Permission Management

If you need to assign different permissions to employees in your enterprise to access your LakeFormation resources, IAM is a good choice for fine-grained permissions management. IAM provides identity authentication, permission management, and access control, helping you secure access to your Huawei Cloud resources.

With IAM, you can create IAM users for your employees, and assign permissions to these users to control their access to specific resource types. For example, if you want them to use LakeFormation but must not delete the databases or perform any high-risk operations, you can create IAM users and grant them only the permissions to query LakeFormation instances but not to delete them.

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

IAM is a free service. You only pay for the resources in your account. For more information about IAM, see What Is IAM?.

LakeFormation Service Permission

New IAM users do not have any permissions assigned by default. You need to first add them to one or more groups and attach policies or roles to these groups. The users then inherit permissions from the groups and can perform specified operations on cloud services based on the permissions they have been assigned.

LakeFormation permissions are assigned to users in the global project, and users do not need to switch regions when accessing OBS.

You can grant permissions by using roles and policies.

Roles: A coarse-grained authorization mechanism provided by IAM to define permissions based on job responsibilities. Only a limited number of service-level roles are available for authorization. If one role has a dependency role required for accessing SA, assign both roles to the users. Roles are not ideal for fine-grained authorization and least privilege access.
Policies: A fine-grained authorization mechanism 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 secure access control. For example, you can grant users only permission to manage cloud servers of a certain type.
