A Modular Cyber Range Platform for Smart Energy Systems
This paper presents a lightweight, modular Cyber Range platform built on FastAPI and QEMU/KVM that utilizes a YAML-based engine to automatically simulate realistic IT/OT environments, demonstrated through a multi-stage attack scenario on a smart city's photovoltaic plant to evaluate both technical vulnerabilities and human crisis response.

Imagine a world where the lights in your house, the traffic lights on your street, and the power grid keeping a military base running are all connected to the internet. This is the reality of "Smart Cities," where digital code controls physical things like electricity and water. But just like a house with a weak lock on the front door, these connected systems can be broken into. The scary part isn't just that hackers might steal your data; it's that they could shut off the power or mess with the machines that keep things running. To stop this, experts need a safe place to practice fighting these digital bad guys without actually turning off the real power grid. This is where a "Cyber Range" comes in. Think of it as a video game simulator for cybersecurity, but instead of shooting aliens, you are defending a city's power plant. However, most simulators are either too simple (only testing computer viruses) or too heavy and expensive to build. The big question is: Can we build a lightweight, flexible training ground that feels real enough to catch both the computer bugs and the human mistakes that happen when things go wrong?
This paper introduces a new, modular "Cyber Range" platform designed specifically for smart energy systems. The authors, a team from the University of Cyprus, built a system that acts like a digital Lego set for cybersecurity training. Instead of needing a massive, expensive supercomputer, their platform runs on standard hardware using a clever "recipe" written in a simple text format called YAML. This recipe tells the computer exactly how to build a fake network, complete with virtual machines that act like real computers, routers, and even industrial machines. The system is fast and flexible; it can spin up a complex scenario in minutes and shut it down just as quickly, making it easy for teachers and trainers to use.
The paper demonstrates this platform with a dramatic, fictional story set in a smart city. The scenario starts small: a hacker (the "Red Team") breaks into a home's Wi-Fi because the password is too weak. From there, they sneak into a solar power plant's control system and shut it down. But the attack doesn't stop there; it spreads like a virus through the city's network, eventually causing a major power outage at a nearby military base. The paper shows that their system can simulate this entire chain reaction, including the specific languages that industrial machines use to talk to each other (like Modbus/TCP and MQTT).
What makes this platform special is that it doesn't just test computers; it tests people too. The authors introduce a "Green Team" concept. While the "Red Team" attacks and the "Blue Team" defends, the Green Team represents the actual human operators—the engineers and managers who have to make decisions when the alarms start blaring. The system is designed to see how well these humans spot the problem, stay calm, and talk to each other under pressure. The paper suggests that this three-team approach provides a much more complete picture of how ready an organization really is to handle a crisis.
The authors ran simulations to prove their system works. They showed that their platform can successfully deploy these complex, multi-stage attacks and that the different teams can interact with the system as intended. They didn't claim to have solved all cybersecurity problems, but they demonstrated that their lightweight, modular design is a viable way to train people for the messy, real-world connection between digital hacks and physical consequences. The paper concludes by suggesting that future versions could get even smarter, perhaps using artificial intelligence to create new scenarios on the fly or connecting different training centers together to practice even bigger, cross-border attacks. For now, though, it stands as a promising new tool for keeping our smart cities safe.
