Permissions Management

If you need to assign different permissions to employees in your enterprise to access your DBSS 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 cloud resources.

With IAM, you can use your account to create IAM users for your employees, and assign permissions to the users to control their access to specific resource types. For example, some software developers in your enterprise need to use DBSS but must not delete DBSS resources 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 DBSS resources.

If your account does not need individual IAM users for permissions management, then you may skip over this chapter.

DBSS 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. After authorization, the user can perform specified operations on BMS based on the permissions.

DBSS is a project-level service deployed and accessed in specific physical regions. To assign DBSS 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 DBSS, the users need to switch to a region where they have been authorized to use cloud services.

DBSS roles are dependent on the roles of other services. When assigning DBSS permissions to users, you need to also assign dependent roles for the DBSS permissions to take effect.

**Table 1** System roles supported by DBSS
Role Name	Description	Dependency

VPC Administrator: Users with this set of permissions can perform all execution permission for Virtual Private Cloud (VPC). It is a project-level role, which must be assigned in the same project. BSS Administrator: Users with this set of permissions can perform any operation on menu items on pages My Account, Billing Center, and Resource Center. It is a project-level role, which must be assigned in the same project. ECS Administrator: Users with this set of permissions can perform any operations on an ECS. It is a project-level role, which must be assigned in the same project.
