A Knowledge Repository maintaining interoperability between multiple Cyber Ranges

Ensuring Cyber security professionals are well-prepared to handle real-world cyber threats requires continuous training and access to diverse and up-to-date threat scenarios. Within this context, Cyber Ranges play a crucial role through the provision of controlled environments for Cyber Security training and simulations. However, a significant challenge identified in the literature is the lack of interoperability between Cyber Ranges, which hinders the exchange of exercises and resources. This paper showcases the utilization of a Knowledge Repository with a unified data model to address the interoperability challenge among Cyber Ranges, enabling seamless data exchange and integration. To the best of our knowledge, this approach has not been provided in any other existing solution. The paper further explores the challenges of implementation and the potential impact of this solution on cross-sector data sharing and regulatory compliance.
