The method the synthesis of complexes of information security for support of conflictual and steady application of the executive elements of the social and economic organizations in the conditions of the competitive uncertainty caused by complete (partial) ignorance of strategy of behavior of competitors including physical and mathematical problem definition, methodical approaches to assessment of efficiency and a choice of their optimal variant is offered. The method is based on methods of theories of hierarchical multilayer systems, researches of operations, a maximin, the analysis and synthesis of difficult systems, methods of the maximum element and approximation by a polynomial not below the second level. The proposed method makes it possible to evaluate the effectiveness of the integral indicator and formulate sound proposals on rational variants of the composition of means and methods of using information security systems to ensure the use of executive elements of socio-economic organizations with maximum efficiency.
