Considering this technology’s high economic impact, we should prioritize its security. We can expect that protecting these devices will require a lot of time and money.
3. The first IoT device was a Coca-Cola vending machine at Carnegie Mellon University.
We can trace back IoT devices to the early 80s. David Nichols invented a Coke machine that could report its inventory back to a network.
It’s funny how that happened, though:
Nichols’ office at Carnegie Mellon University was some distance from the vending machine. He would often walk to find it empty or recently refilled with warm cans. But with this invention, he could track the status of his favorite beverage remotely.
4. Today, Smart TVs are the most common IoT device in the US.
