Problems solved by technology

At present, the protection ideas of terminal equipment still mainly follow the traditional Internet security thinking. The common practice is to directly transplant the authentication, firewall, anti-virus, data encryption and other technologies applicable to Internet terminals to IoT devices based on the hardware and software systems of IoT devices. In the networked terminal system, the technical ideas and protection methods are not designed according to the characteristics of the Internet of Things application, and cannot effectively solve the following security protection problems of the Internet of Things terminal equipment:
[0005] 1. A large number of terminal devices are exposed on the Internet, and the attack surface of the IoT system continues to expand;
[0006] 2. Terminal equipment manufacturers have different security backgrounds. The equipment itself may have built-in backdoors and loopholes. There is no standard reference for the security of products and their supply chains;
[0007] 3. Some devices lack security design and face new security risks in complex application environments. Once the IoT terminal device system is compromised, the entire protection system will fail

Embodiment 1

[0035] refer to figure 1 with figure 2 The present invention provides a method for network security protection of Internet of Things devices based on communication link monitoring. The method is based on a network communication link monitoring module 10, and the network communication link monitoring module 10 is connected in series to the network communication network of the Internet of Things terminal equipment. On the link, the function and control are independent of the hardware and software system of the IoT device itself, and the network communication link monitoring module 10 includes a network communication interface module A1, a terminal device communication interface module B2 and a data packet security monitoring module C3, The data packet security monitoring module C3 is responsible for judging and processing the legality of the data packet, the data packet security monitoring module C3 communicates with the network layer through the network communication interface...

Embodiment 2

[0039] refer to image 3, on the basis of Embodiment 1, the data packet security monitoring module C3 of the network communication link monitoring module 10 also includes a management submodule 31, and the management submodule 31 is communicatively connected with the data packet security monitoring module C3, so The management sub-module 31 has the function of setting and managing the processing rules in the data packet processing module, and the management sub-module 31 communicates with the remote security management platform 4 through the network communication interface module A1.

Embodiment 3

[0041] refer to Figure 4 , On the basis of Embodiment 2, the network communication link monitoring module 10 also includes a configuration pull-out switch module 32, and the configuration pull-out switch module 32 communicates with the data packet security monitoring module C3 and controls the data packet security The setting mode of the monitoring module C3, when the switches configured with the pull switch module 32 are in different switch positions, the setting modes of the safety monitoring module C3 are respectively not allowed to be set, only allowed to be set locally and allowed to be set remotely.

[0042] Further, the network communication link monitoring module 10 also includes a local configuration interface module 33, and the local configuration interface module 33 is communicatively connected with the security monitoring module C3, and can filter data packet rules, non-compliance data packet processing and The reporting rules are set locally, and the local config...

Abstract

The invention provides a method for performing network security protection on Internet of Things equipment based on communication link monitoring. The method is based on a network communication link monitoring module, wherein the network communication link monitoring module is connected to a network communication link of the Internet of Things terminal equipment in series; functions and control are independent of a software and hardware system of the Internet of Things device, the network communication link monitoring module is connected in series to a data link for communication between theInternet of Things terminal equipment and the network layer; all communication between the Internet of Things terminal equipment and the network layer needs to be carried out through the network communication link monitoring module, the data packet security monitoring module C carries out legality judgment and processing on passed data packets according to a built-in rule, the legal data packets can be transparently transmitted, and the illegal data packets are intercepted. The trust anchor is established on the network communication link of the Internet of Things terminal equipment, and the security protection mechanism is independent of the Internet of Things application, is not controlled by the Internet of Things application, and is high in universality and unique in security mechanism.
