He uses an example of the Amazon Echo which is "always listening" and raises the question of how welcome it would be in an office where confidential and highly sensitive conversations are frequent. "How many things are showing up at the office this week that are an always-on conduit to your network from some external third party you really shouldn't be trusting? Watches, streaming media widgets, phones, tablets and a whole host of other things are likely making their way into the office right now. You probably have a BYOD policy, but do you have an IoT policy? BYOD policies are meant to address your mobile handsets, tablets and personal laptops, but who's addressing all the other gadgetry?"
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
