I used to work in a vaulted research lab where any use of the USB ports on your machine and/or using a non-virus scanned CD would leave an alert to be audited by the security office. This wasn't even secret data, just in proximity of machines that might have contained some but policies are org-wide. This anecdote isn't really Google related, but just to say that big enterprises are tracking in ways you might not think about every day.
