This article addresses the problem of protecting the private property of a protected object, namely: it offers an algorithm for recognizing object movements using a neural network for the CCTV system. The ability of the perception of the outside world in the form of images allows to investigate with certain probability the properties of an infinite number of objects on the basis of acquaintance with their finite number, and the objective nature of the basic property of the images allows to model the process of their recognition. , namely "image", "feature", "vector implementation". The approaches, methods and technologies of object motion recognition are investigated, their qualitative characteristics and disadvantages are highlighted. Artificial neural networks have been found to be the most effective method for solving the object motion recognition task due to result accuracy, simplicity and speed. On the basis of the block diagram of the complex algorithm for image processing and analysis, the algorithm of object motion recognition using neural network for the video surveillance system was developed.

The improvement of protection systems is based on the introduction and use of a mathematical apparatus. Ensuring the confidentiality, integrity and availability of information is an urgent and important problem in the modern world. Crisis processes are characteristic phenomena in security systems, so stochastic models cannot always describe their functioning and give a solution. An effective tool for solving this problem can be the use of dynamic models based on the provisions of catastrophe theory. This study is devoted to the analysis of modern approaches to the use of the basic provisions of catastrophe theory in cybersecurity systems. The work presents a brief historical view of the development of this theory and highlights the main definitions: bifurcations, attractors, catastrophes. Elementary catastrophes, their forms and features are characterized. A review of the literary sources of the use of catastrophe theory in information and cyber security was carried out. The analysis made it possible to single out that this theory has not yet been widely implemented, but there are point scientific developments in the process of detecting network anomalies in the cloud environment. The considered approaches to the application of catastrophe theory in information and cyber security can be used to train specialists in the specialty 125 Cybersecurity in the process of research

Biometric images were pre-processed and filtered in two ways, by wavelet- Gabor and wavelet Ateb-gabor filtration. Ateb-based Gabor filter is effective for filtration because it contains generalizations of trigonometric functions. The wavelet transform of Ateb-Gabor function was developed. The function dependence on seven parameters was shown, each of them significantly changes the filtering results of biometric images. The Ateb-Gabor wavelet research was performed. Graphic dependencies of the wavelet Gabor filter and the wavelet Ateb-Gabor filter were constructed. The appliance of wavelet transform makes it possible to reduce the complexity of calculating an Ateb-Gabor filter by simplifying function calculations and reducing filtering time. The complexities of algorithms for calculating the wavelet Gabor filter and the wavelet Ateb-Gabor filter have been evaluated. Ateb-Gabor filtration allows you to adjust the intensity of the entire image, and to change certain ranges, thereby changing certain areas of the image. Biometric images should have this property, on which the minucius should be contrasting and clear. Ateb functions have the property of changing two rational parameters, which will allow to make more flexible control of filtration. The properties of the Ateb function, as well as the possibility of changing the amplitude of the function, the oscillation frequency by the numerical values of the Ateb-Gabor filter, were investigated. By using the parameters of the Ateb function, you can get a much larger range of shapes and sizes, which expands the number of possible filtration options. You can also perform filtration once, taking into account the direction of the minucius and reliably determine the sharpness of the edges, rather than perform filtration many times. The reliability of results were tested using NIST Special Database 302 and good filtration results were shown. This is confirmed by the comparison experiment between the wavelet-Gabor filter and the wavelet Ateb-Gabor function based on the PSNR signal-to-noise ratio measurement.

National security of the state is one of the main factors of stable development of society. However, Ukraine and the Armed Forces of Ukraine are forced to counter a hybrid war using cyberspace. It has been established that currently there is no unified vision regarding the methodology of countering wars in a hybrid form. The lack of a countermeasure methodology requires a review of existing approaches to guaranteeing and maintaining state security. The purpose of the article. Justification of the need to create hybrid troops to neutralize cyber threats to the Armed Forces of Ukraine and methods of its implementation on the basis of military-civilian cooperation. Materials and methods. To solve the tasks, a set of theoretical research methods was used: historical analysis and generalization of scientific literature on the research problem; structural and genetic analysis and synthesis when specifying the object and subject of research; the method of going from the abstract to the concrete; the method of analytical and comparative analysis in the analytical and comparative evaluation of the novelty of research results; synthesis and generalization - to justify the methodological and methodical foundations of the research; generalization – formulation of conclusions and recommendations regarding the continuation of further research. Result. A key hypothesis was formed that an effective tool in countering hybrid warfare can be achieved through the use of hybrid troops. Developing this hypothesis substantiates the philosophical idea of the need to create hybrid cyber armies on the basis of military-civilian formations. Foreign experience confirms the high efficiency of military-civilian formations. On the basis of the current legal acts, a method of implementation is proposed. The practical significance of the study lies in the possibility of obtaining advantages in the cyberspace of the Armed Forces of Ukraine during active hybrid wars due to the formation of units of hybrid troops of the Armed Forces of Ukraine.

. The article deals with the problem of ensuring the fault-tolerance of Internet services. It is becoming increasingly important due to the growth of the quantitative parameters of the functioning of information systems (users, servers, volumes of information in databases) and the level of complexity. Due to the heavy load on the servers on which the applications are deployed, there is a failure of hardware or software. The urgency of finding additional ways to ensure the fault tolerance, reliability and uninterrupted functioning of computer systems operating in real time, due to the increasing requirements for the security of running processes or objects, access to which is limited. Despite the use of existing methods for ensuring fault tolerance in cloud infrastructures, there is a problem of inconsistency between the actual availability of systems and the levels of "fault tolerance" (Fault Tolerance) and "High Availability" (High Availability) for critical and business critical web applications. Also, less attention is paid to methods of improving fault tolerance for highly loaded systems. Therefore, the search for new opportunities for scaling and load balancing when building cloud systems is of particular importance. To conduct a comparative analysis of load balancing algorithms, functional characteristics were proposed, according to which it is possible to make an informed choice of algorithms that most closely correspond to specific practical circumstances and the requirements of users and providers. The basic principles for implementing a resiliency strategy now include redundancy, diagnostics, reconfiguration, and recovery. As an additional indicator of failover control, it is proposed to apply the completeness of the booking of elements and components of the system, the completeness and reliability of the control, the probability of reserve recovery. The first two strategies assume that a system that correctly performs its functioning algorithm is safe. The safe behavior strategy for failures is used specifically for safe systems and consists in the transition of the system to a protective irreversible state in the event of a failure.

