Reactive Security for Multimedia Systems

This book proposes a new paradigm having the goal of whole system survivability against solutions that provide only individual components security. It introduces an adaptive framework where survivability can be effectively and efficiently provided to protect an entire system against intelligent malicious attacks and unpredictable misbehaviors. Such a new paradigm is necessary since over-reliance on single components protection solutions has actually contributed to the fragility of information systems when viewed as a whole. Increasing the survivability of information systems to underlying failures can be achieved by focusing on reducing the system vulnerabilities, while simultaneously increasing its restoration and adaptation capabilities. A survivable paradigm can, by means of an adequate reaction, fill the gap between theoretically secure controls and unavoidable implementation flaws. The book points out the errors and some of the wrong directions and approaches taken in the multimedia application market and proposes a technology that can satisfy theoretical and security requirements for video, audio and text content distribution.
