IoT Security

I am getting a bit sick and tired of all this hand wringing about IoT security. All I see are generalizations, of which this article is all too typical.

It seems like all the security wonks assume that your "thing" has gigabytes of memory and runs linux. What about the huge number of thigns that run on 8 and 16 bit controllers (even the venerable 8051)?

So, I have a sensor sitting on a proprietary wireless link. The cost of simply encrypting that link could be huge just in the form of power consumption. So, someone messes with that sensor. Research data would be lost, but that is not like messing with a bank account! We really have to weigh the real (not imagined) benefits compared to the cost. I do not see anything, at alli, about this aspect.

So, someone messes with my toaster. What iws the possible outcome? A black piece of toast? Annoying, sure, but a lot less than to have my email hacked. Its also not like the power grid nor an oil pipeline. Don't we need to consider the just what might be compromised in the event of a security breach?

Isn't it about time to put aside these generalities and get real? HOW are we going to secure our 8 and 16 bit things? What do we need to do for practical threats? Isn't preveiontion of buffer over-run a big chunk of it, along with pass-words? What else? 

It is time to get CONCRETE with fewer of these broad generalities.
