Security issues have become a major issue in recent years due to the development of technology in networking and its use in vicious way. A number of puzzle-based defense strategies have been established to overcome the flooding Denial-of-Service (DoS) attack which is eminent in the networks. DoS attacks are aimed at the loss of or the exhaustion in availability, which is one of the most important general security obligations in computer networks. But these strategies are not designed in an optimally and effectively and some of the important issues have been undetermined. This paper contributes detailed analysis of game theory based approach to create a series of defense strategies using puzzles for handling increasing convoluted flooding attacks.
