safety protection system for terminal equipment of Internet of Things

Abstract

The invention provides a safety protection system for the terminal equipment of an Internet of Things, which comprises an equipment discovery unit. The equipment discovery unit comprises a fingerprint code generation module, an equipment counterfeit monitoring module and an equipment recognition module; the network topology unit comprises a session tracking module, a flow analysis module, a topology management module and a switch drawing module; the service behavior management and control unit comprises a behavior modeling module, a credible range establishing module, a credible blocking module, an abnormal terminal isolation module and a service behavior checking module; and a safety protection unit. According to the method, network terminal discovery, safety access based on terminal fingerprints and terminal behavior safety protection are realized in a specific application environment, so that the defects of safety protection of massive Internet of Things terminals and safety early warning of network attacks in the specific environment can be overcome.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things security, and in particular relates to a safety protection system for Internet of Things terminal equipment. Background technique [0002] With the rapid development of the Internet of Things and the IP-based infrastructure communication system, the interconnection of massive devices through the network will become a trend, and today's society has gradually entered the era of the Internet of Things. Compared with the traditional Internet, the number of Internet of Things terminals is huge and the scope of physical deployment is wider. How to ensure the real-time visibility of the status of the Internet of Things and the controllability of the entire interconnection is a key issue in terms of security. In addition, a large number of front-end devices of the Internet of Things are scattered and unattended, and confidential data is easy to be stolen. Therefore, the establishment of visual ...

AI Technical Summary

Problems solved by technology

[0004] (1) There are many terminal devices in the Internet of Things, it is difficult to grasp the status of the devices, there is a risk of illegal access, and there is a lack of operation and maintenance methods, event monitoring and notification, and emergency response mechanisms;

[0005] (2) The terminal equipment of the Internet of Things is scattered and installed outdoors, and it is easy to be damaged by criminals due to improper management, resulting in physical attacks, tampering and counterfeiting;

[0006] (3) Internet of Things terminal devices generally have security risks such as weak passwords, loopholes, and a large number of open ports, and are easily infected by malicious codes to form zombie hosts, which in turn constitute botnets;

[0007] (4) The network protocols of IoT terminal equipment are diverse and have a large number of loopholes, which increases the channels for terminal infection of viruses, Trojan horses or malicious code intrusion, and increases the security risk of the network layer
