Analýza síťové komunikace IoT bran

Modern IoT gateways are mainly developed by private companies behind closed doors. This results in a closed ecosystem, where only a tiny amount of information about traffic is available to the public. Therefore, to gain knowledge regarding the operation and communication of such gateways, it is necessary to examine and analyse network traffic flowing to and from such gateways.This thesis's primary goal is to capture and process network traffic data of multiple commercially available gateways intended for home use, analyse their communication behaviour, compare the results to other studies carried out in this area, and discuss possible attacks on used gateways, based on gathered data. Communication data were obtained by deploying a controlled environment and analysed using Zeek, together with Wireshark software. Collected communication data can be further used by researchers in the areas of networking or security.
