Abstract

The article analyzes the problem of secure connection of a remote client to the internal computer network of the higher education institution. The most commonly used OpenVPN, Libreswan and WireGuard solutions were evaluated. The analysis of the literature showed that the OpenVPN solution is the most suitable for implementing a system for secure connection of remote clients to the internal computer network of the higher education institution. OpenVPN is easy to administer, able to read certificates and private keys from the most popular operating systems, uses two-way certificate authentication. Has been analyzed and assessed the needs of higher education institution users. The study of requirements for technical equipment was carried out. A conceptual model of the projected system has been prepared. A virtual model of the designed system was implemented and tested using cloud computing solutions. Checked the availability of internal network services. Evaluated encryption of transmitted data.
