Cyber security tester of elements used in industrial networks and energy industry
Březina, Jiří ; Mlýnek, Petr (referee) ; Lieskovan, Tomáš (advisor)
This thesis deals with the issue of security analysis of DLMS/COSEM protocol and exploitation of these vulnerabilities in real Smart Grid environment. Thesis starts with a description of power grids in the past and present, introducing the environment of modern power grids and the smart grid elements used in it this power grids to reader. This is followed by a detailed discussion of the communication protocols that operate in these networks, beginning from the older and more industrially based Modbus protocol to the DLMS/COSEM protocol which is most used today and his various components and security. The most common current models of link vulnerability attacks are also summarized in the paper. The thesis aims to implement a tester that tests the security of smart grid elements, mainly on the vulnerabilities described in the thesis. The tester primarily focuses on the vulnerability called replay attack and evaluating the execution of this attack in a laboratory environment.

Cyber security tester of elements used in industrial networks and energy industry
Březina, Jiří ; Mlýnek, Petr (referee) ; Lieskovan, Tomáš (advisor)
The following is a detailed discussion of the communication protocols that work in these networks, from the older and more industrially based Modbus protocol, through the IEC 60870 protocol suite, to the most commonly used protocol today, DLMS/COSEM. The paper also summarizes the most common current attack patterns on DLMS/COSEM protocol vulnerabilities. The thesis aims to implement a tester that tests the security of smart grid elements mainly on the vulnerabilities described in the thesis. The tester primarily focuses on the vulnerabilities of overwhelm and replay attacks and evaluating the execution of these attacks in a laboratory environment.
