I'm trying to bring awareness around the need for [authentication with encryption](http://www.windowsecurity.com/articles/Authentication-Forgotten-Predominant.html) by using software to alert and report on failed [MAC](http://en.wikipedia.org/wiki/Message_authentication_code) verification attempts, and sharing the results with middle management.

I'm not a cryptographer, but I see the value in a proper implementation. Ideally I'd like to create a report that says X attacks were prevented.

Is this a valid idea, or is it overly simplistic? If not, where should I start in implementing it? (Low level AES, PGP, etc?)
