The article deals with the development, implementation and research of the spectrum analyzers that can be used in sensor networks and Internet systems of things. As an operating frequency range, 2.4–2.5 GHz ISM is selected. At the stage of hardware selection, a comparative analysis of existing available microcontrollers for the analysis of the spectrum, the choice of hardware interfaces, the ordering of the required modules and electrical components, as well as the input control is carried out. During development, several variants of spectrum analyzers on the basis of microcontroller and TI Chipcon СС2500 microcontrollers with USB interfaces, as well as Cypress CYWUSB6935 modules with LPT and USB interfaces, have been implemented. At the development stage, the development of the printed circuit board, its fabrication, component assembly, microcontroller programming, the verification of the assembly's robustness, making corrections, connecting to a personal computer and assembly in the case have been carried out. An analysis of existing software for collecting information on the state of the wireless broadcast is also conducted. According to the results of comparative experiments of various collections of spectrum analyzers, spectrographs for different types of signals were obtained. On these typical spectrographs a comparative analysis of the work of various prototypes was conducted. The offered approaches to building sensors on the basis of spectrum analyzers allow to create low-power modules for embedding in existing wireless information networks of enterprises for prevention of inter-channel interference and ensuring the integrity of data transmission. As a result of experiments, it is evident that not all existing modules are very different in characteristics, and the quality of their work is directly related to the type and quality of the antenna. The article gives the basic electric circuits, a list of elements, examples of PCBs, programmers, software and prototypes.

The actual task of finding the optimal strategy for control the procedure of mutual financial investments to the situation center for cyber security on transport. The aim of the work – the development of a model for a decision support system on the continuous mutual investment in a cyber security situational center, which differs from the existing ones by solving a bilinear differential quality game with several terminal surfaces. In order to achieve the goal there was used a discrete-approximation method for solving a bilinear differential quality game with dependent motions. Application of this method in the developed decision support system, unlike existing ones, gives concrete recommendations ft choosing control decisions in the investment process. The proposed model gives concrete recommendations at choosing strategies in the investment process at the creation of a protected situational center. In the course of the computational experiment, there was considered a new class of bilinear differential games that allowed adequately to describe the process of investing in cyber security means of situational transport centers in Kazakhstan and Ukraine. For the first time, there was proposed a model describing the process of mutual investment based on the solution of bilinear equations and a differential quality game with several terminal surfaces. Considered the peculiarity of the differential game on the example of mutual investment in the means of cyber security of the situational transport center. In this case, the right-hand side of the system of differential equations is represented in the form of bilinear functions with arbitrary coefficients. The model allows to predict the results of investment and to find strategies for managing the investment process in the protection and cyber security systems of the situational transport center

Recently, special attention at implementation of the necessary level of information security is given to wireless technologies. Their use contributes to the growing demand for video information services. This is accompanied by an increase in the intensity of video streams and an increase in the processing time of video information, resulting in them far beyond the bandwidth of networks. Consequently, there is a contradiction that is caused: on the one hand, the growth of requirements for the quality of video information; on the other hand, difficulties in providing services of the given quality using wireless technologies.The article deals with issues related to the speed of the video stream of video information, depending on the quality of video data required, from spatial resolution and frame rate. The article concludes that with the trend of increasing the amount of video information in the complexes of the Hellenic Republic - it is necessary to improve the coding methods. In order to increase the efficiency of management and operational activities, it is proposed to improve the existing methods of encoding dynamic video streaming object with algorithms for motion compensation for video conferencing in the system of troop control. As a result, the article proposes a six-point algorithm for search, which can increase the efficiency and reduce the processing time of video information between subscribers. This approach, in the future, by improving the existing methods for encoding dynamic video streaming objects with algorithms of motion compensation, will improve the efficiency of using videoconferencing, for example, in the control system of troops.

The article considers and analyzes the determination of the reliability of information, objects and subjects of information, which will become the first step for the development of such a method that will affect the reliability of information resources. The term reliability of information should be understood as the proximity of information to the original source and adequate perception of the object of consideration by the subjects of the information space. As objects of information security act a person, society and the state. All types of information that meets the needs of the subject meet such properties as the confidentiality, integrity and availability of information. As to the impact on information and its processing, the greatest interest is threats. The threat in its general form will be any potentially possible adverse effect on objects that (which) causes damage to the subject of information activity. Recently, the influence on the reliability of information has become much widespread, and therefore there has been a phenomenon like false information. For a simple example, this is news, social networking sites, fake rating sites, by which certain groups of people or individuals draw the attention of society to incorrect events in the wrong way. Such information, in particular, is unreliable, is spreading at a high rate, gradually being replenished with new details that are the reaction of individuals. The ways of appearance of inadequate information are considered. Also, recommendations are provided to identify false information. Given the fact that the reliability of the information depends on the publications itself, analysts should pay attention to the source, carefully study the facts underlying the information, carefully check the questionable information. An unreliable researcher should consider information coming to the information space from "confidential" sources, even if the material contains a link to the organization represented by the "source".
