A defense and network security device against distributed attacks based on big data

Abstract

The invention relates to a large data-based defense against distributed attacks and a network security device, including a network communication base station, a network switch, an Ethernet adapter, a cloud processor, a cloud database, an Ethernet interface, a wireless extender, and a network communication The base station, Ethernet interface, and wireless extender are included in the physical layer, and the network switch, Ethernet adapter, cloud processor, and cloud database are included in the data link layer. Devices and mobile devices signal IP in the network communication base station to search the processing history of the mobile device in the cloud database. The Ethernet adapter assigns any field to the distributed attack on the computer according to the processing history of the mobile device. The network switch converts the Ethernet The field assigned by the adapter is converted into the network signal received by the mobile device and transmitted to the mobile device, and the mobile device processes this part of the attack signal.

Description

technical field [0001] The invention relates to the field of network security, in particular to a big data-based defense against distributed attacks and a network security device. 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. 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 denial-of-...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem that the host computer under the same IP address can only adopt the defense against DDoS attack alone, and cannot make effective defense and counterattack to the attack in time under the attack of widely distributed DDoS like this, the present invention provides a method based on Big data defense against distributed attacks and network security devices
