Cyber Range for Wireless Security Training

Cybersecurity professionals require hands-on training environments to hone their skills. Traditional wireless security training programs often focus on generic network labs, neglecting specific Wi-Fi protocols.

Developing a Custom-Built Cyber Range

Researchers at the Norwegian University of Science and Technology and the University of the Aegean have addressed this gap by developing a custom-built Wi-Fi cyber range for security training.

Emulating Wi-Fi Networks

According to the researchers, “the proposed cyber range uses software simulation to emulate Wi-Fi networks, leveraging the Linux kernel module mac80211_hwsim to simulate 802.11 radios.” This approach allows for the isolation of each emulated access point and client within a single virtual host, mimicking the behavior of separate devices.

User-Space Services

The platform includes user-space services such as hostapd, wpa_supplicant, dnsmasq, and FreeRADIUS to manage the simulated network, providing a realistic representation of enterprise-grade setups.

Supporting Practical Skills Development

The platform includes a suite of tools for wireless discovery and deauthentication testing, packet inspection, and WPA implementation fuzzing. These tools, developed by the research team, cover a range of scenarios, including rogue access points, deauthentication attacks, and handshake weaknesses in WPA2 and WPA3.

Instructor Tools

Instructors can create customized exercises using a web interface, choosing from prebuilt topology templates or describing their desired scenario in plain language. The platform utilizes a locally hosted Large Language Model (LLM) to convert the description into a structured scenario definition.

Limitations and Future Plans

The researchers acknowledge the limitations of the platform, noting that software emulation cannot replicate radio interference, propagation effects, or hardware quirks. However, they believe that the platform can be a valuable resource for cybersecurity professionals seeking to develop their skills in wireless security, particularly in areas such as 802.11 protocol analysis and WPA implementation fuzzing.

Conclusion

The open-source release of the Wi-Fi cyber range offers a low-cost alternative for building wireless security skills, and its modular design makes it accessible to both educational institutions and corporate training teams. As Wi-Fi continues to play a critical role in corporate networks, the need for effective wireless security training is likely to grow, making this platform an important contribution to the field.
