Traditional fortress mentality of system security has proven ineffective to attacks by disturbing technology. They allow the system to adapt to incoming threats, removing many of the vulnerabilities exploited by viruses and worms. Disruptive Security Technologies With Mobile Code and Peer-To-Peer Networks provides the foundation for developing these adaptive systems by explaining the design principles and fundamentals of the new security paradigm embracing the technology disruptive. In order to provide a thorough grounding, the author covers such topics as mobile code, strong peer-to-peer networks, multi-fractal model of network flow, security automata, reliability, service quality, mobile code paradigms, code confusion, and distributed adaptation techniques as part of the security system. adaptive network system allows designers to get parallel to the attacker.
