On automatic network environment cloning for facilitating cybersecurity training and testing

Cyber attacks are happening worldwide on a daily basis. It results in a great need to have a system that can construct a practical network environment, in terms of both network functions and background traffic flows, for the purposes of security tool assessment and cyber range creation. The concept of "cloning" traditionally is to create an identical copy of a single entity, such as a machine or a software. In this paper, we propose an extension of this concept through building a system that can clone a production environment, both in terms of network functions and legitimate traffic flows. We also present our current progress in building the first prototype of the system.
