Security verification tool for industrial and energy equipments
Sagindykova, Anel ; Kuchař, Karel (referee) ; Blažek, Petr (advisor)
Cílem této práce je analyzovat různé vyhledávače a vybrat ty nejvhodnější pro vytvoření nástroje k testování průmyslových a energetických zařízení z pohledu bezpečnosti. Bylo provedeno porovnání mezi Shodan, ZoomEye, Nexpose, Censys a BinaryEdge. Tyto vyhledávače byly porovnávány podle různých kritérií, například výkonnosti a jejich dalších veřejně dostupných informací. Jako nejvhodnější byly vybrány Shodan a ZoomEye a pomocí těchto vyhledavačů byla vytvořena webová aplikace. Tato aplikace je schopna načítat výsledky vyhledávání ze serverů pomocí jejich rozhraní API a je schopna je ukládat do databáze. Součástí práce je popis průmyslových a energetických protokolů, sítí a jejich bezpečnostních prvků. V rámci práce byl také popis několika nejznámějších útoků na tyto sítě. Posledním cílem práce je provést testování a evaluaci realizovaného nástroje na minimálně dvou zařízeních.

Traffic generator of industrial protocols
Šnajdr, Václav ; Blažek, Petr (referee) ; Martinásek, Zdeněk (advisor)
This bachelor thesis deals with generating data traffic of industrial SCADA protocols and their implementation into JMeter tool. This tool can be expanded with plugins. Three protocols DNP3, IEC61850 and IEC60870-5 are described in the theoretical part. The practical part is devoted to the design and implementation of the DNP3 protocol module and partly to the design of the IEC61850 protocol. The DNP3 module has been functionally tested. There is also an attempt to obtain the TASE.2 library.

Gathering information about industrial equipment using a search engine
Danko, Krištof ; Fujdiak, Radek (referee) ; Pospíšil, Ondřej (advisor)
The work is focused on operating technologies, specificaly on the security of PLC (programmable logic controller), and obtaining information using device search engines. The types and parts of industrial networks, which are the main segment of operational technologies, and the search engines such as Shodan, Censy, BinaryEdge, and Zoomeye are described. These search engines are compared based on available information and industry protocols Siemens S7, Modbus, Ethernet / IP, and DNP3. In addition to comparing search engines, this work aims to create an application that can download results from the Shodan search engine via the Shodan API and store them in a database. Another point of work is the connection of own PLC, to determine the time of PLC appearing in search engines.

Appropriate strategy for security incident detection in industrial networks
Kuchař, Karel ; Blažek, Petr (referee) ; Fujdiak, Radek (advisor)
This diploma thesis is focused on problematics of the industrial networks and offered security by the industrial protocols. The goal of this thesis is to create specific methods for detection of security incidents. This thesis is mainly focused on protocols Modbus/TCP and DNP3. In the theoretical part, the industrial protocols are described, there are defined vectors of attacks and is described security of each protocol. The practical part is focused on the description and simulation of security incidents. Based on the data gathered from the simulations, there are identified threats by the introduced detection methods. These methods are using for detecting the security incident an abnormality in the network traffic by created formulas or machine learning. Designed methods are implemented to IDS (Intrusion Detection System) of the system Zeek. With the designed methods, it is possible to detect selected security incidents in the destination workstation.

Emulation of Attacks on SCADA/ICS Communication
Grofčík, Peter ; Grégr, Matěj (referee) ; Matoušek, Petr (advisor)
The goal of this master's thesis is to emulate suitable network attacks on the control communication of ICS/SCADA systems with a subsequent design and implementation that can detect them. The first part of the work consists of categorization and acquaintance with individual types of attacks on industrial networks. Using classified datasets combined with a research of available datasets, in the next chapter I describe the selection of suitable attacks, which are at least indirectly related to control communication and are also feasible on virtual devices that are communicating using the IEC104 protocol, which I chose for my work. I then perform the selected attacks and record their progress in a set of PCAP files. Those files form the input for the next part that concerns anomaly detection using statistical methods.

Simulator of SCADA protocols
Bohačík, Antonín ; Mlýnek, Petr (referee) ; Blažek, Petr (advisor)
This work is focused on creation of fully functional communication generator of IEC 60870-5-104 protocol. The theoretical part explains in detail the basic principles, properties and possibilities of communication standards DNP3, IEC 60870 and IEC 61850. The next part is focused on the analysis of communication and implementation of this communication in the PQ MEg44PAN device. The last part deals with the configuration of Raspberry Pi 3 devices and the communication emulation of the IEC 60870-5-104 protocol. All programs were written and tested using the Clion development environment.

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.

An Analysis of Smart Grid Communication Protocols
Sobotka, Lukáš ; Grégr, Matěj (referee) ; Ryšavý, Ondřej (advisor)
This work deals security of SCADA industry systems which are used in energetic networks. It describes architecture of those systems and also analyze in details two communication protocols -- DNP3 and IEC 60870-5-104. Next part is devoted to the analysis of anomaly and security threats which can be happen in SCADA systems. The main goal of this work is design and implementation of system which will be able to detect some of threats or anomalies. Also is necessary to propose simulation environment for testing.
