REVIEW AND ANALYSIS OF TOOLS FOR CREATING A CORPORATE ENVIRONMENT

Abstract

The article is devoted to the analysis of modern approaches to creating unified information environments for organizations with a branched structure of departments. Particular attention is paid to the use of modern tools for organizing remote access for external users and integration with the enterprise's local network. In the conditions of the need to integrate local networks of departments located in different regions, solutions based on virtual private network (VPN) technologies, port forwarding (PAT) and DMZ functions are considered. The purpose of the work is to analyze the means of creating a corporate environment with minimal funding. Methodology. Analysis of scientific literature on the creation of a corporate environment. Analysis of regulatory documents on the configuration of various routers. On the basis of system analysis, options for creating a corporate environment in conditions of rapid implementation of new technologies are proposed. The scientific novelty of the study lies in the substantiation of options for creating a corporate environment in conditions of limited funding. It is proven that DMZ and PAT technologies can be used on all modern routers as a means of creating a corporate environment. It is established that the use of VPN network technology on client computers has significant disadvantages and can be applied subject to additional configuration. Conclusions. The paper analyzes in detail the features of implementing remote access to corporate resources by configuring DMZ, PAT and VPN (PPTP, L2TP) on different router models: Tp_link TL-WR840N, Mercusys AC12g, Tp-link AX1500 and Mikrotik. Based on practical experiments, the advantages and disadvantages of each method are assessed. The analysis allows you to accelerate the creation of corporate networks within limited budgets, in particular for small businesses and educational institutions. Recommendations are presented for the modernization of network infrastructure, the selection of routers and the implementation of access control tools that can be used to build integrated information systems in business, education and other industries.
