Cyberspace is the fifth domain of warfare after air, soil, water, and space, where the battlefield is not only limited by physical boundaries but also by virtual ones. Critical infrastructures such as energy, water, nuclear, defense, chemical and healthcare sectors are lucrative targets to the state sponsored attackers at the time of geo-political tensions. Cyber armies of the nations are now adopting “Offense is new Defense” strategy to remain one step ahead of attackers. This has led to cyber arm race which is more dynamic, and subject to change drastically with the introduction of new and complex technologies. In such environment, training and learning cyber-warfare strategies is resource intensive and time consuming. It brings challenges to develop essential cyber security skills and remain up to date with the fast moving industry requirements. To understand how security functions for a target system, it requires a simulation of the target environment repeatedly for different scenarios. These scenarios consist of sets of technologies, network architectures, operating systems, protocols, and services. Installing and configuring such scenarios are complex and time consuming process for a security practitioner. This brings us to derive a methodology to simulate customized, modular, repeatable, a network of system by leveraging recent advancements in virtualization technologies and DevOps principles. In this article, the concept has been validated with common enterprise network scenarios having heterogeneous systems automated over virtual platform. Result offers an easy-to-go approach for building cyberspace scenarios that can be utilized to learn and practice cyber operation strategies.
