  A model of the relationship between the customer and the service provider of the call center to optimize the quality of information processing
• Abstract
  • Problem statement: The organization of effective information processing in call centers when purchasing data center services from a supplier involves solving a multi-criteria optimization problem of finding a cost-effective balance for both the customer and the data center service provider between the quality of information processing services required by the customer and the cost of these services for the supplier. service quality functions, the desire of the customer to minimize the costs of these services and the desire of the service provider to maximize its profits. To formalize the solution of this optimization problem, it is necessary to build a model of the relationship between the customer and the provider of information processing services in the data center, describe the parameters of this model and criteria for evaluating the solution of the optimization problem. Methods: mathematical modeling of the dependence of the service provider's profit on the quality of the service; determination of the functions of price, cost, profit, quality and usefulness of the service. Results: a model of the economic relationship between the customer and the information processing provider in call centers has been built at all stages of the service lifecycle: from the customer's intention to purchase the service to the expiration of the service supply agreement between the customer and the service provider. A model of a formalized management contour is highlighted, which allows us to solve the problem of synthesizing an effective type of dependence of an integral assessment of the quality of quality services on a vector of values of partial estimates of the quality of quality services, allowing the customer to obtain a quasi-optimal value of the value of quality services due to the economic interest of the supplier. Practical significance: the results of the work can be used to model the process of purchasing various services by the customer from the supplier in solving a wide range of other applied tasks that can be reduced to the task being solved in the work. They make it possible to significantly increase the value of the services received by the customer due to the economic interest of the supplier.

  Mathematical models for masking structural and dynamic characteristics of departmental data transmission networks against computer reconnaissance
• Abstract
  • Problem Statement: one of the methods to counter the threat of computer reconnaissance of information flows is masking the structural and dynamic characteristics of departmental data transmission networks. However, existing approaches to approximating the dynamic characteristics of information flows during masking implementation are characterized by low generalization capability and the necessity of converting non-stationary data to a stationary form using differencing transformations. At the same time, the existing scientific and methodological framework for determining probabilistic-temporal characteristics does not account for the non-stationarity of parameters of the random process assessing the security and availability of network devices, as well as the timeliness of information exchange during the implementation of masking of structural and dynamic characteristics of departmental data transmission networks against computer reconnaissance. The purpose of the work is to develop models for masking structural and dynamic characteristics of departmental data transmission networks against computer reconnaissance and to investigate, based on these models, the patterns of functioning of a departmental data transmission network during the implementation of computer reconnaissance protection procedures. Methods used: the work employs methods of machine learning, mathematical statistics, optimization, time series analysis, and random process research. Novelty: the article proposes an approach to approximating the dynamic characteristics of legitimate network traffic using an ensemble of recurrent neural network models with Long Short-Term Memory (LSTM) cells to evaluate and predict the frequency characteristic of the approximated network traffic, and an exponential distribution law of a random variable parameterized by the neural network output to obtain numerical values of pauses between packets of the predicted masking network traffic. The probabilistic-temporal characteristics of the functioning process of departmental data transmission networks during the implementation of masking of structural and dynamic characteristics under conditions of computer reconnaissance have been determined using the mathematical apparatus of the theory of non-homogeneous Markov and homogeneous semi-Markov processes with discrete states and continuous time. Practical significance: formation of masking network traffic whose dynamic parameters are statistically close to legitimate traffic, and obtaining probabilistic-temporal characteristics of the functioning process of departmental data transmission networks under conditions of computer reconnaissance and network traffic non-stationarity, necessary for formalizing the objective functions of masking effectiveness, network device availability, and timeliness of information exchange when formulating the problem of vector optimization of masking parameters for structural and dynamic characteristics. Result: a system of models for masking structural and dynamic characteristics has been developed, allowing the investigation of the functioning of departmental data transmission networks under conditions of computer reconnaissance.

