The main goals of ensuring the information security of industrial networks are the ensuring data and tags integrity that transmitted over industrial communication channels, preventing the interruption or complete stop of automated technological processes. To do this, it is necessary to use an effective technical device that ensures the security of information transmitted via a communication channels in industrial automated control systems operating at industrial enterprises in the Russian Federation using the concept of import substitution. In the article, we make the compare of technical devices ensure information security by means of calculation the evaluation of information security. This research aims at identifying the most effective technical device that increases the level of information security protection of the OCII and reduces the costs of information security systems creation and/or modernization. © 2022 SPIE
