Introduction:
The landscape of hands-on cybersecurity training is undergoing a quiet revolution, moving away from costly, proprietary cloud platforms to accessible, open-source solutions that run on local hardware. At the forefront is StratocyberLab, a Docker-based cyber range that delivers a complete, self-contained training environment with an integrated AI assistant, enabling educators and students to deploy, attack, and defend complex networks without monthly subscriptions or external dependencies.
Learning Objectives:
- Deploy a fully functional, local cyber range using Docker and StratocyberLab on your own machine.
- Create, manage, and observe custom cybersecurity training scenarios and challenges.
- Integrate and utilize a local Large Language Model (LLM) as an intelligent assistant within the lab environment.
You Should Know:
1. The Foundation: It All Runs on Docker
StratocyberLab’s core architecture leverages Docker containers to create isolated, reproducible network environments. This containerized approach means every component—from the attacker’s machine to vulnerable services—runs in a dedicated container on shared virtual networks. The primary requirement is a system with Docker (version greater than 20.10) installed, a minimum of 2 GB of spare RAM, and 3 GB of disk space (with additional space needed for optional LLM models).
Step‑by‑step guide explaining what this does and how to use it.
The initial setup is designed for simplicity and speed, getting a basic lab running in minutes. From your terminal, execute the following commands to clone the repository and launch the environment:
git clone https://github.com/stratosphereips/stratocyberlab.git cd stratocyberlab docker compose up
This `docker compose` command builds and starts three core containers: the `hackerlab` (your attack box with SSH and core utilities), the `dashboard` (a web management interface), and optionally, the `ollama` container for AI assistance. Once the bootstrapping process completes, open your web browser and navigate to `http://127.0.0.1/`. You will be greeted by the lab dashboard, where you can start challenges, access a web-based SSH terminal, and configure settings.
2. Hands-On Hacking: Your First Challenge and the Web Dashboard
The web dashboard is the central control panel for the cyber range. Unlike passive learning from slides, effective cybersecurity education requires interactive, hands-on activities where students engage with real systems. StratocyberLab embodies this philosophy by providing a platform where learning happens “when things don’t work, when you make mistakes, and when you observe real effects.”
Step‑by‑step guide explaining what this does and how to use it.
After accessing the dashboard at `http://127.0.0.1`, your first task is to complete a “Hello World” challenge to verify your setup. This typically involves using the built-in WebSSH terminal to connect to the `hackerlab` container and performing a simple task, like finding a hidden flag. The dashboard allows you to start and stop specific challenge scenarios, submit flags for validation, and monitor your progress. This gamified approach—earning points and badges for completed challenges—significantly boosts student motivation and engagement.
- Building Your Own Cyber Battleground: Creating Custom Scenarios
The true power of StratocyberLab is not just in its pre-built labs but in its capability to function as a platform for creating your own scenarios. You can design custom networks, populate them with intentionally vulnerable machines and services, and script specific attack sequences. This transforms the tool from a simple lab suite into a foundational brick for an open-source cyber range tailored to your specific teaching or training objectives.
Step‑by‑step guide explaining what this does and how to use it.
Creating a custom scenario involves defining your environment in Docker Compose configuration files. You can specify new containers, their operating systems, installed services, and network connectivity. For example, you could build a scenario simulating a corporate network with a poorly secured WordPress server and a Windows client. The process involves:
1. Duplicating and modifying existing scenario definitions in the `scenarios/` directory.
2. Writing Dockerfiles to build custom vulnerable machine images.
3. Configuring network bridges in the `docker-compose.yml` file to segment traffic.
4. Scripting the deployment of flags or vulnerabilities within the containers.
- The AI Assistant: Integrating Ollama for Guided Learning
A standout feature of StratocyberLab is its built-in, optional AI assistant powered by a local LLM via Ollama. This provides a safeguard against learners becoming completely stuck, offering hints or clarifying concepts without giving away direct answers. It embodies the principle of “assisting beginners without doing the work for them,” promoting problem-solving skills over rote solution-following.
Step‑by‑step guide explaining what this does and how to use it.
