ECHO Federated Cyber Range: Towards Next-Generation Scalable Cyber Ranges

Cyber ranges are valuable assets for cybersecurity training and education, advanced prototype development, and
certification testing. To address the limitations of individual cyber ranges in terms of their capabilities and capacities to
simulate complex realities and multi-sector dependencies, federated cyber ranges are emerging. This work presents the
ECHO Federated Cyber Range, a marketplace for cyber range services, that establishes a mechanism by which the independent cyber range capabilities can be interconnected and accessed via a convenient portal for configuration and management. Its features and architecture are described in detail, along with the design,validation, and deployment of a training scenario.
