Security Framework Based On Multiple Layers Of Defense And Implementation Of Network Management System

Firstly this paper analyses the current Security Managements' of Network Management System problems and disadvantages, and it points out that their accuracy is very low mainly because of they detecting intrusions by only one characteristic of intrusions without considering the intrusions' effects.To solving other security productions' disadvantages, this paper divides the network facility into five levels using artificial immune system's multilayer defence mechanism and fuzzy recognition, such as hardware performance, network data, system processes, system data and application service etc. And this method sets many detective parameters on each level. So using these parameters the method can detect the network's security status and intrusions to protect the whole network.This method not only considers the intrusions' characteristics but also their effects, so it improves the accuracy of detective. And the paper also represents the detailed prototype implementation of Multi-hierarchy based security frame. At last, the paper concludes that the prototype can improve the accuracy of Security Management of Network Management System.
