The basis is a comprehensive model that takes into account the technical and organizational parameters of the information system and the risks associated with them. The level of security culture of the information system is assessed on the basis of building an additive model. The model includes the characteristics of system state clusters. Clusters are formed on the basis of arrays of factors that correspond to different classes of information security culture. Classes are formed on the basis of sets of factors. Their impact is assessed using the severity of the consequences for the level of cybersecurity of the information system. In addition, the probability of manifestation of this factor in a particular information system is determined. The value of coefficients and probability distributions for each cluster and set of factors is estimated by expert methods and on the basis of a survey. A feature of the formation of arrays of factors is the inclusion in each cluster of a factor that reflects the passive behavior of the user to negative factors. Thus, the model introduces the probability of rejection of negative factors and the probability of ideal behavior for the formation of the appropriate class of threats. It is proposed to determine the average weights of the factors of the level of influence on the cybersecurity of the information system on the basis of the weighted average indicator.

The paper compares the programs of multicycle information output and its bicyclic analogue for discrete-analog means for the information display systems. The significance of the influence of bicyclic information models on the minimization of machine time resources of a single-chip microcontroller is shown. It is determined that in order to reduce resource consumption in the developed solutions it is necessary to focus on the maximum possible optimization of program blocks that are executed during interrupts and serve the I / O subsystem of the microcontroller. In this sense the bar graph displays based on the bicyclic additive information model has the best results. It was found that the traditional approach to assessing the effectiveness of programs using special benchmark programs, with subsequent measurement of code and execution time of the entire program does not allow to correctly assess the effectiveness of the program and the work of microcontroller at the device design stage. Therefore, as an alternative, it was proposed to use the size of the bytecode of the program and the speed of the main cycle - the procedure of information output to assess the effectiveness of the program. It was found that in terms of speed of execution and consumption of resources, the multicycle version significantly loses to the bicyclic program. Also, reducing the number of image formation cycles in the information field is one of the most effective way to minimize the consumption of microcontroller resources for display services.","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":"124348771","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}

There are active and passive methods of protection against laser acoustic reconnaissance systems (ACS). Active methods use various noisy or vibrating devices that pose a danger to human health. With passive protection, it is recommended to use either special corrugated windows or completely closed shutters, which create some inconvenience now. Detecting a working laser microphone is very difficult and in some cases technically impossible. For example, the removal of information using ACS occurs through glass building structures, usually windows. This article is devoted to the analysis of the principle of operation of laser systems of acoustic intelligence and passive methods of reading acoustic information. Triangulation laser sensors are designed for non-contact measurement and control of position, movement, size, surface profile, deformation, vibration, sorting, recognition of technological objects, measuring the level of liquids and bulk materials. Accordingly, they can be used to study the vibrational properties of glass and films applied to them. It is described the method of working with laser triangulation vibration sensors, which allows to study the deviations of glass from different manufacturers from sound vibrations, thereby investigating the anti-laser properties of existing glass, as well as different types of spraying and films. In addition, this method allows you to conduct and test deviations from sound vibrations for new types of glass, films and spraying, proving the results of spectral studies and their impact on the amplitude of vibration of the glass. The vibration sensor was adjusted and the software parameters were experimentally optimized to obtain the truest deviation values ​​required to work with sprayed samples for passive protection.","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":"131453655","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 analysis of the existing software for editing calibration tables in electronic engine control unit, which has tools for determining calibrations and data recognition, was carried out. The limits of use of such software products are conditioned by a small number of specified classes of calibration tables and low data processing speed. The analysis of testing results of classification methods using spectral decomposition demonstrated that a system based on this method requires complex transformations of the results of spectral decomposition. The use of spectral decomposition as a solution of the classification problem is possible if some characteristics of the input data are determined and used as data for classification. It was developed a data classification algorithm that uses characterizers to compute a clearly identified characteristic of the input matrix. The software package for the implementation of the developed algorithm was carried out by using the .NET Framework and the C # programming language. The testing of the classification system performance performed by using the developed software system on a small sample of maps. The results of preliminary testing showed that the system determines correctly the class of the provided card after training. Further testing on the Mercedes-Benz Bosch EDC16C31 / EDC16CP31 car block family showed that in cases of a large number of training images, the result meets the requirements.

It includes the development of forecasting models and algorithms, as well as the allocation of resources to take immediate action in the event of such situations, as well as information about potential hazards, risks and possible consequences. With the use of geodetic surveying and computer processing of the surveying results, the coordinates of land plot plans were obtained. Satellite images were used to obtain data on changes in soil cover over a large area and on a large scale. Aerial photographs reveal small changes in soil structure, indicating signs of erosion or other degradation processes. Digital electronic terrain maps provide geographic information about an area, including geological and geomorphological features. They are used to combine other data, such as satellite images or aerial photographs, and create a comprehensive picture of the state of the soil. In the course of research, the system of ecological monitoring of soil cover using the method of infrared spectrophotometry was improved. The method of physico-chemical analysis of soil samples is substantiated and the dependence between the state of soil contamination by individual chemical elements and their genesis is established.

The main threats are aimed at interception, violation of the confidentiality and integrity of transmitted data, attacks on the availability of nodes of the transmission channel and their substitution. Due to its characteristics, the wireless data transmission environment creates potential conditions for eavesdropping on network traffic and uncontrolled connection to the wireless network by attackers who are in its range. Wireless networks, unlike wired networks, are extremely vulnerable to possible attacks and unauthorized access due to the use of radio spectrum and the broadcast nature of the physical layer. To intercept data, it is enough to be in the range of the Wi-Fi network. Therefore, an attacker, being at a safe distance, can use wireless devices to carry out attacks. The article analyzes a cyberattack of the \"War Driving\" type on wireless networks. The analysis carried out in the article showed that there are open wireless networks. Wireless networks are open or because the administrators who configure them are not security aware. A full-scale simulation of a \"War Driving\" attack was carried out. Real-time simulation data show that 10.1% of networks do not use any encryption. The detection error of access points not using encryption is from 8% to 12%. This is a very good result and confirms the adequacy of the conducted full-scale modeling. Based on the analysis of the results of live simulation, recommendations have been developed to protect the wireless network from a \"War Driving\" attack.
