Research On Network Attack Detection And Self Defence In Enterprise Network

Through the analysis of MDCN (DCN network of china mobile) and it's defect on network access security, we introduction the solution of self defense platform on network access layer. Paper includes the following three aspects:analysis of network security on MDCN, research and design of self defense platform on network access layer, deployment of self defense platform software at MDCN.Firstly, we discuss normal network security problem and it's defense solution,then we introduce the network of MDCN, including it's topologic and service support, further, we analyze it's network security problem, focusing on network access layer security. On the base of above analysis,we develop one solution of self defense platform on network access layer, we introduce it's requirement analysis, architecture design, modular design, and also we research on several key and difficult technology. Finally, we introduce the application of self defense platform software at MDCN, focusing on it's deployment, configuration, and affection.
