Topological analysis of computer network threats
Řeháková, Jaroslava Antea ; Jirovský, Václav (advisor) ; Trčka, Martin (referee)
To understand overall vulnerability to network attack, one must consider attacker exploits not just in isolation, but also in combination. That is, one must analyze how low-level vulnerabilities can be combined to achieve high-level attack goals. In this project, we describe a tool that implements a topological approach to network vulnerability analysis. Out TAU Model includes modeling of network security conditions and attack techniques with use of preconditions/postconditions dependencies. An important part of TAU Model is The Graph of Dependencies that is used for creating exploit sequences leading to specifics attack goals. This representation enables highly scalable methods of vulnerability analysis, such as discovering security flaws of given network configuration. An important subject of this project is discussion about complexity and stopping of TAU Model computation. We also mention future extension possibilities and technical challenges.

Financial analysis
Šebová, Magdalena ; Mikovcová, Hana (advisor) ; Řeháková, Jaroslava (referee)
The aim of this bachelor thesis is to assess financial health of the HOCHTIEF CZ a.s. company. First part of the thesis is focused on the methods used in the analysis of the company. Second part shortly introduces the company itself. In the third part there is accomplished financial analysis of the company at the hand of the selected ratios which are mentioned in the theoretical part.
