Network security monitoring system

Abstract

The invention relates to the technical field of the Internet, in particular to a network security monitoring system, which reduces the occupation of switch and server resources and improves the network security. Server maintenance personnel can conveniently and quickly discover DDoS attacks, so that the working efficiency is improved, and the use limitation is reduced. The system comprises a switch used for receiving a request message, checking a request message rule in the switch, sending a response message to a signal request source sending the request message after the request message passes, and sending a communication signal to a server after establishing a communication connection with the signal source; a receiving module used for receiving the request messages, obtaining the numberof the request messages in a preset time period of a user internally, and sending the request messages and a request message number signal; and an early warning module used for receiving the early warning signal and the request message sent by the judgment module, wherein when the early warning signal is not received, the early warning module does not work.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a network security monitoring system. Background technique [0002] As we all know, the network security monitoring system is a system used to ensure network security, which has been widely used in the field of the Internet; the existing network security monitoring system includes a switch, which is used to receive request messages, and Check the request message rules, after the request message is passed, send a response message to the signal request source that sent the request message, and send a communication signal to the server after establishing a communication connection with the signal source; the server is used to receive the communication signal and Communicate with the signal request source through the switch; when the existing network security monitoring system is used, the signal request source sends a request message to the switch, and the switch receives the r...

[0002] As we all know, the network security monitoring system is a system used to ensure network security, which has been widely used in the field of the Internet; the existing network security monitoring system includes a switch, which is used to receive request messages, and Check the request message rules, after the request message is passed, send a response message to the signal request source that sent the request message, and send a communication signal to the server after establishing a communication connection with the signal source; the server is used to receive the communication signal and Communicate with the signal request source through the switch; when the existing network security monitoring system is used, the signal request source sends a request message to the switch, and the switch receives the request message and checks the request message rules inside the switch. After the request message passes, Send a response message to the signal request source that sent the request message, and send a communication signal to the server after establishing a communication connection with the signal source, and then the server receives the communication signal and communicates with the signal request source through the switch; the existing network security monitoring system During use, it was discovered that Distributed Denial of Service (Distributed Denial of Service, DDoS) is: using distributed signal request sources to send a large number of requests to the server, consuming or occupying switch and server resources for a long time, so that the server cannot provide services normally, causing network Poor security; and after the server is attacked by DDoS, it is difficult for the server maintenance personnel to quickly find out, resulting in low work efficiency and high usage limitations
