Method and system for enhancing network attack prevention capability of multiple network ports

Abstract

The invention discloses a method and a system for enhancing the network attack prevention capability of multiple network ports. The method comprises the following steps that: S1, all line protection devices adopt FPGA-based network ports; S2, each line protection device independently receives different attacks of the simulation attack management system, training is carried out according to the attacks, and an FPGA network port is reconstructed during training; S3, the trained line protection device forms an FPGA network port with the function of filtering the attack; S4, each line protection device uploads the FPGA network port model formed after S3 to a system control center; and S5, the system control center synthesizes the models of the FPGA network ports uploaded by all the line protection devices and then issues the synthesized models to all the line protection devices. According to the reconfigurable multi-network-port anti-network-attack and enhancement mechanism based on the FPGA, each single network port can share attack information with other network ports to enhance the self anti-attack capability, and the FPGA-based network port anti-network-attack capability of each device becomes more and more powerful and complete as time goes on.
