There is a very interesting story in a UnixAdminTalk discussion group that talks about the entire Quebec Healthcare system becoming infected with a virus. The virus had a denial of service attack component that effectively killed several hospital network connectivity. The blog says that some hospitals were down for three days and reverted to paper to order tests etc.
Now if there ever was a case for having layered authentication security strategy, I'd say this was it. They didn't and the result was a provincial crisis.
