System Preferences.
Looking at Rich's employer's site, ironkey.com, I suspect the idea is
to provide the security even if the machine does not have this
preference set.
For instance, if you plug a secure, encrypted USB key into a public-
access Mac, to which you may not have admin access in order to change
the preference setting. You don't want some malware running on such a
machine to be able to snoop the password that you enter to access the
contents of the key.
