Security assessment for industrial protocols
Priščák, Jaroslav ; Blažek, Petr (oponent) ; Fujdiak, Radek (vedoucí práce)
This bachelor thesis is focused on security verification of selected protocols used in ICS/SCADA systems. The theoretical part explains the basic principles of the division and management of SCADA systems. Consequently on their communication using protocols (MODBUS, DNP 3, IEC 60870-5-104 and IEC 61850) and their capabilities. In the next chapter, the thesis deals with the analysis of these protocols in terms of security and design methods for their verification. The selected protocols were DNP3 and IEC 60870-5-104, which deal with the work of next parts. Virtualized network, which was simulated using the selected communication protocol DNP3 and IEC 60870-5-104 was created. Subsequently, the security of the protocols was tested using the developed tools and the Kali Linux virtual machine. In the last chapter, the thesis deals with mitigation measures on these created attacks.

Interaktivní webové aplikace pro podporu výuky 3D počítačové grafiky
Priščák, Jaroslav ; Mokrý, Ondřej (oponent) ; Rajmic, Pavel (vedoucí práce)
Používanie interaktívnych webových aplikácií má potenciál výrazne zlepšiť výučbu 3D počítačovej grafiky. Využitím pohodlia a dostupnosti webu môžu tieto aplikácie poskytnúť študentom pútavejšiu a interaktívnejšiu výučbu. Táto práca sa zaoberá vývojom takýchto aplikácií s cieľom pomôcť pochopiť základy nutné pre výpočty, ako sú normálové vektory a~dotykové roviny. Ďalej práca popisuje Phongov osvetľovací model, parametre prostredia a~materiálu, ktoré vplývajú na výsledný svetelný odraz. Následne popisuje jednotlivé modely tieňovania ako konštantné, Gouraudovo a Phongovo, kde popisuje jednotlivé výhody a nevýhody, rozdiely náročnosti výpočtov pri určovaní farby fragmentu a jednotlivých pixelov. Zároveň vysvetľuje kód, na ktorom sú tieto aplety vytvorené.
