Collaborative theory-based DDoS (Distributed Denial of Service Attack) defense system and method

Abstract

The invention relates to a collaborative theory-based DDoS (Distributed Denial of Service Attack) defense system, which comprises a controller and cleaning equipment arranged on a switchboard, wherein the controller monitors a port of a full-network switchboard, and then pulls monitored network flow of an abnormal port of the switchboard to the cleaning equipment; the cleaning equipment is used for analyzing and cleaning the received network flow and supplying a security defense strategy to the controller based on an analysis result; and the controller configures the switchboard based on the security defense strategy, so as to relieve the attack.

Description

technical field [0001] The present invention relates to the field of network security, and more specifically, to a DDoS attack defense system and method based on synergy theory. Background technique [0002] With the rapid development and in-depth application of computer science and technology, changes in cyberspace are constantly changing and affecting people's way of life. As people rely more and more on the Internet, many confidential information about enterprises, individuals, and even countries are involved on the Internet, so the issue of network security has always been an important topic in the process of technological development. [0003] Among the many network attack methods existing on the Internet at present, Distributed Denial of Service Attack (Distributed Denial of Service Attack, DDoS for short) is the most common and highly destructive attack method. Most distributed denial-of-service attacks come from botnets, which cooperate with each other to launch den...

AI Technical Summary

Problems solved by technology

Since in the SDN network, all networks rely on a single controller, the controller can easily become the target of DDoS attacks, making this new type of network face new network security issues
