Abstract: With the advent of technologies associated with the internet of things solutions and devices it became necessary to solve the security of these infrastructures that could be easily defeated and are often involved in standard network infrastructure which also includes other critical data. This study deals with the firewall creation on Linux distributions on the Raspberry Pi 3 device. Effective internal network protecting consists creating some firewall implementation for allowing or denying some configured connections or separation of a part of the network to the separated network (demilitarized zone). Firewall implementation may also be used for protecting of individual IoT device based on Linux implementation. In this study, there are described solutions for creating and configuring firewall based on Linux distribution Raspbian Jessie Lite which is primarily intended for Raspberry Pi 3 equipment.
