I like the author's self-identified attitude that "threats of 'cyberwarfare' waged through the public internet are the stuff of Hollywood schlock and patriotic pulp fiction". I think in general he's right about this particular threat. The conflict between security and usefulness is always vexing. The Stuxnet seems to have been propagated by a desire to make monitoring of data center equipment very easy. But somehow the application was corrupted. More attention to security could, perhaps, have avoided it, but how many hoops are busy Data Center managers going to jump through?
