ACTING: A Platform for Cyber Ranges Federation
This paper introduces the ACTING platform, which addresses the need for interoperable cyber defense training by presenting the EDL-FG language for standardized scenario description, implementing automated performance evaluation and scoring mechanisms, and enabling multi-domain exercises across federated cyber ranges.

Imagine you are trying to teach a group of firefighters how to handle a massive, complex disaster. In the past, you might have had one fire station with a small practice building. But real disasters happen everywhere at once: a fire in a skyscraper, a gas leak in a factory, and a traffic jam on a highway, all affecting each other.
To train for this, you need to connect many different training grounds together so they act like one giant, realistic world. This is exactly what the ACTING paper describes. It presents a new "digital platform" that connects different cybersecurity training centers (called Cyber Ranges) so they can work together seamlessly.
Here is a breakdown of how it works, using simple analogies:
1. The Problem: Too Many Different Playgrounds
Currently, different organizations have their own "Cyber Ranges" (virtual playgrounds where they simulate cyber-attacks). The problem is that they all speak different "languages" and use different rules. One range might be great at simulating a bank hack, while another is great at simulating a power grid failure, but they can't easily talk to each other to create a scenario where a bank hack causes a power grid failure.
2. The Solution: The ACTING Platform
The authors built a "super-manager" platform called ACTING. Think of it not as a playground itself, but as the central control tower and marketplace that connects all the different playgrounds.
- The Marketplace (Service Catalogue): Imagine a travel booking site, but instead of hotels, you book "cyber-defense training exercises." Organizations can list what they offer (like a specific type of attack simulation), and others can browse and book them.
- The Universal Translator (EDL-FG): This is the paper's biggest invention. It's a special language called Exercise Description Language.
- The Analogy: Imagine trying to build a Lego castle with instructions written in English, while your friend has instructions in Japanese. You can't build it together. EDL-FG is like a universal translator that turns all those different instructions into a single, clear blueprint that every computer system can understand. It describes both the "hardware" (the virtual computers and networks) and the "story" (the cyber-attack events and how people should react).
- Because of this, a scenario designed in one country can be instantly deployed and run across training centers in five different countries without needing to rewrite the code.
3. The Coach: Automated Scoring and Awareness
In a real war game, you need a referee to tell you if you did a good job. In the past, this required a human watching every screen. ACTING automates this.
- The "Smart Referee" (Performance Evaluation): The system automatically watches what the trainees do. Did they fix the firewall in time? Did they type the right commands?
- The Analogy: It's like a video game that instantly grades your score. If you are writing a report, the system doesn't just check if you spelled words right; it uses AI to check if your sentence structure makes sense and if your logic is clear, giving you a detailed scorecard immediately.
- The "Big Picture" View (Situational Awareness): The system collects data from all the connected training centers to show a "big picture" dashboard. It helps instructors see how different teams are doing and where the whole group is struggling, rather than just looking at one isolated room.
4. The Actors: User Simulators
To make the training realistic, you need "fake people" to act like normal users or hackers.
- The platform includes User Simulators. These are digital actors that behave like:
- Blue Users: Normal employees clicking emails and browsing the web.
- Red Users: Hackers trying to break in.
- Grey Users: People doing neutral things.
- The instructors can program these actors to act out specific scripts, making the training feel chaotic and real, just like a real cyber-attack.
5. The Real-World Tests (The Scenarios)
The paper shows three examples of what this platform can do, proving it works for complex, mixed situations:
- Scenario 1: A combined attack on a military headquarters, land forces, and navy systems. It simulates how a simple USB drive trick can spread across different branches of the military.
- Scenario 2: A mix of space and sea. It shows how messing with satellite signals (space) can lead to a ransomware attack on ships (sea), proving the system can handle "cross-domain" disasters.
- Scenario 3: A military base data theft. It focuses on spotting a sneaky intruder trying to steal classified info and following the proper chain of command to stop them.
Summary
In short, the ACTING paper introduces a platform that acts as a universal connector and referee for cybersecurity training. It uses a new "universal language" (EDL-FG) to let different training centers work together, automatically grades how well students perform, and creates realistic, multi-layered scenarios that mix civilian and military challenges. It turns isolated practice drills into a coordinated, global simulation.
