The world is increasingly awash in connected, "smart" devices. The phenomenon -- often termed the "Internet of Things" or IoT -- began with simple tools like Chromecast or personal digital assistants like Amazon's Alexa. Now it has grown to the point that nearly every device we use in our daily lives is, or is on the verge of being, electronically connected to all the others in a vast web of convenience. Innovations that seemed wildly futuristic just a few years ago are now part of our homes, our cities, and our supply chains. What people often fail to consider are the risks that come with all this interconnectedness.
