Infrastructure Security, A Total Defense Strategy: By Active/Passive Attribute Analysis & Mediating Technology Synthesis

Engineering efforts are oriented towards pre-designated goals. The management of any effort needs planning. Plans that do not account for uncertainty are inefficient. In efficient plans, assumptions should be reduced to the most and should corporate security. The aim of security is to guarantee the achievement of ultimate goals by reduction of assumptions and uncertainty. This study presents a mathematical analysis of security. A security model is constructed to deal with any system. Also, algorithms are developed to enhance security of systems. This study aims at integrating security in engineering and management. Based on the definition of a general system, a model for security and system analysis is suggested. The model uses the concept of clustered graph to reflect the systems' structure and dynamics. Then, the dynamics and security policies are formulated and analyzed. The impact of systems growth known as composition is studied and analyzed. Similarly the impact of system decomposition on security is analyzed. Based on the analysis of impact, an algorithm is developed to split a system to enhance security. The enforcement of security policies to a given system is studied based on the model. An algorithm to optimize using mechanisms is also developed.
