Remotely Accessible Exercise Environment for Intrusion Detection/Defense Exercises Based on Virtual Machine Networks

Abstract

Network security exercises carried out in laboratories have limitations of time and place. Students cannot exercise during their free time and outside the campus. Furthermore, teaching attack skills to students raises the issue of maintaining ethical standards. We have developed LiNeS (Linux Network Simulator) that generates networks for network administration exercises by using virtual machines; such a network is called a virtual machine network. In this study, we realize a virtual machine network in which attacks are generated automatically in a remotely accessible exercise environment by using LiNeS. Our system can resolve the abovementioned problems because students can completely focus on intrusion detection/defense via PCs connected to the Internet.
