Design of enterprise IEEE 802.11 wireless networks
Hlavatý, Josef ; Kubánková, Anna (referee) ; Novotný, Vít (advisor)
This bachelor thesis focus on wireless networks standardized as IEEE 802.11 and their use in wide wireless networks. Wireless transmissions and most known accessories of standard IEEE 802.11 and their functions are theoretically discussed in the first part of the bachelor thesis. Next, bachelor thesis takes care of architecture of vast wireless networks, their division into cells and centralized management of cells and individual AP. Further, security and authentication in wide wirreless networks is described. The second part of bachelor work is formed from detailed manual for execution of wide wireless networks, from which laboratory task is built for subject Network Architecture.

Protection of soft targets in the Czech Republic
KYSELA, Martin
This bachelor thesis entitled Protection of soft targets in the Czech Republic deals with current issues related to the security of soft targets in the Czech Republic. The goal of this thesis is to analyze the security of selected Christmas markets in December 2020. It is necessary to draw attention to the fact that all events which took place in the Czech Republic were affected by pandemic measures due to SARS-CoV-2 coronavirus infection throughout the whole year 2020, hitherto fairly unchanged to April 2021. These measures also applied to all mass public events that were directly dependent on the development of the pandemic at the time of the Christmas markets. The first aim of this thesis is to analyze security measures of selected public events - dec. 2020 Christmas markets in towns, namely: Praha, České Budějovice, Český Krumlov, Písek and Týn nad Vltavou. The selection procedure of cities mentioned above was carried out in the way that capital, regional and district cities were represented. Thus, the result is an evaluation of the degree of vulnerability of the Christmas market and their mutual comparison. The second aim of this thesis is to devise a leaflet that would clearly inform the public about the basic principles of behaviour in an attack on a soft target. Apart from the goals mentioned above, to investigate whether is the security/protection of soft targets at the selected public events in the Czech Republic is sufficient, statistical research has been implemented. The method of qualitative analysis of available literature is used to carry out this thesis. For the qualitative research, a selected number of Christmas markets was chosen concerning the situation at the time of the Christmas markets, the theoretical saturation was fulfilled. Based on the research results achieved in this thesis, there is a lot of room for improvement of existing security measures. Moreover, the protection of soft targets ought not to be belittled, given the current developments in both local and world politics. The results of this bachelor thesis can be used to obtain a comprehensive view of the issues addressed and the possible practical use of information obtained through research to improve the security policies in public events.
