Get ready for Bluetooth mesh

With the recent problems of DDoS's from simplistic devices on the Internet of Things, this worries me. Who will ensure that the devices are paired only with things they are supposed to be paired with? Who will prevent a rogue agent from connecting to your mesh and overwhelming it?

I come from an age when everything was cool, fun, exciting, and everyone played nice. Email didn't have to be secured, messages could be sent directly to terminals, and commands could be executed without worrying that people would strip your machine, take your details, empty your bank account, and turn it into a spam relay.

Where are the security details?
