Authors explore issue of applicability of the methodology of building diagnostic software using network formal models in the functional testing of electronic equipment as part of complex technical systems. Using methods of system analysis allows to perform a decomposition of interdependent subsystems and to reveal basic acts of interaction between the control‑verification equipment and the object of diagnosis. Mathematical apparatus of Petri nets should be employed for the formalized description of such acts and determined the cause‑and‑effect relations in the diagnosed complex system`s processes. Network models properties studying (such as safety and accomplishment of the final positions) allows us to move to the test object`s algorithm`s developing. The article presents an approach of a formalized description for basic acts of interaction between the diagnosis system and the object.

Issues related to information security of the enterprise are considered. Information security is a set of tools and methods used to protect digital and analog information. The purpose of the information security management system and the role of technical means of information protection from information threats to the enterprise are shown. The methodical approach of the system analysis concerning maintenance of information security of the enterprise is used. To create and effectively operate an information security system, it is always necessary to use already established practices (standards, methodologies) to build such information security systems and implement them in information security management systems. Since modern systems of information security of the enterprise, as a rather complex organizational and technical systems, operate in conditions of uncertainty of the external and internal information environment, the management of such systems should be based only on the results of system analysis. The need to rethink the approaches and methods of systems analysis to the creation and development of modern information technologies is noted. Issues of information security should be considered as components in the creation of modern information security systems - from the moment of design, at all stages of operation and support. Global campaigns - vendors of computer systems pay considerable attention to increase their capacity to protect information through the development and improvement of technical means, in which a significant place is given to timely detection of threats, their analysis and prevention of negative impacts on reducing information security. One of the world's leading IT manufacturers is FireEye, a leader in the supply of its technical solutions. An analysis of technical solutions of FireEye, which is one of the world's leading IT manufacturers in the field of information security. Innovative solutions from the FireEye company at the enterprises of Ukraine for the purpose of increase of efficiency of detection of information modern threats and protection of the information are offered for realization.

Structure Of Knowledge

The article analyzes a number of methods of knowledge formation using various graph models, including oriented, undirected graphs with the same type of edges and graphs with multiple and different types of edges. This article shows the possibilities of using graphs to represent a three-level structure of knowledge in the field of complex technical systems modeling. In such a model, at the first level, data is formed in the form of unrelated graph vertices, at the second level – information presented by a related undirected graph, and at the third level – knowledge in the form of a set of graph paths. The proposed interpretation of the structure of knowledge allows to create new opportunities for analytical study of knowledge and information, their properties and relationships.

The article deals with the issues of integrated assessment of complex technical systems stability functioning in techno sphere and info sphere. It is shown that the concept of cyber stability, including its components such as cyber reliability, noise immunity and cyber survivability are insufficiently investigated and defined. The formal definition is given and the scale with various gradation of cyber survivability is entered. On the example of robotic systems in form of drones two variants of mathematical models of cyber survivability estimation are considered. The first variant is related to the description of drones functioning in the conditions of computer attacks without impact protection systems. The second variant reflects the functioning of drones under the conditions of impacts in the presence of adaptive combined cybernetic protection system. In both variants, two strategies are considered - with minimal and maximum intensity of effects on the drone. It is concluded that proposed in the paper approach enables to evaluate the integrated stability of complex technical systems in the techno sphere and info sphere at the same time.

В работе изложены актуальные вопросы, связанные с планируемыми Министерством экономического развития Российской Федерации изменениями в стратегии экономического роста и реформой государственных программ, напрямую затрагивающих производство сложных технических систем. Также рассмотрены контроллинговые задачи научно-исследовательских структур, требующие административной основы, наравне с ранее принятыми решениями по цифровизации управления и его элементов. The paper outlines current issues related to the changes planned by the Ministry of Economic Development of the Russian Federation in the strategy of economic growth, as well as the reform of state programs that directly affect the production of complex technical systems. Besides, it proposes controlling tasks of research structures that require an administrative basis, along with previously adopted decisions on the digitalization of management and its elements.
