Security of operating systems
Kuchař, Karel ; Komosný, Dan (referee) ; Člupek, Vlastimil (advisor)
This bachelor thesis is focused on security of operating systems, which is more and more important. At first, basics of security of operating systems will be covered, followed by describing elements, which help secure communication on internet. In the third chapter, there are discussed the most using operating systems in terms of security and mentioned their most common weaknesses. Following chapter talks about scenarios in which is defined how to properly set each part of the system, so it is secure; also, security applications that make operating system more secure are mentioned. In fifth chapter are above mentioned scenarios applied to virtual machines. To test chosen security settings were individual machines exposed to penetration test. Afterwards, the chosen security settings are evaluated and further steps are recommended. The goal of this thesis is to apprise with problems of security of operating systems and the importance of implementation of security measures.

Uncovering of rootkits and detection of spyware
Juras, Stanislav ; Pelka, Tomáš (referee) ; Polívka, Michal (advisor)
Bachelor’s thesis is about uncovering of rootkit and detection of spyware. It describes the basic types of known spyware and rootkits. Section dealing with spyware is especially about a description of each species. In case of rootkit the thesis is mainly about description of modes and the manner of their infection. There are also outlined attempts to use legal rootkit. In other case there are summarized the basic methods of rootkit and spyware detection, which are commonly used in various detection programs. The second part of thesis is practical implementation (the program) of one of the methods of spyware detection. The program is designed to be able to detect a simple pattern of spyware, which is stored in its database. The program uses the file signature detection. It contains also the graphical user interface, where is possible to choose a unit that user want to test.
