In fact, had to have SPENT MONEY to make it worse. Someone, someplace, put it into a less secure state "to save money" or "for business reasons." What we're seeing is that their cost/benefit analysis was wrong; it didn't save as much as they thought (because they did it wrong!) or, if it recouped enough on the investment, then any additional security expense comes out of that profit/benefit's margin. Let me belabor that point a bit: security is often seen as a bill that gets presented; a cost of doing business. What they don't understand is that the bill is just interest coming due for when they cut some corners years ago. A break-in or disaster is that interest, compounded. This is one reason I am (obviously) highly skeptical of many business justifications. They omit to take hidden costs into account and then try to shift/blame someone else for them later. It's very easy to see something as a profitable and desirable activity as long as you only look at the upside. mjr. -- Marcus J.
