That's exactly the problem with IoT-- there's no standard, out-of-box solutions right now. Try to google for "IoT security": you will find a bunch of (mostly proprietary) competing solutions with no clear leaders among them. See my other comment on this thread, were I've provided HTTPS as an example for IoT ecosystem. I'm an experienced embedded developer and most often, when it comes to security, I still have resort back to "invent my own" security solution, because I can't find anything that fits project needs.
