Software for control and management of home automation
Michálek, Jakub ; Blažek, Petr (referee) ; Musil, Petr (advisor)
This master thesis describes the development of an application for control and management of smart sockets at home. The first part describes the software that was used in creating this application. Specifically, the Qt application platform and the SQLite relational database system. The second part describes the structure and function of this application. The next part describes the application used to test the functionality of the created application and the designed communication protocol. The last part of the work describes the testing and evaluation of the created application.

Industrial automation protocols simulation
Surový, Roman ; Pospíšil, Ondřej (referee) ; Blažek, Petr (advisor)
The aim of this work is to implement a workplace that will simulate the network infrastructure of industrial automation protocols. In this work we focus on and perform analysis of industrial protocols ModBus, Profibus, Profinet, EtherCAT, CANopen. Furthermore, the network infrastructure with PLC with selected protocols will be operated. The output of the work will be a workplace that will be able to simulate real communication of two selected protocols between two and more devices. Another part of the work will be the simulation of three types of equipment occurring in an industrial environment.

Honeypot for wireless communication protocols of IEEE 802.11 family
Řezáč, Michal ; Blažek, Petr (referee) ; Fujdiak, Radek (advisor)
Objective of this master thesis solves possible way of WiFi Honeypot realisation, which is constructed to detecet malicious network activity and attacks in radio environment that uses a set of IEEE 802.11 protocols. A specific configuration was created on the mITX format motherboard and contains scripts and software for data collection, analysis and its evaluation. Based on information and knowledge about specific network attacks it is possible to identify data traffic leading to anomalies and detect possible network attack. The final device was tested in real use for long-term data collection and evaluation of network activity in the given location. This fulfills the main goal of this work, which is implementation of WiFi Honeypot with support for IEEE 802.11 protocols and with possible deployment for real use.

CIP industrial protocol simulation
Molent, Michal ; Musil, Petr (referee) ; Blažek, Petr (advisor)
The thesis is about industrial automatic CIP protocol, which belongs to SCADA systems. The first part is focused on basic principles of CIP protocol and on analysis of two protocols (EtherNET/IP and DeviceNet), which are based on CIP protocol. The second part deals with designing scenarios for a simulation. The simulation of one-way communication, two-way communication with help of reads from the console and two-way real time communication between Raspberries PI 3B+. The third part deals with a realization of the simulation, a start-up and a function of predefined scenarios and graphic interface. The fourth part deals with analysis network communication in situations, which occur during a protocol EtherNet/IP simulation.

IEC 61850 simulation environment
Rusz, Lukáš ; Fujdiak, Radek (referee) ; Blažek, Petr (advisor)
The work deals with communication protocols of the IEC 61850 standard. The protocols GOOSE (Generic Object Oriented Substation Events), SMV (Sampled Measured Values) and MMS (Manufacturing Message Specification) are described. The protocols are used to create a simulation network, which is described in this work. The simulation network is created in the OMNeT ++, program installed in the Ubuntu virtual environment.

IEC 61850 industrial communication simulator
Srp, Jakub ; Pospíšil, Ondřej (referee) ; Blažek, Petr (advisor)
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.

Vulnerabilities assessment for industrial protocols
Zahradník, Jiří ; Fujdiak, Radek (referee) ; Blažek, Petr (advisor)
Thesis deals with testing of selected vulnerabilities from the IEC 61850 standard and following design of mitigation measures for selected vulnerabilities. Author simulated vulnerabilities of the GOOSE protocol, NTP attack and attack ona MMS client. Those attacks were GOOSE stNum, GOOSE semantic, GOOSE test bit,GOOSE replay, GOOSE flood, NTP spoofing and MMS password capture. Attacks on protocols GOOSE and MMS were successful, attack on NTP was only partially successful since the device confirmed receiving spoofed time, however it did not change it’s inner clock. Author then designed possible mitigation measures. Tool for automatic testing of selected vulnerabilities, parser for the GOOSE protocol and lightweight multiplatform parser for configuration files were created as well.The outcome of this thesis allows the implementation of lager scale tool for penetration testing of industrial networks as well as it allows implementation of discussed mitigation measures.

Simulation of communication part of modern industrial networks
Beneš, Pavel ; Blažek, Petr (referee) ; Fujdiak, Radek (advisor)
The thesis is focused on simulating of protocols from standard IEC 61850 in simulation tool OMNeT++. The theoretical part in the thesis deals with description of the field of operating technologies, supervisory control and data acquisition and protocols Tase-2/ICCP, IEC 61850, IEC 60870-5-104, DNP 3 and DLMS/COSEM. Next part deals with parameters influencing connection and description of simulation tools NS2/NS3, OPNET and OMNeT++. In the practical part there is created a network containing protocols from the standard IEC 61850 in the simulation program OMNeT++. Then in the network a end to end delay and packet loss with increasing traffic is measured.

Cyber-security in systems of publish-subscribe type
Detko, Adam ; Blažek, Petr (referee) ; Pokorný, Jiří (advisor)
This thesis deals with data distribution service and is divided into three parts. The first part of this thesis focuses on theoretical knowledge of data distribution service. This section gradually introduces the model used in data distribution service, quality of service and the RTPS protocol, which was specially developed for the needs of data distribution service. The most comprehensive part of the theoretical part deals with security in data distribution service. At the end of the first part of this thesis, selected impelementations of data distribution service are introduced. The second part of this thesis deals with practical use of data distribution service, while OpenDDS implementation is chosen for the practical part. This part initially deals with the design of basic communication scenarios, followed by the design of complex communication scenarios. In the next chapters, within the practical part, the thesis is focused on verifyng security of the data distribution service selected implementation, design of security incidents and their subsequent simulation. Content of the final part of this thesis is the introduction of a tool designed for this thesis, which is used to implement selected types of attacks.
