THE INTERNET OF Things security crisis persists, as billions of inadequately secured webcams, refrigerators, and more flood homes around the world.
But IoT security researchers at Microsoft Research have their eye on an even larger problem: the billions of gadgets that already run on simple microcontrollers—small, low-power computers on a single chip—that will gradually gain connectivity over the years, exponentially expanding the internet of things population. And that connected electric toothbrush needs protection, too.
The challenge with IoT security so far has been the cost of implementing hardened features. It’s cheaper and faster to develop a product without spending time and resources on security. Devices rush off the line without adequate protections, often riddled with bugs, and rarely have a mechanism for manufacturers to distribute patches. An attacker who penetrates them can steal data.
