A Zombie Network Topological Analysis And Counter-algorithm Research

Botnet is a novel attack strategy evolved from traditional malware forms;it provides the attackers stealthy,flexible and efficient one-to-many Command and Control mechanisms,which can be used to order an army of zombies to achieve the goals including information theft,launching distributed denial of service,and sending spam. Botnet has stepped into the expanding phase,and has been a serious threat to Internet security,especially in China mainland. In this thesis,the evolution process, concept,functional structure and execution mechanism of Botnet are presented,the Command and Control mechanisms and propagation model are discussed,and advance two methods of control Botnet.the latest techniques on Botnet tracking,detection and prevention are reviewed. The developing trends of Botnet and further topics in this area are also analyzed.We opposes two kinds Botnet that the network analyses owing to society brought forward by the main body of a book making an algorithm, key node and bridge node in the network making use of them to be able to discover a corpse comparatively accurately links up, and by being able to slow down a corpse effectively to key node treatment, network propagation rate;Pass the supervisory control to the bridge node and key interlinkage and hinder breaking, can the network topology structure destroying a corpse with minimal price , the network propagation controlling a corpse effectively.
