When I'm explaining risks for process networks to non-IT folks I don't
talk about a "someone" hacking into the network and blowing it up or
doing other malicious things. I tell them about the network I watched
go down when only two of five hundred machines got infected with a new
virus that the up-to-date AV software didn't know about. The plant
blowing up is Hollywood. The plant going down for hours or days...now
that's a loss of productivity they can feel in their pants, especially
in today's job market.
