Solving the problem of maintaining the constant availability and relevance of information under the influence of malware is one of the important scientific problems in the field of information technology (IT), focused on the construction and further operation of specialized information systems (IS). In the dissertation, an analysis of the threats posed by PPE for the functioning of IS was carried out, methods were developed to ensure fault tolerance, survivability and information protection of specialized IT, which improve their resistance to the effects of PPE, appropriate tools were developed and experimental research was carried out with them. The object of the study is the process of ensuring fault tolerance, survivability and protection of information of specialized IT in the conditions of the effects of PPE. The subject of the research is methods and algorithms for ensuring fault tolerance, survivability and information protection of specialized IT in the conditions of the effects of PPE. The aim of the dissertation research is to improve the fault tolerance, survivability and information protection of specialized IT under the effects of PPE. Scientific novelty of the obtained results: 1) a method of ensuring IT fault tolerance according to the integration of redundancy components has been developed, which, in contrast to known methods, makes it possible to expand the capabilities of IT in terms of their adaptability to reconfiguration, which allows creating fault-tolerant IT with respect to the effects of PPE; 2) a method of ensuring the survivability of specialized IT has been developed according to the analysis of markers and stored information for self-examination, which, unlike known methods, stores information about key processes and carries out their self-analysis, which improves ensuring the survivability of IT in the conditions of the effects of PPE; 3) a method of ensuring the protection of specialized IT information was developed, which, unlike the known ones, combines organizational measures with the integration into IT of methods of network segmentation, cryptographic protection, two-factor authentication of software, creation of false attack objects, backup, which allows creating means of improved protection of information in the conditions of the effects of PPE; 4) for the first time, a method of ensuring fault tolerance, survivability and protection of information of specialized IT was developed, which, unlike the known ones, consists in the integration into IT of methods of ensuring fault tolerance, survivability and protection of information according to their coincidences in states when responding to the effects of ZPZ, which made it possible to create IS with improved fault tolerance, survivability and information protection characteristics. Practical significance of research results. Means of ensuring fault resistance, survivability and protection of information of specialized IT have been developed, which integrate developed methods of fluidity according to their coincidences in the states when responding to the effects of ZPZ. This made it possible to develop IS with improved fault tolerance, survivability and information protection characteristics. The effectiveness of the method of ensuring IT fault tolerance according to the indicators of redundancy and automatic configuration change was 87%, and when integrating the method of ensuring fault tolerance, survivability and information protection into IT, it was 67%. The theoretical and practical results of the research are implemented in the IS of KhNU, during the creation of IT in LLC "ITT" and LLC "Deimos", in the educational process of KhNU. The relevance of the scientific problem is justified in the introduction. The connection of the research topic with the scientific works of famous researchers of this problem in the world is presented, and the main scientific results of the work and its practical significance are reflected. In the first chapter, the analysis of the subject area of the study was carried out, and the statement of the research task was performed. The second chapter presents the development of a method for ensuring IT fault tolerance according to the integrated involvement of redundancy components and redundancies, and its effectiveness is substantiated. In the fourth chapter, a method of ensuring fault tolerance, survivability and information protection of specialized IT is developed, which consists in the integration into IT of mechanisms for ensuring fault tolerance, survivability and protection of information according to their coincidences in states when responding to the effects of cyber attacks and computer attacks, which made it possible to create specialized ICs are resistant to these influences, and the architecture of the tools in which it is implemented and its effectiveness are presented. The scientific and practical results of the research are presented in the conclusions.
