Permissions Management

Updated on 2024-05-09 GMT+08:00

If you need to assign different permissions to employees in your enterprise to access your resources, Identity and Access Management (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 OA resources but should not be allowed to perform any high-risk operations, such as deleting ECSs. In this scenario, you can create IAM users for the software developers and grant them only the permissions required for using OA resources.

If your Huawei Cloud account does not require individual IAM users for permissions management, skip 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?

OA Service Permissions

By default, new IAM users do not have any permissions assigned. You need to add the users to certain user groups and grant the user groups policies, so that the users in the groups can inherit the permissions.

  • Policies: A fine-grained authorization tool that defines permissions required to perform operations on specific cloud resources under certain conditions. This type of authorization is more flexible and is ideal for least privilege access. For example, you can grant ECS users only the permissions for managing a certain type of ECSs.

    Most fine-grained policies divide permissions by API.

As shown in Table 1, all system policies for OA are included.

OA CommonOperationsPolicy

Has the permissions to perform regular operations using OA, such as performing availability check. The cross-account availability check function is unavailable for users with this policy.

None

System-defined policies

OA ReadOnlyAccessPolicy

Has the read-only permissions for OA. Users that are assigned this policy can only view check results and resource groups, but cannot create or execute tasks.
