Hey guys I am in a competition where we have to set up 2 sites that have to exchange with a transaction site. Each will be on its own VM in a massive server to simulate different servers. One of the servers is running lubuntu, Windows server, and ubuntu.
During the competition a green team will try to use the services, they represent general users and we are given points based on usability. A red team will then come on and try to hack into the servers and steal info causing us to lose points.
I need some advice or a place to look for info about cyber security or network infrastructure.
