAccess	Read-only permission for	System-defined policy	None

Authorization Process

Figure 1 Process for granting permissions

Create a user group and assign permissions. On the IAM console, grant the HSS Administrator permission.
Create a user and add it to the group. On the IAM console, add the user to the group created in 1.
Log in and verify permissions.
Log in to the HSS console as the created user, and verify that the user only has read permissions for HSS.

In Service List on the console, select any other services (for example, there is only the HSS Administrator policy). If a message indicating that the permission is insufficient is displayed, the HSS Administrator permission takes effect.
