Understanding Botnet: From Mathematical Modelling to Integrated Detection and Mitigation Framework

No one is absolutely sure about cyber security as long as a communication system is connected to the internet, since internet is a wild that comprises all kind of people around the world from white hat to black hat. In other words, virtually any Internet connected system is vulnerable to major outrages from receiving a spam email to a botnet originated DDOS attack. But every individual, company and government wants to make sure that the security of their system is dependable so that they can use the outmost benefits of the twenty first century information society advantage. Since the problem is inevitable it very critical to understand the properties of this nefarious attacking machines from different perspective. In this paper we have developed a mathematical model to scrutinize the favouring and hindering factors for botnet propagation and growth. In addition we have proposed a detection and mitigation framework based on the model we developed.
