The information stage of human society development which began at the end of the last century results in the fact that the state of information security has become directly dependent not only on the information processing technical systems and features but also on the perception of information at the level of individual psychological qualities. The use of information aggression and special information operations including those performed in modern geopolitics at the international and domestic levels for population management, during electoral campaigns is gaining enormous scope. The tasks of early information impact detection, situation development modeling in the information space necessitate the development of specialized models reproducing information confrontation. The major contradiction in the development of such models is that the more relevant and adaptive these models are the more complex and resource-intensive they become. At the same time, oversimplifying the information confrontation process makes such models inconsistent with real risks. This article gives a brief overview of modern information confrontation models and concepts. It is described the basic principles of the construction of an information confrontation ontological model: such key elements as subjects, objects, actual impacts, and the basic characteristics of each element are identified. An attempt has been made to develop a universal information confrontation ontological model. It has been also proposed a multipart tuple of information confrontation representation. This article is the beginning of a separate research project on information confrontation modeling, which will be further developed in papers to follow.
