About this interactive

What you are doing: sorting what an adversary in the middle did by the part of the CIA triad it harmed. An adversary in the middle sits between two parties, so every message passes through it, and it chooses what to do with each one. Reading or copying the traffic breaks confidentiality. Changing it on the way, in either direction, breaks integrity. Dropping, holding back or delaying it breaks availability. How to use it: ask what happened to the message. Was it seen, changed, or stopped?
