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.

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 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.

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.
