Disclosed are a method for controlling a terminal to access a network, and a device, a system, an apparatus and a storage medium. In the embodiments of the present application, information of an IoT terminal indicated by an industrial Internet identifier of the IoT terminal is relatively accurate, and therefore, a network access policy of the IoT terminal that is determined on the basis of the information of the IoT terminal indicated by the industrial Internet identifier of the IoT terminal is also relatively accurate. On this basis, network access of the terminal is controlled on the basis of the network access policy, such that a network security risk brought about by the IoT terminal accessing the network can be reduced, thereby improving the security of the network access of the IoT terminal.
