AUTOMATIC FIREWALL Russian patent published in 2016 - IPC H04L12/723 H04L12/935 

FIELD: safety.

SUBSTANCE: invention relates to information security of computer networks and, in particular, defines characteristics of setting up firewalls used for filtering network traffic and protection of computer network nodes from unauthorised access. Said technical result is achieved by following design features and traffic filtering algorithm. Automatic firewall is a combination of hardware and software that includes at least two network interfaces, allows filtering of transit traffic without setting its interfaces, network addresses, thus includes a processor that implements an algorithm layered filtering network traffic based on analysis of transit direction traffic as measured by inlet and outlet supplies of network interfaces to shared computer network segments, as well as analysis of telecommunication traffic transit protocol states.

EFFECT: technical result achieved in present invention is enabling segmentation of computer networks without having to reconfigure network nodes, reconfigure firewall and form filter rules.
