One of my biggest challenges now is to accurately characterize the emerging threats of cybercrime and cyber espionage. Nobody wants to hear the bad news and the additional costs, but it’s only going to get worse. The trick for everyone is to determine the right level of response.

I'd argue that the best approach for the cyber criminal is social engineering: getting the unwary to click. OTOH, I see a greater awareness of "don't click if you don't know." Elderly relatives I assist with computers are now paranoid about clicking on anything!

I suppose the issue for the reader might be dealing with protecting the IP [intellectual property] surrounding drawing files? What about stealing license numbers from authorized users: is this an issue?
