Periodic nature of the discrete control devices operation is the reason for the appearance of pure delay in the control channels. Methods for studying linear impulsive time-delay systems in synchronous-in-phase modes of operation of discrete devices are developed with sufficient completeness. At the same time, the methods of modeling and research of multiple-time-scale, multivariable, nonlinear impulsive time-delay systems require their further development. In this paper we propose a method for modeling impulsive time-delay systems based on dynamic graphs.\u0000\u0000The result of simulation of pulse systems with delay based on dynamic graphs is completely the same as the results obtained by the modified Z-transformation. In the case of one-dimensional systems, calculations are much easier to perform on the basis of the proposed method of dynamic graphs. The application of the modified Z-transformation for analytical studies is particularly problematic in the case of multi-dimensional pulse systems with delay, as it is accompanied by difficulties of a fundamental nature due to the structural complexity and the problem of formalized mathematical description of the processes using the traditional approach.","PeriodicalId":205855,"journal":{"name":"NBI Technologies","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116946101","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}

With regard to the study of the quality of communication network management, it is advisable to describe their properties of timeliness (efficiency), effectiveness and resource consumption.

The target attack is always built under the object of influence, being a thoughtful operation, not a simple technical action. Target cyber attack on the element of information and telecommunication network is implemented in the form of a set of activities aimed at studying the information system and software. This allows for revealing weaknesses in the structure of the information and telecommunication network. The authors develop the technique of hidden introduction and bypass of standard means of information protection, fix the infrastructure, distribute the harmful action. Under the impact of a targeted cyber attack, it is difficult to choose the methods and means of protecting the information and telecommunication network, as their resource is limited. One of the ways to resolve this contradiction is a differentiated approach to the protection of information and telecommunication network, which is to choose the most relevant for the current situation areas of protection. The article deals with the problem of targeted attacks proliferation and describes the principle of their realization. The authors also substantiate the need of working out the methodology for estimating the impact of targeted cyber attacks by the enemy on information and telecommunications networks as well as their key elements. The special attention is paid to the purpose and structure of this methodology.

Sometimes anonymity on the Internet helps to protect everyone’s right. Anonymity on the Internet also helps to protect against possible illegal actions of third parties. There is a number of technologies that you can use to monitor site user activity. These include technologies such as cookies and fingerprints. Today, cookies technology is an important component of most operations on the Internet. This technology is considered to be one of the main tools that Internet resource owners use to track customers. However, this technique is gradually becoming obsolete and often does not give the desired effect. Fingerprint technology is a global identifier. Browser typos make its owner more recognizable not only on frequently visited Internet resources, but also in other electronic sources. Fingerprints capture the holistic picture that a resource receives from a web browser. This allows you to identify the client even if you make changes to your browser settings. This article deals with the problem of anonymity preservation in a network.

The Internet of things consists of loosely connected disparate networks, each of which is deployed to solve specific tasks. For example, in modern cars there are multiple networks for controling the operation of the engine and other systems, for supporting third communications, etc. The offices and residential buildings are also equipped with many networks for controlling heating, ventilation, air-conditioning, telephone, security, lighting. As the Internet of things evolves, these and many other networks will be connected to each other and gain a higher level of security. As a result, the Internet of things will gain even more opportunities to open up new, broader perspectives for humanity. This article is devoted to the popular concept the Internet of things.

To protect data processed in corporate information systems, it is advisable to ensure the information security of the system, to identify and predict threats to information security violations. Such measures will ensure effective management of information security and high-quality response to threats in corporate information systems in real time. Thus, the research of threats management and information security of corporate information systems allows the authors to develop a model of threat profile. The difference from the previously proposed models is that the present solution defines the actions that need to be taken when threats are detected and to prevent them. Application of the proposed model will allow implementing special procedures of information security management of the enterprise, using private information security policies for corporate information systems. The authors highlight the key aspects of managing threats to information security of corporate information systems. The vulnerabilities typical for corporate information systems have been allocated. The sources of threats have been formed, and the potential violators have been described.

As it turned out in the course of this research work, locally stored software data on the device is not given enough attention in terms of protection, as in some cases, this protection is based solely on the mechanisms of the operating system of the device. For more reliable protection of locally stored data of the application it is necessary to implement the following approaches in the application: encryption of both the database in full and some critical data in it separately by an additional layer of encryption; encryption of files that appear during the program execution (media files, for example); coding and representation of data in a program using proprietary algorithms; the use of confusing names of critical files and data (the key file should not be called “key”, as in the case of WhatsApp), and data traps; the encoding of the configuration files containing sensitive information to ensure the security of the data; making the functionality of the kernel cryptographic transformations in a separate plug-in library in order to make the study of the decompiled source code on the subject of these reforms meaningless.","PeriodicalId":205855,"journal":{"name":"NBI Technologies","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125431641","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}
