Permissions Management

If you want to assign different permissions to employees in your enterprise to access your CSBS resources purchased on HUAWEI CLOUD, IAM is a good choice for fine-grained permissions management. IAM provides identity authentication, permissions management, and access control, helping you secure access to your HUAWEI CLOUD resources.

With IAM, you can use your HUAWEI CLOUD account to create IAM users, and assign permissions to the users to control their access to specific resources. For example, some software developers in your enterprise need to use CSBS resources but must not delete them or perform any high-risk operations. To achieve this result, you can create IAM users for the software developers and grant them only the permissions required for using CSBS resources.

If your HUAWEI CLOUD account does not need individual IAM users for permissions management, skip this section.

IAM can be used free of charge. You pay only for the resources in your account. For more information about IAM, see IAM Service Overview.

CSBS Permissions

By default, new IAM users do not have permissions assigned. You need to add a user to one or more groups, and attach permissions policies or roles to these groups. Users inherit permissions from the groups to which they are added and can perform specified operations on cloud services based on the permissions.

CSBS is a project-level service deployed and accessed in specific physical regions. To assign CSBS permissions to a user group, specify the scope as region-specific projects and select projects (such as ap-southeast-2) for the permissions to take effect. If All projects is selected, the permissions will take effect for the user group in all region-specific projects. When accessing CSBS, the users need to switch to a region where they have been authorized to use this service.

Table 1 describes the system-defined role supported by CSBS. The role is dependent on other roles and needs to be used together with them to take effect.
