Security assessment for industrial protocols
Priščák, Jaroslav ; Blažek, Petr (referee) ; Fujdiak, Radek (advisor)
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.

Interactive web applications supporting education of 3D graphics
Priščák, Jaroslav ; Mokrý, Ondřej (referee) ; Rajmic, Pavel (advisor)
The use of interactive web applications has the potential to significantly improve the teaching of 3D computer graphics. By taking advantage of the convenience and accessibility of the web, these applications can provide students with more engaging and interactive learning. This thesis explores the development of such applications to help understand the fundamentals required for calculations such as normal vectors and tangent planes. Further, the thesis describes Phong's illumination model, the environmental and material parameters that affect the resulting light reflection. It then describes the different shading models such as flat, Gouraud and Phong shading models, describing the various advantages and disadvantages, the differences in computational complexity in determining the color of a fragment and individual pixels. It also explains the code on which these applets are built.
