The Design And Implemention Of Network Attack Defent Platform Base On VirtualBox

With the development of the Internet, more and more attention has been paid to the security of information network. How to design a secure network? What is unsafe network? How to judge a network as safe or not? What are the common means of attack? How to prevent? All we need to think deeply.The paper develops the built-in network function, constructs attack host and attacked host platform based on virtualization software of Virtual Box. Besides, it simulates real network switches and routers using GNS3 and IOU(Web IOU) and simulates real network firewall with Hi-Spider open source firewall system. Furthermore, it simulates real network intrusion detection system by easyspy, so as to design and construct a virtual real network. In this virtual network, security penetration tool of Kali Linux was used to process experiment or demonstration of network attack and defense penetration, which reflects the whole process of the platform.This system intends to design and realize the virtual laboratory which enables network administrators, information security administrator or users who are interested in network security to conduct various network experiments, network attack and defense experiments, in order to improve the understanding of network security as well as the defense capability of the network. Thus, it is of great popularizing significance in work, scientific research and teaching.
