This book brings to light the concept of digital Immunity and how it can be applied to combat cybercrime and terrorism. The Cognitive Early Warning Predictive System (CEWPS) is in fact the new Digital Immune System. The book describes the landscape of cyber warfare, vulnerability of the critical infrastructures, shortcomings of AVT, the human immune system, and then it zooms on the architecture and the technologies of CEWPS. A big portion of the book, which is the best part of the book, includes vivid attack scenarios on some major infrastructures and how CEWPS deter and annihilate the attack.
