And that while I know a company who fired people who let collegues do a quick thing while they were still logged in under their own name.

This guy on http://www.darkreading.com/boards/me...?msg_id=134597 put it nicely:
You two have hit upon the very essence of the portable storage security problem-- the devices are meant to improve employee productivity, allowing employees to take work home with them. The guy who spilled all the data at Veterans Affairs was trying to be a good guy--he took his work home to do some extra, and then got his laptop stolen. The security people say shoot him, he exposed secure data. But if his laptop hadn't been stolen, he probably would have been praised for his extra effort. The technology is there to help the employees, and it seems that firing them, or denying them access to the technology, is contrary to its purpose. Yet, we can't just let these folks walk around with sensitive data, or allow them to introduce malware through curiousity about a found thumb drive. So what's the answer??
