Hi guys While I am studying network books at home, I would like to create a virtual test network in my computer where I can do all sort of networking practices and have a better understanding of cyber attacks, network security, etc. So, is it possible to create such environment with at least two users (more better) where one will act as the attacker and the other one as the target. I have only one computer with two internal and one external hdd. Can I use vmware or virtualbox for that? Thank you in advance.
