IoT Traffic Generation and Detection of Security Incidents

The main purpose of my bachelor thesis is to design and create operation generating system of IoT networks, creating security incidents and their detection. First part describes basic principles of IoT networks, SCADA systems and communication protocols IEC 60870-5-104 and DLMS/COSEM. Subsequently there are described industrial tools emulating operation of SCADA systems using investigated protocols. The next section describes the security of these systems, along with the risks they face. Based on this information, a tool was designed and implemented to simulate various types of attacks on SCADA systems and track their reactions. The last part of the work is devoted to the possibilities of detecting di erent types of attacks and how to protect the networks from them
