Corporations though are cowardly
I do think American culture, be it good or bad, has been a powerful influence. Our corporations however heed to lawyers who believe the phrase "risk management" is a synonym for "no".
What escapes attention here to an extent is the problem of Sony being hacked. I am sure someone inside Sony was involved in the news story that the hacking was incredibly sophisticated because it eluded their antivirus. If that is the measure of sophistication of attack, then there are millions of them. I have repaired dozens of boxes that off the shelf products couldn't find (there are better products out there, Malwarebytes is great at finding things normal AV can't, and it isn't even the best).
What amazed me is that Sony lacked perimeter protection. Sony should have seen 100TB of data flying out of server(s). Most places I have worked have that ability. I've seen warnings for 200Gb. Now maybe that is the sophistication, the perimeter was also compromised but I seriously doubt it. Just a guess, but they were a bit too lax on that front.
Which leads to the bigger problem, all our corporations are being hacked. Seriously, what's going on. I've attended security conferences and classes since the mid-90s. I've heard the stories about the NSA offering jobs to the best and brightest in math for work with computer systems. I theorize they've been working offensively. But I suspect they know the weak spots and could easily share them, but do not so they have their ways in. Believe me, I've heard more than a few people suggest the flaws that used to plague Microsoft were items the NSA loved. Maybe we need to get some first round picks on the defensive side of the ball. The NSA needs to turn its attention to helping American corporations and software makers. We are all very vulnerable. At the last class I was at, the instructor flat out said if the NSA or Chinese want in your server, there is nothing you can do to stop them. He said Russian gangs weren't far behind that. It is a problem we have to fix. Sony's other issues aside, the hacking itself is a huge concern.
