This thesis is focused on IEC 61850 communication protocols SMV, GOOSE and MMS and their implementation in SCADA systems. There is a simulator, run on Raspberry Pi, that generates data according to IEC 61850 and transmits the data using protocols in question. The simulation consist of various virtual devices e.g. surge protection, undervoltage protection, circuit breaker, disconnector, HMI. The MMS protocol is used for station control. Simulation can be user-defined from textual configuration file.

Capturing cyber-threats of industrial systems
Dobrík, Andrej ; Pospíšil, Ondřej (referee) ; Fujdiak, Radek (advisor)
S vedomím že kybernetické útoky stoja korporácie každoročne miliardy, počínajúc neoprávnenými útokmi, distribuovanými útokmi odmietnutia služieb (DDOS) až po vírusy a počítačové červy atď., prichádza problém s nástrojmi, ktoré majú k dispozícii správcovia systému. Táto diplomová práca sa venuje skúmaniu jedného z takýchto nástrojov, Honeypot. Presnejšie, Honeypot zariadeniam pre priemyselné riadiace systémy. Od historicky počiatočných implementácií takýchto systémov, cez analýzu súčasných riešení až po vytvorenie nového riešenia Honeypot, s vysokou mierou interakcie a následným nasadením na nový virtuálny súkromný server, po ktorom nasleduje analýza narušení, ktoré sa vyskytnú počas obdobia nasadenia.
