Research And Application Of Network Security Monitoring System

As the trend of global informationization, represented by Internet, is increasingly obvious, the information network technology application is more and more general and popular in bank, securities company, and other financial services enterprise. But along with the continuous development of the application, the network security risk also be exposed unceasingly. Therefore the network security plan solution for financial field is not allowed to neglect any longer.This paper first introduces the background and nowaday studies about the network security supervisory system, then introduces and contrasts the good and bad points of several typical network security technologies, such as the firewall technology, the invasion examination technology, the VPN technology, the authentication technology and so on. Second, this paper analyses various security hidden dangers as well as the advantages and disadvantages of different attacks, and proposed a network security monitoring method and the realization. Take account of tradition network firewall, the invasion examination and the C/S pattern hacker supervisory system merit, this network security supervisory system adopts the multi-layered distriutional C/S architecture. Then this paper describes the essential subsystem and other essential subsystem design and the realization detailedly. Finally, this paper gives the system test result, which indicates that the system has meat the function and performance requirement, achieved the design purpose about the function, the performance and the stability, and could be applied in the actual environment for use.
