The need to develop a wider range of methods and tools for system analysis and modeling, allowing to develop and implement anti-terrorism measures, was noted. The results of a model analysis of terrorist activity in media space are presented. The research is based on already approved model solutions. It is proposed to use the combination and integration of humanitarian knowledge and natural science tools. A cognitive analysis of the communication model of a successful terrorist attack and models of proactive counteraction to terrorist threats was carried out. Models are single- or multi-loop schemes with positive or multidirectional feedbacks. Functional-structural models for countering the coverage of terrorist activities in media space have been constructed. The context of the model of counteraction to terrorist threats is defined. Based on the hierarchical decomposition of the diagrams, the features of the structural organization of the counteraction process are investigated. The proposed model approach allowed to build a study, starting from the description of generalized structures to the analysis of the functioning of the system of counteracting the coverage of terrorists in the media space. The obtained models illustrate the mechanisms of formation of a system of links between state and public institutions targeted to deprive terrorism of its social base.
