Objective of this master thesis solves possible way of WiFi Honeypot realisation, which is constructed to detecet malicious network activity and attacks in radio environment that uses a set of IEEE 802.11 protocols. A specific configuration was created on the mITX format motherboard and contains scripts and software for data collection, analysis and its evaluation. Based on information and knowledge about specific network attacks it is possible to identify data traffic leading to anomalies and detect possible network attack. The final device was tested in real use for long-term data collection and evaluation of network activity in the given location. This fulfills the main goal of this work, which is implementation of WiFi Honeypot with support for IEEE 802.11 protocols and with possible deployment for real use.
