Internet worm attacks have become increasingly more frequent and have had a major impact on the economy, making the detection and prevention of these attacks a top security concern. Several counter-measures have been proposed and evaluated in recent literature. However, the effect of these proposed defensive mechanisms on legitimate competing traffic has not been analyzed. This book presents a comparative analysis of the effectiveness of several of these proposed mechanisms, including a measure of their effect on normal web browsing activities. This book also presents a study of the behavior of TCP based worms in MANETs. We develop an analytical model for the worm spread of TCP worms in the MANETs environment that accounts for payload-size, bandwidth-sharing, radio range, nodal density and several other parameters speci¬c for MANET topologies. We also present numerical solutions for the model and verify the results using packet-level simulations. The results show that the analytical model developed here matches the results of the packet-level simulation in most cases.

Through his years of intensive work consulting to companies including Procter & Gamble, Sony, Toyota, Microsoft, Ford and Ernst & Young, with his firm The Energy Project, Schwartz has developed a powerful program for changing the way we are working that greatly boosts our engagement and our satisfication with our work and increases our performance. In this book he marshalls a wide range of powerful evidence from business research and psychology that shows that the current model of work -- in which people are treated essentially as machines that should be able to perform at top speed for extraordinarily long hours, be Modeling and Simulation of Worms and Mitigation Techniques free download pdf able to multi-task, be always accessible and online, withstand often harsh and emotionally punishing treatment, and be primarily driven by the need to make profits -- is not only not optimal, it is specfically counter-productive because it saps us of our physical, emotional, mental and spiritual energy.
