Network probe module for industrial protocol analysis
Srovnal, Dominik ; Pospíšil, Ondřej (referee) ; Blažek, Petr (advisor)
Industrial networks are often the target of attacks, which need to be adequately responded to. Therefore, it is necessary to prevent these attacks from the outset through protection and prevention. Such protection is provided by intrusion detection and prevention systems, which are capable of preventing unwanted intrusions, based on those modules. As attacks become more and more sophisticated, it is essential that these modules are continuously developed and got proposed in new, safer measures. The theoretical part describes industrial protocols (IEC 61850, IEC 60870, Ethernet/IP and S7). The practical part focuses on the creation of a module for the analysis of the industrial protocol S7. Furthermore, the paper describes possible attacks on the S7 protocol and proposes rules for detecting these attacks using the Suricata module.

Software Support for PLC Automation Systems
Kříž, Karel ; Ševcovic, Jiří (referee) ; Chmelař, Petr (advisor)
This thesis mainly deals with the study of communication protocols between process control systems of company Siemens and their superstructural systems (SCADA/HMI) the Ethernet interface. This is a management systems, which are mainly used by Aucon s.r.o. in practice. It also deals with OPC servers, and their use with client applications. Emphasis is placed on the theoretical analysis of certain types of inter-processcommunication in Windows. From the simple one to the model COM, which is the basis of the OPC technology. Practical part realize implementation of a simple programming interface, providing communications with equipment Siemens Simatic S7. This is realized by C++ with using WinSock2 a IPHlpApi libraries. This interface can be used at programming client application.
