Development and Deployment of a Platform for Efficient Data Collection and Visualization in Opportunistic Sensor Networks
Chovancová, Emília ; Miklánek, Štěpán (oponent) ; Musil, Petr (vedoucí práce)
Opportunistic sensors represent an interesting alternative to obtain valuable information and data that saves resources ecologically and economically. The meteorological gauges and sensors that are described within the scope of this thesis, also belong to this category. In the future, they will be used in comparison with different microwave link. The aim of the thesis was to create technical documentation for the respective gauges, describing their technical characteristics, data flow and proposing security improvements of the infrastructure. Another objective was to create a web application to enable optimized real-time data visualization and thus inform users about the current weather conditions within the FEKT campus.

Analysis of possible threats in old OS Linux version
Chovancová, Emília ; Dejdar, Petr (oponent) ; Tomašov, Adrián (vedoucí práce)
The bachelor thesis is focused on the security aspect of an older version of a Linux based machine. The document is split into a theoretical part which contains a description of what operating system, kernel, UNIX, GNU/LINUX and Linux OS are in general. Then the description proceeds to explanation of active and passive attacks such as replay, masquarade, denial of service, man in the middle or listening and analysing the network. Afterwards it continues with description of potentially vulnerable spots that are common on operating systems. With the help provided from scanning software, especially Nmap and Lynis, the document proceeds to the practical part which contains various types of successful and unsuccesfful attacks such as password recovery, denial of service, spectre, brute force of a password and cross-site scripting. The last part covers the protection against succesfull attacks and adds a little bit more of additional protection in general in a form of an ansible script.
