Secure Coding Guidelines for Java
Jalakšová, Michaela ; Malinka, Kamil (referee) ; Tamaškovič, Marek (advisor)
Java je populárny programovací jazyk, ktorý je široko používaný v rôznych aplikáciách. Java však nie je výnimkou, pokiaľ ide o zraniteľnosť voči útokom, ktoré hľadajú bezpečnostné chyby v kóde. Cieľom tejto práce je zvýšiť povedomie o zraniteľnostiach programovania v Jave a vyvinúť vzdelávací nástroj, ktorý pomôže programátorom naučiť sa písať bezpečnejší kód. Cieľom tohto nástroja je poskytnúť programátorom Javy informácie o postupoch bezpečného kódovania a prostredie, kde sa môžu naučiť základy bezpečného programovania. Táto práca tiež poskytuje riešenie niektorých bežnejších zraniteľností v Jave.

Accessibility of Transport Nodes from the Perspective of People with Disabilities
Navrátil, Jan ; Pavlovský, Tomáš (referee) ; Tichý, Jan (advisor)
The bachelor thesis entitled Accessibility of Transport Nodes from the Perspective of People with Disabilities deals with selected most important transport nodes in Havlíčkův Brod. The first part of the thesis deals with the theory that describes the individual elements that are within the framework of safe and barrier-free use of roads. The second part of the thesis is practical, where suggestions for improving the selected routes are made. Accessibility of transport nodes from the perspective of people with disabilities is a document that serves as a concept to develop safety and accessibility of transport nodes in cities. This work can also serve as a basis for investors who want to build or repair places that are not easily accessible and potentially dangerous for people with disabilities. The work is created with the intention that people with disabilities can safely complete the routine journeys they use every day. The adaptations are designed for all types of disabled people, which include those with physical, visual and hearing impairments. The town of Havlíčkův Brod was chosen for this work due to the fact that there is a large transport hub in the form of a train and bus station, which are complemented by public transport stops. The routes connecting the individual objects are analysed in terms of barrier-free use and their current condition.

A Service for Querying Aliases of Malicious Software
Julina, Tomáš ; Regéciová, Dominika (referee) ; Zobal, Lukáš (advisor)
The main goal of this bachelor's thesis is to design and develop service, which would deal with the problem of existence of malware aliases by providing mapping of each alias to specific family. The specific family would be set as canonical in advance. This thesis also presents several ways of obtaining data automatically for such mapping. The created service is meant to help malware researchers in their research. It can also be used in existing services, that currently don't take malware aliases into account, which could have caused some duplicity in their data.

Performance Comparison of Libraries for Homomorphic Cryptography
Babjak, Pavol ; Perešíni, Martin (referee) ; Malinka, Kamil (advisor)
Kryptografia je neoddeliteľnou súčasťou oblasti počítačovej bezpečnosti. Pri využívaní bežných kryptografických metód a operáciách nad nimi však nie sú jednotlivé dáta nijako chránené proti neoprávnenému prístupu alebo krádeži tretími stranami. Homomorfná kryp- tografia rieši presne daný problém, teda dokáže pracovať s dátami, ktorých obsah nepozná a súčasne dokáže vykonávať jednotlivé operácie nad nimi. Cieľom práce je nájsť jednoduché prípady užitia pre praktické využitie homomorfnej kryptografie, implementovať ich pomo- cou jednotlivých prostredí ktoré pre svoje fungovanie využívajú túto technológiu a zmerať ich výkonnosť a ďalšie dôležité aspekty pri výbere najvýhodnejšieho prostredia a šifrovacej schémy pre danú praktickú aplikáciu.

Information System Assessment and Proposal of ICT Modification
Jagošová, Táňa ; Novák, Lukáš (referee) ; Koch, Miloš (advisor)
This bachelor thesis deals with the analysis of the current state of the information system of a selected pharmacy and the subsequent proposal for its improvement. The theoretical part of the thesis characterizes important concepts for better understanding of the following parts of the thesis. The analytical part evaluates the current state of the information system in the pharmacy with the help of selected analyses. The results of the analyses serve as a basis for the design part, where solutions to the system's deficiencies are presented and then the costs and benefits of the proposed solution are shown.

Acceleration of DTLS Protocol in Linux Kernel
Krenželok, František ; Lichtner, Ondrej (referee) ; Grégr, Matěj (advisor)
Tato práce poskytuje náhled do protokolu DTLS1.3, se zaměřením na klíčovou funkcionalitu důležitou pro implementaci v rámci kryptografických knihoven a integraci na úrovni systémového jádra. Hlavní výsledky zahrnují implementaci DTLS1.3 v rámci knihovny GnuTLS a rozšíření tohoto protokolu do linuxového jadra v rámci existujicího modulu TLS. Práce nadále hodnotí užitečnost tohoto systémového modulu ve spojení s nově vznikajícími technologiemi, jako je BPF, a projekty jako je ktls-util.

Technological stage of the rough superstructure of an library in Veselí nad Moravou
Vančo, Lenny ; Průcha, Aleš (referee) ; Šlanhof, Jiří (advisor)
The aim of my bachelor's thesis is to develop a technological project for the technological stage of the rough upper structure. For this work, I chose the construction of a new library in the town of Veselí nad Moravou. The project was created by Ing. Katarína Božková as part of her diploma thesis at the Faculty of Civil Engineering at the Brno University of Technology. It is a public amenity building. The library also includes a bookstore and a café. The technological prescription is prepared for reinforced concrete monolithic ceilings. Additionally, I will address the logistics of transportation routes, the bill of quantities, the design of the construction site setup, the selection of machinery, work safety, the inspection and testing plan, and the schedule plan.