The article analyzes the accrued national and foreign developments regarding the problems of digital competence formation and effective use of information technology in education. The components of digital competence are considered, which provide for a confident, critical and responsible interaction with digital technology for education, work and participation in social activities. The results of a global information security research are presented along with surveys of employees of leading cyber companies around the world, including Ukraine, that testify to the necessity of further application and implementation of an integrated approach to education using organizational measures, software and hardware means and management processes at all activity levels of any organization, as well as using the appropriate tools to raise the digital competence level. The essence of the importance of digital tools in the field of cyber security is formulated, which means a set of Internet tools (resources) to protect network environment entities against various information and cyber threats, ensuring proper organization of countering their effect, formation, functioning and evolution of cyber space and development of educational cyber technology and the information society as a whole. Three main groups of digital cyber security tools were analyzed, identified and proposed (professional cyber tools, education cyber tools and communicative cyber tools) that enable the use, access, filtering, evaluating, creating, programming and communicating digital content, managing and protecting information, content, data and digital identities, as well as working effectively with software, devices, artificial intelligence, robots and more. It is proved that present-day work with digital cyber tools and their content requires a reflective, critical and at the same time inquisitive, open and promising attitude to their development, as well as an ethical, safe, effective and responsible approach to their use

The paper analyzes the causes and ways of solving the problem of free space lack on the system partition during the OS Windows exploitation. The peculiarities of the system partition organization during the installation of common Microsoft operating systems are analyzed. The main system file objects, paths to them, their purpose and role in the use of system partition space and in the functioning of the operating system are considered. Represented the list of paths to the files of the folders that occupy the largest volumes on the system partition. Thees folders correct cleaning or configuring may save a lot of space on the system partition. The main tools of the operating system for the cleaning methods implementation are considered: command line interpretator, PowerShell environment, system registry editing tools, and system library function calling tools. Particular attention is paid to batch files as the simplest and most effective means of implementing automated use of system utilities, taking into account the peculiarities of the command line interpreter. One of the ways to manipulate objects with commands is to use the PowerShell environment. This environment is able not to process commands, but to generate streams of objects related to this command and form their processed representation using both command and graphical interface. Described the logical and physical structure of the registry as one of the tools for managing Windows settings. Was made the comparative analysis of some software products, such as the system console utility for servicing deployment and management images, as well as a number of free software. It has generated the list of functions used for the system partition optimization and cleaning from excessive data.

The peculiarities of the system partition organization during the installation of common Microsoft operating systems are analyzed. The main system file objects, paths to them, their purpose and role in the use of system partition space and in the functioning of the operating system are considered. Represented the list of paths to the files of the folders that occupy the largest volumes on the system partition. Thees folders correct cleaning or configuring may save a lot of space on the system partition. The main tools of the operating system for the cleaning methods implementation are considered: command line interpretator, PowerShell environment, system registry editing tools, and system library function calling tools. Particular attention is paid to batch files as the simplest and most effective means of implementing automated use of system utilities, taking into account the peculiarities of the command line interpreter. One of the ways to manipulate objects with commands is to use the PowerShell environment. This environment is able not to process commands, but to generate streams of objects related to this command and form their processed representation using both command and graphical interface. Described the logical and physical structure of the registry as one of the tools for managing Windows settings. Was made the comparative analysis of some software products, such as the system console utility for servicing deployment and management images, as well as a number of free software. It has generated the list of functions used for the system partition optimization and cleaning from excessive data. Based on the generated list, the efficiency of using the considered software tools for cleaning the system partition is analyzed.","PeriodicalId":198390,"journal":{"name":"Cybersecurity: Education, Science, Technique","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130633331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article presents the results of research performed in the process of designing an expert system (ES) designed to assess the threats to information security (IS) of critical information facilities (CIF). The approach to designing of expert system on the basis of syllogisms and logic of predicates, and also a method of meaningful identification of objects of knowledge base (KB) is offered. The essence of the method is that each object of the database of the projected EU, is matched by a tuple of keywords (ToK), the significance of which is determined by experts. Thus, each database object is placed in accordance with the element of the finite fuzzy topological space of the database objects. Meaningful identification takes place on the distance between the objects of the database. The approach proposed in the work, in comparison with the decisions of other authors, has a number of advantages. Namely, it allows: to model different variants of cyber threat scenarios for CIF and their consequences; determine the contribution of each of the factors or components of the architecture of the IS CIF to the overall picture of the probability of a cyber threat to the CIF; model the interaction of all IS factors and, if necessary, visualize this interaction; calculate and further rank the values of cyber threat probabilities for CIF for specific threat scenarios; automate the processes of threat modeling through the use of developed software and significantly reduce the time for audit of threats. It is shown that the use of the method of meaningful identification allows to increase the adequacy of the models of the selected subject area, as well as to prevent erroneous introduction of the same judgments of experts and goals in the EU database, in particular by combining hierarchies of goals formed by different expert groups. It is shown that the method can also be used to find the goals of the hierarchy, the exact wording of which, according to keywords, is unknown.
