Smart meters are increasingly a part of everyday households. These smart meters allow remote reading of the energy but also remote disconnection of the point of consumption from the energy supply. As these devices are part of the critical infrastructure of the country, the security of these devices needs to be tested and the relevant personnel trained. We would like to contribute to the scientific community by bringing practical experience from smart meter testing into the Cyber Range virtual environment. In this environment, professionals working with smart meters can be trained and smart meter safety tests can be performed. This paper presents common smart meter vulnerabilities and their demonstration in the Cyber Range environment. The article includes a sample description of scenario for testing so anyone can try it.

This paper deals with the use of cyber range in education to teach cybersecurity. Particular attention is paid exclusively to open-source solutions, as such solutions are available to the general public, which is essential in raising awareness of cyber defense. First,the available open-source cyber ranges are described, their advantages and disadvantages. Subsequently, it presents our selected solution, the procedure of implementation in the Brno University of Technology laboratory, our use in our study programe and stress testing of selected cyber range. Last but not least, it provides a unique guide to designing and building own open-source cyber range LAB from scratch.
