Intelligent network intrusion detection system of hardware protocol

Abstract

The invention discloses an intelligent network intrusion detection system of a hardware protocol, which comprises an IP packet capturing module, a network data feature extraction module and a decision classification module, and is characterized in that the IP packet capturing module is arranged at a PS end of a ZYNQ platform, is connected with an industrial control network and is used for capturing an IP packet of the industrial control network; the network data feature extraction module is arranged at the PS end of the ZYNQ platform, is connected with the IP packet capture module and is used for extracting network data features in the IP packet; and the decision classification module is arranged at the PL end of the ZYNQ platform, adopts an FPGA chip, is connected with the network data feature extraction module, and is used for carrying out network behavior identification and classification on the network data features and intercepting dangerous data. According to the system, IP packet capture and network data feature extraction of a PS end and a hardware classification algorithm of a PL end are realized based on a ZYNQ platform, and meanwhile, PS and PL are organically combined, so that decision classification of network data is realized to perform network intrusion detection.

Description

technical field [0001] The invention relates to the technical field of network information security transmission and intrusion detection, in particular to an intelligent network intrusion detection system with hardware protocols. Background technique [0002] In recent years, countries around the world have set off the fourth industrial revolution represented by the Industrial Internet of Things. Smart factories and "intelligent manufacturing" of products have attracted widespread attention. The Industrial Internet of Things has shown people a beautiful picture and demonstrated A broad market development prospect. Industrial Internet of Things is a new concept, which is the product of the combination of traditional industrial automation and industrial informatization to a certain stage. The Industrial Internet of Things breaks through the limitations of traditional local area networks, and combines factory production, enterprise management, and marketing. The potential of ...