  Integration of technical and organizational measures to protect the Active Directory domain: from network segmentation to incident monitoring system
• Abstract
  • Purpose. In conditions of high dependence of corporate infrastructures on the domain architecture of Active Directory, domain protection is considered as a key element of ensuring the stability of the entire information system of the organization. However, operational practice demonstrates that even with a variety of technical means of protection, AD compromise remains possible due to the lack of system integration of technical and organizational measures. There is a fragmented implementation of security solutions, inconsistency in administration and monitoring procedures, as well as a gap between the security architecture and its maintenance processes. The purpose of the work is to develop an integrated Active Directory domain protection model that combines technical and organizational measures at all levels of the infrastructure — from network segmentation to an incident monitoring system — with formalization of criteria for their criticality and interrelationships. Methods. The methodology is based on a system analysis of domain infrastructure, decomposition of protection levels, analysis of the MITRE ATT&CK matrix, the method of expert assessments of the criticality of measures, as well as analysis of Windows event logs to build a monitoring model and incident correlation. Novelty. A five–level integrated Active Directory protection model is proposed, considering a monitoring system (SIEM-EDR) as an integration layer that combines technical and organizational countermeasures into a single layered architecture. A classification of measures according to the level of criticality has been introduced, depending on their position in the attack chain. Results. A structured model for the integration of technical and organizational AD protection measures has been developed, tables of matching attack vectors and countermeasures have been formed, priorities for monitoring Windows events and criteria for the criticality of protective measures have been determined. Practical relevance. The proposed model makes it possible to build a domain infrastructure protection architecture taking into account the limitations of real organizations, justify the priority of implementing measures, increase the effectiveness of incident response processes and rationally allocate the information security budget.

  The third decisive scheme is a promising new direction for improving the efficiency of receiving and processing complex broadband noise-like signals
• Abstract
  • Relevance: At certain stages of the development of the theory and practice of designing and creating information transmission systems (ITS), certain scientific and technical categories and concepts were formed (as objectively necessary), which made it possible to carry out research (analysis and synthesis) at a systematic professional level ITS; professional and special dialogue between scientists, designers, practitioners; progressive development of the theory of ITS. For example, the categories that have abbreviated the process of using information signals in ITS – simple and narrow–band – in particular, include: "first" and "second" formative circuits (FFC and SFC), "first" and "second" decisive circuits (FDC and SDC). Since the beginning and widespread use of complex broadband signals (broadband noise–like signals – BDLS or BBS) based on pseudorandom sequences (PRS), complex discrete and digital methods of modulation, digital communication, etc., the processes of formation, reception and processing of BBS required the introduction of new scientific and technical professional methods. necessary categories, for example: "broadband modulation", "correlation reception", etc. And the tasks that have arisen are to develop and study the correlation properties of all new classes of BBS with improved noise-proof and special properties (in terms of secrecy, imitation resistance, cryptographic resistance, etc.), for example, – classes of derivatives and composite BBS have led to the need to: review the validity and expediency of using the thesis "randomness" in relation to the correlation functions (CRF) of BBS, and introduce into theory and practice the thesis "determinism" of the CRF of BBS to improve the efficiency of receiving and processing BBS and the reliability of information transmission within the framework of new methods and scientific and technical schemes. Over the past 20 years, the authors of this article have begun to refer to such methods and schemes as an emerging new necessary category – the "third decisive scheme" (TDS) – as a set of algorithms, mathematical models, methods and technical solutions –devices that significantly improve the efficiency of reception and processing procedures, primarily derivatives and composite BBS based on the use of properties and patterns of determinacy of the CRF BBS. The aim of the paper is to review the scientific and practical publication process for the development of the TDS category and the study of the properties and patterns of the CRF PRS (as the basis of BBS) in the form of derivatives of nonlinear recurrent sequences (NLRS), which have the most promising (currently) and wide range of applications in ITS, which are subject to high requirements for noise immunity (noise immunity, various types of stealth type, image security), cryptographic stability, and information security in general. Methods used: modeling (mathematical, structural), including machine modeling, mathematical formalization of the properties and patterns of determinism of the CRF. Results. The article provides an overview of the results of modeling the TDS method, the properties and patterns of determinism of the CRF (partial auto- and intercorrelation functions) of the NLRS, and technical solutions for the implementation of TDS. Practical significance. Is to acquaint specialists in the field of BBS with the essence, results of the development of methods and methods of TDS, studies of the properties and patterns of determinism of the CRF of NLRS, which have certainly wide practical application.

