Permission Management

Updated on 2024-11-08 GMT+08:00

If you need to assign different permissions to employees in your enterprise to access your UGO resources, IAM is a good choice for fine-grained permissions management. IAM provides identity authentication, permissions management, and access control, helping you securely manage 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, you can grant software developers in your enterprise permissions to use UGO resources but not permissions needed to 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 UGO resources.

If your Huawei Cloud account does not need individual IAM users for permissions management, you may skip over this section.

IAM can be used for free. You pay only for the resources in your account. For more information about IAM, see What Is IAM?

UGO Permissions

By default, new IAM users do not have any 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 they belong to and can perform specified operations on cloud services based on those permissions.

UGO is a project-level service deployed in specific physical regions. To assign UGO permissions to a user group, select a project (ap-southeast-3) in a specific region (AP-Singapore) to apply the permission changes. If all projects are selected, the permissions will take effect for the user group in all region-specific projects. When accessing UGO, you need to switch to a region where you have been authorized to use this service.

You can grant users permissions by using roles and policies.

  • Roles: A type of coarse-grained authorization mechanism that defines permissions related to users responsibilities. This mechanism provides only a limited number of service-level roles for authorization. There may be dependencies involved between different roles. If these dependencies are not taken into account, you may be unable to properly assign the permissions as intended. Roles are not ideal for fine-grained authorization and secure access control.
  • Policies: A type of fine-grained authorization mechanism that defines permissions required to perform operations on specific cloud resources under certain conditions. This mechanism allows for more flexible policy-based authorization, meeting requirements for secure access control.

Table 1 and Table 2 illustrate all the built-in roles and policies of the UGO.
