How to deal with WPE PRO?

Question

Traffic analysis

We need a way in which the traffic would not be listened to. What should be the encryption/cryptography? What protection against packet spoofing?
in which case the fact of sniffing is detected (the sender of the packets finds out that it is not only the addressee who hawks him, unless of course there is software for such an analysis of the axis driver and the card hardware)?
The use of switches (switch, switch-hub) and their competent configuration is already protection against eavesdropping. How to do it?
There are few AntiSniff and PromiScan programs.
The game Panzar has protection against WPE PRO.
