Permissions Management

If you want to assign different access permissions to employees in an enterprise for the DSC resources purchased on HUAWEI CLOUD, you can use Identity and Access Management (IAM) to perform refined permission management. IAM provides identity authentication, permissions management, and access control, helping you efficiently manage access to your DSC resources.

With IAM, you can create IAM users under your account for your employees, and assign permissions to these IAM users to control their access to DSC resources. For example, if you have software developers and you want to assign them the permission to access DSC but not to delete DSC or its resources, you can create an IAM policy to assign the developers the permission to access DSC but prevent them from deleting DSC data.

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

IAM is free. You pay only for the resources in your account. For more information about IAM, see IAM Service Overview.

DSC Permissions

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

DSC is a project-level service deployed and accessed in specific physical regions. To assign permissions to a user group, specify the scope as region-specific projects and select projects 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. To access DSC, the users need to switch to a region where they have been authorized to use cloud services.

You can grant users permissions by using roles and policies.

• Roles: A coarse-grained authorization mechanism provided by IAM to define permissions based on users' job responsibilities. This mechanism provides a limited number of service-level roles for authorization. You need to also assign other dependent roles for the permission control to take effect. Roles are not an ideal choice for fine-grained authorization and secure access control.
• Policies: A 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. For example, you can grant DSC users the permissions to manage only a certain type of resources.

Table 1 describes the system-defined policies of DSC.
