Research On The Design And Implementation For Simulation Platform Of Network Attacking & Defense And Firewall

The development of network requires more deliberate researches on network security technologies (including network attacking technology and network defense technology). The principles and some familiar open source tools of network security technologies are summarized, based on which a platform of network attacking & defense and its architecture are presented and a virtual network environment is also implemented. The principle and technology of the virtual firewall of the architecture and the usage of the platform of network attacking & defense are explained in detail, including the constitution and the parsing of the firewall rules, the security strategies and the detecting process of the firewall, the generation of the network data flow, the establishment of the network topology, the usage of every network device and so on.The presentation and the implementation of the platform of network attacking & defense enable the two aspects of the research of network security technologies, that is the research of network attacking technology and the research of network defense technology, to be combined in an identical environment and make the research of the principle of network attacking & defense more intuitionistic. This paper's work is of great importance in both the research and the teaching of network security.