  A model for generating multi-frequency control command signals for unmanned transport systems under interference conditions
• Abstract
  • Problem Statement: currently, the Russian transport industry is rapidly developing unmanned technologies in key areas of scientific progress. It is important to take into account that the use of aviation, space, land, sea and river unmanned transport systems at global ranges or within the city is accompanied by the use of wireless technologies based on radio channels of various wave ranges, which are subject to the destructive effects of noise, interference, fading and other destabilizing factors. In turn, it can be stated that the radio frequency spectrum has long been divided between licensees and continues to be overloaded due to the explosive growth in the introduction of autonomous systems by departments, especially in large metropolitan areas and transport and logistics hubs in ports and industrial agglomerations. At the same time, increasing the number of high-speed autonomous systems, sometimes operating at hypersonic speeds, requires developers to develop new approaches to bring control commands in real time. The article aims to develop a model for the formation of multi-frequency control command signals for unmanned transport systems transmitted in parallel transmission mode of each bit over available interference-free radio channels. The purpose of the work: to develop a model for the formation of multi-frequency control command signals for unmanned transport systems in conditions of interference based on the use of intelligent technologies. Methods used: methods of dynamic control of the radio frequency spectrum based on technologies of spectrum expansion with a change in the operating frequency according to a pseudo-random law, spectrum expansion by direct sequence method and spectrum expansion by linear frequency modulation method, technologies of cognitive radio systems and software-defined radio. The main results of the study include the regulatory and legal justification of the need for dynamic control of the frequency resource in conditions of interference, the determination of the initial data for modeling and the model itself for the formation of multi-frequency signals of commands for controlling unmanned transport systems in conditions of interference, the verification of the proposed model for adequacy, the schematic implementation of a multi-frequency signal generator for commands for controlling unmanned transport systems in conditions of interference, and also suggestions on the directions of further research. The novelty consists in presenting a geometric model for the formation of multi-frequency control command signals for unmanned transport systems at different signal level thresholds against the background of noise and interference in the command radio link, as well as calculating the probability of correct reception of a control command signal with a varying frequency band depending on the ratio of the frequency band width under interference and free from it. The practical significance of the model is its use in the synthesis of a promising intelligent control system for unmanned vehicles of the department based on data from monitoring their condition and operating environment.

  Contoured Beam Control Method for an Onboard Reflector Antenna
• Abstract
  • Purpose. In the development of satellite communication systems, it is necessary to ensure the required quality of service within a specified service area, which may have a complex boundary shape. To cover this area, onboard antenna systems forming a contoured radiation pattern are used. The requirements for the parameters of this radiation pattern may change during the system's operation, which can be due to refinements in the service area boundary shape or changes in the relative position of the spacecraft and the service area over time. Several methods exist for implementing a specified radiation pattern in antenna system design. Among them, a promising approach is the use of a reflector antenna with a single feed and a profiled metallic reflector, whose surface primarily determines the parameters of the main beam. However, a relevant challenge is enabling control over the radiation pattern parameters, which is a primary limitation. Novelty. To overcome the mentioned limitation, a new method is proposed, which involves the relative geometric displacement of the reflector elements, thereby generating the required near field. Results. The results of radiation pattern calculations for independent (uncoupled) aperture configurations of the reflector antennas confirm the feasibility of the proposed method. Its application enables control of the contoured radiation pattern of the onboard reflector antenna with a single feed and a profiled reflector. Practical relevance. The actuating devices within the antenna system that implement the proposed method are mechanical components, whose parameters are more resilient to the factors of the space environment compared to radio components.
