Botnet: Classification, Attacks, Detection, Tracing, and Preventive Measures

Free registration required

Executive Summary

Botnets become widespread in wired and wireless networks, whereas the relevant research is still in the initial stage. In this paper, a survey of botnets is provided. The authors first discuss fundamental concepts of botnets, including formation and exploitation, lifecycle, and two major kinds of topologies. Several related attacks, detection, tracing, and countermeasures, are then introduced, followed by recent research work and possible future challenges. The untraceable feature of coordinated attacks is just what hackers/attackers demand to compromise a computer or a network for their illegal activities. Once a group of hosts at different locations controlled by a malicious individual or organization to initiate an attack, one can hardly trace back to the origin due to the complexity of the Internet.
