Securing the Internet of Things

As cybersecurity experts love to say, the “S” in “IoT” stands for security… meaning there is none. I’ve seen estimates that say there were almost 30 billion IoT devices on the internet in 2022. I have dozens of them on my home network alone. Each of these devices contains at least one computer, which is running potentially hackable software. And because these devices have internet connections, they are vulnerable to cyber attacks from anywhere on the planet. Today I’ll ask Bill Niefert from Corellium how IoT devices differ from regular computers, how secure they are, what the risks are of insecure smart devices, and how we can make them better.
