The Design And Implemetion Of The Management System On Network Security Based On Stateful Detection Mechanism

With the prevalence and rapid development of network,how to manage the network effectively have become the key factor to make use of and protect net-resource not to be attacked and crabbed. Now ,there have been lots of system that have been able to manage some aspect of network well,however,there have been few management system that can regard all the security sub-system as a whole system.According to the status,the purpose of this paper is to analyze, design and implement the management system to administrate the net-security resource,from sub-component to GUI interface.We should pay more attention to study the technology about stateful detection and clarify how apply this type of technology in our task,meantime,we analyze the NAT technology and include it in our project.Except for the above key parts,on the basis of SNMP ,our project have also provided the statistic data collected from main nodes of school-network and created log files including the data used by other servers;by use of the modules and research methods about Agent technology in our NIC lab ,we could build tight link among the important servers in order to make these servers communicate effectively and provide valid data to the GUI interface,this type of mechanism could provide the administrator a way to fufill the real-time inspection on these nodes.This project have been implemented and applied in the real work enviroment.
