It's common knowledge that a security system is only as effective as its weakest point. You can install a reinforced steel door with a two-phase palm-print/retinal-scan entry to protect your home, but if you leave a first-floor window open, you're more vulnerable than your neighbor with a simple deadbolt. One of Nate's clients learned this lesson first hand with its e-commerce Web site. The operation didn't involve terribly sensitive data: there were no bank accounts, no Social Security numbers, nor even any credit card numbers. Pre-approved customers would simply sign in and place their orders. Accounts payable and fulfillment would take it from there.
