Technologies and methods for creating systems of secure information exchange

This article presents a description of existing technologies and methods for creating secure information exchange systems. To date, secure information exchange systems are built in accordance with two technologies – VPN technology and cryptographic protocols SSL and TSL, as well as in accordance with combinations of these technologies. The necessity of creating network security systems is considered. The rapid development of network technologies leads to an equally rapid increase in information security risks for companies in both the public and private sectors. The requirements of the legislation of the Russian Federation in the field of ensuring the security of networks are presented. The principles of network security design are described. The analysis of existing projects and implementations of network security was carried out. A description of the existing and methods for constructing secure information exchange systems is given. The technologies for building secure information exchange systems based on VPN technology, as well as the algorithms for building VPN connections – PPTP, IPSec, L2TP, SSTP, OpenVPN, GOST VPN are considered. The most common technical and software information security tools that use VPN to build a secure information exchange are described – the products of the companies InfoTeKS, Security Code, S-Terra. The technology of constructing secure information exchange systems based on SSL and TLS cryptographic protocols is considered. This article identifies the most common problems in building secure information exchange systems – the presence of a large number of manufacturers of information security tools with their own ecosystem, as well as high labor, financial and time costs for ensuring the information exchange of systems of different levels of security, the security of which built on solutions from different vendors.
