Schneier's thought on the Internet of Things - Security

This is just a quote on Schneier's online article:
"On the Internet of Things, integrity and availability threats are much worse than confidentiality threats. It's one thing if your smart door lock can be eavesdropped upon to know who is home. It's another thing entirely if it can be hacked to allow a burglar to open the door -- or prevent you from opening your door. A hacker who can deny you control of your car, or take over control, is much more dangerous than one who can eavesdrop on your conversations or track your car's location"
