Forensic Malware Analysis
Král, Benjamin ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This master's thesis describes methodologies used in malware forensic analysis including methods used in static and dynamic analysis. Based on those methods a tool intended to be used by Computer Security Incident Response Teams (CSIRT) is designed to allow fast analysis and decisions regarding malware samples in security incident investigations. The design of this tool is thorougly described in the work along with the tool's requirements on which the tool design is based on. Based on the design a ForensIRT tool is implemented and then used to analyze a malware sample Cridex to demonstrate its capabilities. Finally the analysis results are compared to those of other comparable available malware forensics tools.

Threat management for CERT/CSIRT teams
Machálek, Jiří ; Peterka, Jiří (advisor) ; Lukeš, Dan (referee)
The increasing importance of the Internet as an integral part of contemporary society has stressed the need to formalize the process of response to security incidents that accompany it inseparably. Security teams of the CERT/CSIRT type are established at different levels for this purpose. These teams respond to reports from their constituency and cooperate with other teams. This thesis introduces the reader to the issues these teams deal with and analyzes their needs in resolving threats and problems related to DNS and its domains. Part of the work is an overview of the basic existing tools to support the work of CERT/CSIRT teams to solve problems with domains, the design of a tool Malicious Domain Manager and description of its implementation. The results of test run of this tool by CZ.NIC-CSIRT team show its contribution to security of DNS.

Linguistic Picture of Devil / Deuce in Czech Folk Tales
KOLÁŘOVÁ, Evelína
This bachelor thesis represents the ethnolinguistic field of linguistic study, with its subject matter being the genre of Czech folk tales. This genre is analysed based on the collection of Czech folk tales titled České pohádky (Drda, 1985). The analysis presents the view of the world in the perspective of a Czech native speaker - the linguistic picture of the deuce / devil in Czech folk tales, particularly based on Drda's work. The theoretical section of this thesis presents terms from the ethnolinguistic, sociological, and literary science fields of study. This section also establishes the methodology used for the purpose of this thesis in the context of linguistic research. In the practical section, the thesis presents an analysis in the form of a corpus of excerpts organised categorically by their semantic properties. This corpus serves as the starting point and allows the thesis to present tables of attributes organised by facets.
