State firewall state detection system and method based on industrial Internet of Things

Abstract

The invention discloses a state firewall state detection system and a method based on the industrial Internet of Things. The system comprises an application layer drive unit used for driving user side application layer programs and/or files, a sensing layer drive unit used for driving information interaction ports, a network state detection unit used for detecting and processing the network state of the industrial Internet of Things, and a network management database used for serving the network state detection unit and matched therewith and a network layer drive unit, wherein the application layer drive unit, the network state detection unit and the sensing layer drive unit are in communication connection in sequence. The state firewall state detection system and the method based on the industrial Internet of Things in the invention can overcome the defects of weak protocol stack architecture support force, slow detection speed, and poor flexibility in the prior art, so as to realize the advantages of strong protocol stack architecture support force, fast detection speed and good flexibility.

Description

technical field [0001] The present invention relates to the technical field of network boundary protection equipment, in particular to a stateful firewall state detection system and method based on the Industrial Internet of Things. Background technique [0002] Modern industrial technology has four characteristics: networked structure, decentralized control, intelligent power saving and system integration, that is, the Industrial Internet of Things from the on-site equipment layer and control layer to the scheduling management layer and business management layer. The Industrial Internet of Things refers to the integration of heterogeneous networks such as the Internet, WSN, and fieldbus networks on the basis of traditional industrial networks, and the continuous integration of various terminals with environmental awareness, cloud computing models, mobile communications, and real-time communications into industrial production. all aspects of the network. In short, the Indus...

Problems solved by technology

[0014] There are deficiencies in the above two schemes: the disadvantage of the first scheme is that it lacks certain flexibility, because it needs to check the rules for each data packet passing through it, and in the case of a large number of filtering rule tables , will lead to a sharp drop in system performance

The state detection mechanism of the second scheme is limited to the underlying TCPIP protocol of the Industrial Internet of Things, and has no protective effect on other underlying heterogeneous protocols, etc.

[0015] In the process of realizing the present invention, the inventor found that there are at least defects in the prior art such as poor support for the protocol stack architecture, slow detection speed and poor flexibility.
