Permissions Management

Updated on 2023-08-03 GMT+08:00

If you need to assign different permissions to different employees in your enterprise to access your VOD resources, 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 VOD but are not allowed to delete VOD resources or perform any high-risk operations. To this end, you can create IAM users for the software developers and assign them only the permissions for using VOD.

If your Huawei Cloud account does not require 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.

VOD 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.

VOD is a project-level service deployed in different 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. When accessing VOD, the users need to switch to a region where they have been authorized to use VOD.

You can grant users permissions by using roles and policies.

  • Roles: A type of coarse-grained authorization mechanism that defines permissions related to user responsibilities. This mechanism provides only a limited number of service-level roles for authorization. If one role has a dependency role required for accessing VOD, assign both roles to the users. However, roles are not an ideal choice 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. For example, you can grant VOD users only the permissions for managing a certain type of cloud resources.

Table 1 lists all the system-defined roles and policies supported by VOD.
