Re: Maybe we should rename it the Insecurity of Things
In the consumer industry, I'd say no one at this point because most of the outcomes of a hacked IoT device aren't that severe.The problem is, when security gets added on later once real problems arise, it means systems are less safe than if security had been built in from the start.
We might see more consumer-oriented action if the automotive industry gets deeply into IoT, i.e. as the car becomes more of a mobile hotspot and has apps that connect to third-party devices and systems, like reporting on your driving behavior to your insurance company, or ordering and paying in advance for a meal on at a turnpike rest stop. Once you add payments to the IoT mix, you get the security incentive.
However, I'd say medical device manufacturers and the healthcare industry have a significant stake in driving IoT security standards, if only for liability issues. Same for the use of IoT in industrial controls and manufacturing.