The `ollama` container runs alongside the lab. From the web dashboard, you can control this service and choose from a variety of open-source LLM models to pull and run locally, such as `llama2` or mistral. The AI chat interface is integrated into the dashboard. When a student is stuck on a privilege escalation step, for instance, they could ask the AI, “What are common Linux privilege escalation techniques to check for?” The AI can provide general methodology prompts based on its training, guiding the student to discover tools like `linpeas` or to check for SUID binaries, without revealing the specific exploit path in the active lab.
5. Troubleshooting and Advanced Configuration
Running a complex Dockerized environment can occasionally run into issues. StratocyberLab’s documentation addresses common problems. A frequent issue is a `REMOTE HOST IDENTIFICATION` warning when SSH keys change after container recreation. Another is ensuring consistent functionality across different operating systems, particularly with line endings on Windows.
Step‑by‑step guide explaining what this does and how to use it.
For common issues, use these verified commands:
- Forcing a Clean Rebuild: If you’ve pulled updates and the lab behaves unexpectedly, rebuild the containers from scratch:
docker compose up --build --force-recreate
- Fixing SSH Host Key Warnings: When connecting to the rebuilt `hackerlab` container via SSH, bypass the host key check:
ssh -o UserKnownHostsFile=/dev/null student@<container_ip>
- Windows-Specific Git Configuration: To avoid CRLF line ending issues on Windows, configure Git globally and re-clone the repository:
git config --global core.autocrlf false git config --global core.eol lf
- From Classroom to Professional Training: Scaling the Concept
StratocyberLab is part of a larger, vital movement toward open-source cyber ranges. Platforms like the KYPO Cyber Range Platform, released as open-source software, demonstrate the significant impact these tools can have on university education and professional training across Europe and beyond. Similarly, initiatives like Norway’s Open Cyber Range Project aim to develop cybersecurity thinking in both the private sector and education by providing cost-effective environments for testing and validation.
Step‑by‑step guide explaining what this does and how to use it.
Implementing a cyber range for an organization or larger class involves planning for scale. While StratocyberLab excels on a single machine, the concepts extend to server deployments. For a training session with dozens of participants, you could deploy multiple instances on a powerful server, with each participant or team connecting to a dedicated instance. The architecture mirrors that of larger, cloud-based ranges like the open-source AWS CyberRange blueprint, but retains the benefit of local control and zero ongoing cloud costs. The key is ensuring sufficient hardware resources—CPU, RAM, and storage—to handle the concurrent load of multiple running lab environments.
What Undercode Say:
- Democratization of Cyber Training: Tools like StratocyberLab are fundamentally lowering the barrier to entry for high-quality, practical cybersecurity education. By eliminating cloud fees and platform dependencies, they empower individual learners, small training companies, and educational institutions with limited budgets.
- The Power of “Real” Observation: The platform’s emphasis on observing real network traffic and unedited effects of attacks provides irreplaceable context. This moves beyond the “sanitized” version of events often presented in theoretical courses and aligns with the critical need for hands-on skills development highlighted by modern cybersecurity pedagogy.
The shift toward localized, open-source cyber ranges represents more than a technical trend; it is a pedagogical necessity. As cyber threats evolve with increasing complexity, the industry’s skills gap widens. Expensive, walled-garden training solutions cannot scale to meet the global demand for competent practitioners. StratocyberLab and its philosophical cousins signal a future where the foundational tools for building cyber expertise are freely available, customizable, and rooted in the authentic experience of experimentation and failure. This model doesn’t just train individuals; it fosters communities of practice where scenarios and knowledge are shared openly, accelerating the overall resilience of the digital ecosystem. The educator’s role thus evolves from content deliverer to environment architect and guide, a change that promises to produce a generation of professionals better prepared for the realities of defending dynamic networks.
Prediction:
Within the next three to five years, localized, open-source cyber ranges will become the standard entry point for cybersecurity education globally. We will see a proliferation of shared, community-developed scenario libraries and increased integration of specialized AI agents for personalized coaching and adaptive difficulty. This will force commercial training platform vendors to drastically rethink their value proposition, shifting from providing basic lab access to offering advanced analytics, certification pathways, and complex simulated environments that integrate with these local platforms, creating a hybrid model of accessible core training and premium advanced services.
