Fixing IoT. The persistent rumor is that an IoT botnet is being used. So everything is calling for regulations to secure IoT devices. This is extraordinarily bad. First of all, most of the devices are made in China and shipped to countries not in the United States, so there’s little effect our regulations can have. Except they would essentially kill the Kickstarter community coming up with innovative IoT devices. Only very large corporations can afford the regulatory burden involved. Moreover, it’s unclear what “security” means. There no real bug/vulnerability being exploited here other than default passwords — something even the US government has at times refused to recognize as a security “vulnerability”.
Fixing IoT #2. People have come up with many ways default passwords might be solved, such as having a sticker on the device with a randomly generated password. Getting the firmware to match a printed sticker during manufacturing is a hard, costly problem. I mean, they do it all the time for other reasons, but it starts to become a burden for cheaper device. But in any event, the correct solution is connecting via Bluetooth. That seems to be the most popular solution these days from Wimo to Echo. Most of the popular WiFi chips come with Bluetooth, so it’s really no burden for make devices this way.
It’s not IoT. The Mirai botnet primarily infected DVRs connected to security cameras. In other words, it didn’t infect baby monitors or other IoT devices insider your home, which are protected by your home firewall anyway. Instead, Mirai infected things that were outside in the world that needed their own IP address.
