The Internet of Things is a problem because there is no security infrastructure for them.
HP decided to change this, starting with their printers. They are leveraging technology from Red Balloon Security that takes the problem of security out of the hands of users and into the world of devices.
The biggest security risk in the IoT area is routers/networking. Get a virus or other hack in the network and watch problems spread. And if the industry continues to leave responsibility for security to the users, frankly, not much will happen (most users don't see the larger security threats).
It's great to see device manufacturers taking a stand to protect their devices and the network - and move security out of the hands of users. It's really not their job.
I can't wait to see what HP does next!
