Comprehensive cyber arena; the next generation cyber range

Abstract

The cyber domain and all the interdependencies between networked systems form an extremely complex ensemble. Incidents in the cyber domain may have an abundance effect on the physical domain. For example, a cyber attack or an intrusion against an electricity system may affect the performance of healthcare system as well. For organisation's cyber resilience, know-how is the key resource. Cyber security training and exercises have an extremely important role for achieving the required level of know-how in the cyber domain. The old military based-proverb You Fight Like You Train is relevant in the cyber domain. Traditionally, the platform for cyber security training and exercises is called cyber range. Because of the accelerating digitalisation and more complex totality of the cyber domain, also the infrastructure for the cyber security training and exercises is required to be more and more complex. In this paper, the concept of cyber arena, next generation cyber range, is discussed.
