Specific anomaly detection methods in wireless communication networks
Holasová, Eva ; Blažek, Petr (referee) ; Fujdiak, Radek (advisor)
The diploma thesis is focuses on technologies and security of the wireless networks in standard IEEE 802.11, describes the most used standards, definition of physical layer, MAC layer and specific technologies for wireless networks. The diploma thesis is focused on description of selected security protocols, their technologies as well as weaknesses. Also, in the thesis, there are described security threats and vectors of attacks towards wireless networks 802.11. Selected threats were simulated in established experimental network, for these threats were designed detection methods. For testing and implementing designed detection methods, IDS system Zeek is used together with network scripts written in programming language Python. In the end there were trained and tested models of machine learning both supervised and unsupervised machine learning.

Conversion between Formats for Sharing of Network Security Alerts
Eis, Pavel ; Wrona, Jan (referee) ; Žádník, Martin (advisor)
There are many platforms and systems designed for sharing cyber security incidents and events, which often use different security formats. This way it gets harder or even not possible to share security incidents and events between organizations, which are using these platforms. Solution of this problem may be creation of converters, which are capable of converting used security formats between each other. This work solves conversion between security formats IDEA, MISP and STIX. In the process of conversion, it is important to care about conversion flow, to prevent information loss or different category of event assignment, than which it was originally represented by. If the conversion is accurate enough, it can be easier achieved more precise and broader analysis of cyber security incidents.
