And if anyone has some software that could help me test my security that would be great (maybe some debuggers that can change variables during run-time).
Game description, as requested: I't a mix between a MMO RPG and an RTS game. That means that players actively contribute to the world building. The basic idea is that the client tells the server what he is doin (pressing a key, typing something into chat) and the the server broadcasts that message to everyone else. I know what I have to do now, thanks!
