In the last decades, reports and news about cyber attacks have showed up a turnover. Such exploits are making use of latest technology and exploiting new techniques and methodologies. Security specialists and researchers are making unique efforts to develop platforms that are capable of emulating threatening situations and allowing to learn how to counter them properly. The development of cyber ranges, simulated environments where vulnerable IT infrastructures are reproduced, mainly allow to improve the skills for people operating in the first line of defense, and of course to educate students in the cybersecurity field. To date, software virtualization techniques allow you to create simulated environments that are very faithful to the original ones, with deeply customizable network topologies and connected devices of all kinds.
