I've been saying since SOX, HIPPA, and GLB hit hard that we were going to eventually see "SOX like" legislation for privatly held businesses/small businesses. Remember you heard it here first!
I see in the future the companies who have managed to skate by with lax security having to step up to the plate. The banks in this article have a darn good argument. It is usually the merchants who end up losing information. And if they're not publicly traded, we may never know about it.

Pretty much every company holds either credit card info, bank account numbers, or social security numbers in some form or fashion. If this is compromised, it could mean an easier route into a more protected entity, like a bank perhaps. The way this is starting is usually how the government gets involved and lays down the law. The banks are saying they're not to blame, the merchants say they're not because they have to meet PCI standards, and the credit card companies say obviously blame the banks because they are more concerned with GLB than they are PCI. Those of you making the move to security, get ready. I see another tub of opportunity in the near future as some of the stiff security regulations that government agencies, public companies, banks and the medical world have to try and meet (and suffer the embarrassment of public disclosure) makes it's way down to "mom and pop" shops (mine included).
The next 5 years will be very interesting in the security world.
