Abstract


In the network , not just a few people 's entertainment pastime become the tools necessary to more people living and working today , along with the popularity of the Internet , there are various forms of cyber attacks and cyber crime , the life and work of the people caused by the extremely seriously affected. The popularity of the network so that more people access to the knowledge of the network , which also makes the means and methods of network attack and defense to become more diverse and more specialized . Off each scholar and network staff are committed to preventing and tracking malicious and non-malicious program error caused by cyber attacks and has made considerable progress . However , these methods are based on the mathematical model of the network itself , the paper uses Bayesian network to combine traditional network tracking mode of the LAN network attacks tracking and positioning , effective prevention due to the proliferation of removable storage devices and other internal LAN attack packets . The main contribution of this paper : traditional network attacks tracking method and mathematical statistical method using Bayesian network structure model to solve the idea the evidence missing the traditional attacks tracking method is easy to interrupt ; This article by a network of past attack record information fusion analysis of the potential law , each possible attack paths estimates of the degree of the threat , and the running do not need to consume network resources ; Bayesian network model of the application , and establish a global system of supervision , but also contribute to the day-to-day assessment and maintenance of the entire network 's ability to withstand attacks .
