How many net-connected doodads are secure? The answer: none of them. Every device is woefully unprotected from various attacks, and to make matters worse, many of them might contain confidential information ripe for the picking. And if all that weren’t sufficiently disconcerting, the vendors of such miscellany aren’t particularly motivated to make them secure – even if they knew how to do it properly. Which they don’t. Nevertheless, we blindly forge ahead, building out the Internet of Things (IoT), as though the security issues will somehow resolve themselves. Just how worried should we be?
