System policies for Phone Number Verification Service

What is a system policy?

A policy defines a set of permissions that are described based on the policy structure and syntax. You can use policies to describe the authorized resource sets, authorized operation sets, and authorization conditions. RAM provides two types of policies: system policies and custom policies. All system policies are created and updated by Alibaba Cloud. You can use these policies but cannot modify them. You can manage and update custom policies based on your business requirements. You can create, update, and delete custom policies. During service iteration, Phone Number Verification Service adds new permissions to system policies to support new features and capabilities. The updates of system policies affect all RAM identities to which the policies are attached, such as RAM users, RAM user groups, and RAM roles. For more information about RAM policies, see Policy overview.

By default, a RAM identity has no permissions. The RAM identity can access resources within the Alibaba Cloud account only after the administrator of the Alibaba Cloud account grants the RAM identity the required permissions. To ensure resource security, we recommend that you follow the principle of least privilege to grant a RAM identity sufficient permissions to access Alibaba Cloud resources. For more information about how to grant the required permissions, see the following topics:

• Grant permissions to a RAM user

• Grant permissions to a RAM user group

• Grant permissions to a RAM role
