The article discusses problematic issues of creating countermeasures against the impact of a potential violator on complex organizational and technical systems, such as information infrastructures of government agencies and enterprises. The high importance of automated control systems for the implementation of technological cycle tasks, as a result of their basic element, a distributed computing network, creates prerequisites for the impact of an intruder on it in the event of conflict situations.

Goal – solving the problem of ensuring the sustainable functioning of complex organizational and technical systems by making changes in their configuration to fend off emerging threats. The novelty of the work lies in the systematic consideration of a model of a complex organizational and technical system at various stages of operation, as interrelated topological and information structures that form information paths for solving information and computational problems at the required time intervals. At the same time, the embedded algorithm for managing the restructuring of automation complexes has an adaptive mechanism that selects a rational solution to ensure the established criterion for fulfilling the objectives of a complex organizational and technical system.

A model of the reconfiguration process of automation complexes of a complex organizational and technical system and an algorithm for assessing the survivability of automation complexes of complex organizational and technical systems, which is based on the principle of using the provisions of Markov chain theory, which, unlike the known ones, makes it possible to determine the survivability of automation complexes of a complex organizational and technical system and its elements by assessing the level of transformation of target tasks. at a given time interval, considering the factors of reconfiguration of automation systems depending on the forecast of the violator's actions.

The practical significance lies in the suitability of the developed scientific and methodological apparatus for solving practical problems of ensuring (restoring) the operability of complex organizational and technical systems, a wide range of activities that arise during hardware failures and software failures of automation systems under destructive influences.
