The current requirements for firewalls (ME) were approved by FSTEC on September 12, 2016. At the same time, methodological documents were officially published containing firewall protection profiles for 5 types and 6 classes of firewalls.

FSTEC identified the following types of firewalls:

ME type "A" - ME used on the physical boundary (perimeter) of the information system or between the physical boundaries of the information system segments;
ME type "B" - ME used on the logical boundary (perimeter) of the information system or between the logical boundaries of the information system segments;
ME of type "B" - ME used on the node (host) of the information system;
ME type "G" - ME used on a server serving sites, web services and web applications, or on the physical boundary of a segment of such servers (server). ME type "G" can have software or software and hardware execution and must provide control and filtering of information flows via the hypertext transfer protocol going to the web server and from the web server;
ME of the industrial network level (type "D") - ME used in the automated control system of technological or production processes.
