Description: The article is related to the issue of resource management of the software information security complex in dynamic information confrontation. An analysis of the current state of the information security systems development showed the existence of contradictions between the variety of software information security nomenclature with different technical and economic characteristics and an optimal sets of constructing options for software information security complexes. Despite the presence of wellknown methods for analyzing the effectiveness of information security investments, in most organizations decisions in the field of information security are usually taken spontaneously, at best, based on expert judgment. In this regard, the real costs in one case may be too high, in the other – insufficient. In order to solve these contradictions, it is proposed the formalized statement of resource optimization problem for software information security complex. Effectiveness of the targeted use of software information security complex (preserving, increasing or providing a minimum reduction in the efficiency of application in time) requires some adaptation changes, both in the main components of the complex and the structure of the complex as a whole, in response to dynamic changes in information confrontation. The adaptation mechanism (resource optimization) of software information security complex in dynamic information confrontation proposed in the form of functional-dynamic model. It shows that the fuzzy approach allows to optimize the indicators of software information security complex due to the rational choice of membership functions, which reflect the main characteristics of objects – the reaction of the complex to a combination of factors affecting it and the available resources of the system. The article proposes formalization and formulation of the resource optimization problem for software information security complex in dynamic information confrontation using the theory of adaptive control and logical-dynamic systems. Proposed approach allows to assess the level of influence of environmental factors on the efficiency level of software information security complex when activating and using its various internal resources.
