  abstract = {<p style="margin-left:20.15pt;">The current cybersecurity landscape is conducive to the enhancement of the traditional cyber-exercising paradigm and instruments. Considering the complex nature of the cyberattacks and their cascading impact, moving away from purely technical or entirely decision-making exercises is becoming paramount for realistic exercising of emergency response. Complex cyber-hybrid scenarios, exercising effective collaboration at the technical, operational, and higher decision-making levels, are increasingly employed to prepare to face emerging hybrid threats. Such scenarios simulate seemingly independent incidents in different locations, businesses, or systems that may quickly escalate to a sectoral or a national crisis. Unfortunately, such diverse scenarios remain inaccessible due to the lack of proper simulation infrastructure and expertise to adapt them to various contexts. The current contribution presents the authors{\textquoteright} experience in designing a Composite Cyber Range, following a Systems-of-Systems approach for the dynamic activation or incorporation of playgrounds and on-the-run integration of custom-made emulation or overlay ranges to support an {\textquotedblleft}exercise-as-a-service{\textquotedblright} model for the provision of adequate and accessible cyber-hybrid mechanisms for crisis response training and preparation.</p>},
