IoT needs segmentation
Good article.  As you clarify, you can't tell which IoT devices are weak - even the makers don't know.  The traditional endpoint tool chains don't work - scanning isn't effective, agents are not an option, and so on.  We have to think "3 piece", not "2 piece" - you can't trust either endpoint of the communication, so you have to put controls in between them.  Sadly,we're not that good at this, despite decades of effort.  Network segmentation is hard, but it's the only way to go, to limit the blast radius when things inevitably go wrong.
