The article is devoted to the overview of encryption protocols using for instant messaging systems – messengers, and to the development of system, that excludes the considered security flaws. Analysis of using security model development is carried out.

The article describes the preparation process of software complex (package) consisting of secure corporate chat and DLP (Data Leak Prevention) system in the form of security monitor. Software development, project architecture, testing and other creation stage are demonstrated. The operation processes of security monitor are shown; the functionality of software package DLP–system is considered.

As a rule, during the choice of the most viable organizational structure of a cluster, traditional methods of the assessment of economic efficiency are used, taking into account the influence of financial, production and technological risks. The high level of the fluctuations of social, political, economic and technological impacts of the intercountry level has a strong impact on the result of their production activities. The peculiarities of this influence include the emergence of new institutions of interaction between the subjects of a cluster, the growth of uncertainty within the system and a change in the level of specificity of the assets of its participants. The task to find new tools for the assessment of the potential of economic security of a cluster is becoming urgent. It is necessary to find such tools which would take into account the ability to adapt to technological and geopolitical challenges in the future. Within the framework of this study, the authors developed an algorithm for the assessment of the potential of alternative models of the organizational structure of a high-tech cluster. The important methodological aspect of the process of forecasting the level of adaptability of alternative cluster structures to external changes is the condition for the availability of institutional support to promising areas of technical development. The developed algorithm presupposes the further development of the methods of system analysis and the formation of Institutional Atlases for the parameters of the assessment of the opportunistic behavior risks of subjects or synergistic effects. The use of this algorithm allowed drawing some important intermediate conclusions about the unequal composition and the influence of dominant institutional factors in modeling different organizational structures of a high-tech cluster.

The article is devoted to the issues of practical implementation of planning observations of information processes flows, the sources of which are dynamic network objects that can appear in the network at random times. A variant of the implementation of the suboptimal distribution of time resources of the monitoring system between the tasks of detecting and evaluating random processes that appear in accordance with the laws of the Poisson flow is proposed.

The article discusses the risk assessment methods, the influence of safety threats on the occurrence and likelihood of risks, the difficulties encountered before risk assessment, raises issues of planning and extent of the construction entity's influence on risk assessment and construction protection. Particular attention is paid to the processing of results and analysis of threat assessment. An assumption is made that planning can be used as a risk assessment tool, and a way of using this tool to protect against emerging threats is suggested.

There are methods for determining the quantitative and qualitative need for labor in the paper. The methods of recruitment are analyzed. Classification of methods of recruiting is given. Their advantages and disadvantages are revealed. The paper presents the results of a study on modern methods of recruiting personnel used by construction organizations in Tyumen.

The purpose of this paper is to analyze actual stress-strain states of casting crane traverse taking into account weight of lifted load, thermal effects and additional inertial loads. The object of the study is a pattern of stress distribution inside the traverse elements. Methodology is proposed for modeling and analyzing stress-strain states of the casting crane traverse based on strength calculations considering allowable stresses and FEM. Calculation scheme and equivalent model were developed, and FEM calculation was performed in CAD/CAE system. Regularity of stress distribution in the traverse is obtained, and possible ways to further research are identified.

This article presents some methods for calculating the residual life of building structures. Areas of application for each of them are highlighted. A new method for calculating the residual life of building structures is proposed, which is proposed to be called a combined procedure for calculating the residual life of building structures. This method outlines a methodical approach that involves the joint use of all the techniques listed in this article. This will remove the limitations that each of these techniques had individually, which makes the combined methodology a universal technique for calculating the residual life of building structures. Combined methodology with its further improvement allows the use in some cases of special methods for calculating the remaining resource.

The article is devoted to the problem of normative and legal regulation of incentives for workers of the building companies. The company considered is engaged in high-rise construction. The part of the document “Regulations for the incentives of employees of the enterprise” is presented. This document is introduced into the practical activities of the Tyumen enterprise. The presented part of the document regulates the issues of material incentives for employees of the enterprise. The document “Regulations for the incentives of employees of the enterprise” is developed in accordance with the approach proposed by author. The document was developed, after the authors had carried out an analysis of the scheme of incentives at the enterprise.
