Module for Network Policy Monitoring in Flow Data
Piecek, Adam ; Kučera, Jan (referee) ; Wrona, Jan (advisor)
The aim of this master's thesis is to design a language through which it would be possible to monitor a stream of network flows in order to detect network policy violations in the local network. An analysis of the languages used in the data stream management systems and an analysis of tasks submitted by the potential administrator were both carried out. The analysis specified resulted in the language design which represents pipelining consisting of filtering and aggregation. These operations can be clearly defined and managed within security rules. The result of this thesis also results in the Policer modul being integrated in the NEMEA system, which is able to apply the main commands of the proposed language. Finally, the module meets the requirements of the specified tasks and may be used for further development in the area of monitoring network policies.
Enhancement of Probabilistic Methods for Password Cracking
Lištiak, Filip ; Polčák, Libor (referee) ; Hranický, Radek (advisor)
This thesis describes passwords cracking using probabilistic context-free grammars, specifically PCFG Cracker tool. The aim of the thesis is to design and implement enhancements to this tool, which reduce the size of output dictionaries while maintaining acceptable success rate. This work also solves critical parts in the tool that slow down the overall duration of the program. Another goal of the thesis is to analyze and implement targeted attack dictionaries that increase the scope and success rate of generated passwords.
Technological Solution of a Gross Superstructure of the Apartment Building in Complex Ponava City, Brno
Handlíř, Jan ; Hejl, Martin (referee) ; Mohapl, Martin (advisor)
The subject of the bachelor thesis is tegnological construction project of a gross superstructure of the apartment building in a complex Ponava city in Brno. The building is seven-storey and has a basement. Vertical walls are partly from masonry and partly from reinforced concreate. The ceilings are from reinforced concrete and the building has a flat roof. The thesis includes a technical report, technological methods of construction, technical report of a site equipment, machine draft report, inspection and test plan, work safety and comparing different materials of vertical walls.
Risk Management in Mechanical Engineering
Weiserová, Gabriela ; Predný, Patrik (referee) ; Doskočil, Radek (advisor)
This thesis deals with the issue of risk management of SCIOX Box machinery. The theoretical part provides an introduction to the basic concepts and procedures in the area of risk management, whose implementation into practice then deals with the analytical part. In the analytical part, the risks of selected machinery are analyzed and evaluated in accordance with the ČSN EN ISO 12100: 2011 norm together with other relevant norms. In the final part there are suggestions and recommendations for making the risk management process more effective in the selected company, which is the manufacturer of machinery - ELEDUS s.r.o.
Risk Assessment and Minimization in OSH in Construction Companies
Albrecht, Daniel ; Beneš, Martin (referee) ; Schüllerová, Barbora (advisor)
This diploma thesis focuses on the evaluation and minimization of risks in the area of occupational health and safety (OSH), specifically on risks in the construction industry. The analysis of the current state evaluates the issue of current OSH from the European and national point of view, defines terms and contains basic principles of safe work with construction machines. The main task of this work is to analyze the risk associated with the performed activity on a model example and propose suitable measures for their minimization including financial evaluation.
Design of new laboratory exercises with gigabit passive optical network
Chlápek, Jan ; Škorpil, Vladislav (referee) ; Horváth, Tomáš (advisor)
The diploma thesis is focused on design of new laboratory exercises on the topic of gigabit passive optical networks. The theoretical analysis is devoted to acquaintance with basic problematics of PON and analysis of individual PON standards. Special attention, besides GPON, XG-PON and EPON standards, is devoted to security issues in PON. The goal of practical section of the thesis is the design of four laboratory exercises. Two exercises are focused on configuring GPON and XG-PON networks in a console environment with the help of exemplary console commands. The goal of the third exercise is to hook up and configure an EPON network using web configuration interface. The fourth exercise is designed for a realization of DoS attack against a fully functioning laboratory GPON network. The objective is to jam the upstream communication bandwidth with laser transmission causing a desynchronization between active network elements.

Risk analysis of operated horizontal milling machine
Mergeščíková, Lenka ; Rozehnalová, Jana (referee) ; Blecha, Petr (advisor)
This bachelor thesis concerns about the risk analysis of the operated console horizontal milling machine produced in 1963. The thesis contains an overview of the valid legislation of the European Union and the Czech Republic concerning occupational safety and health. Subsequently, a review of the current harmonized standards and standards valid in the year of construction is conducted. Another part of the thesis is the identification of hazards and the proposal of preventive measures to reduce risks. In conclusion, acquired knowledge is summarized.
