Bill asked: “I got one of those D-Link routers that look like a spaceship. It’s got 3 channels. Just installed a Linksys range extender upstairs. How secure are these systems? Or what is the best, most secure system to automate things like turning lights on and off in a house?”
Bill, these systems are as strong as the encryption you’re using. Ideally you want to be using WPA 2 + AES encryption, and you’re better off having WPS or Wireless Protected Setup disabled, since WPS has been an attack vector used against WPA networks for a while.
There are still some security vulnerabilities when you use those settings, but they generally require that you’re already connected to the network, so they’re not a big threat to smaller networks or homes.
As far as secure IoT systems, well… we have bad news for you.
As far as secure IoT systems, well… we have bad news for you. HP did a study in 2014 that showed that 70% of IoT devices didn’t even bother with encrypted networks, that 60% used insecure web interfaces and did not use encryption when downloading updates.
Frankly, when it comes to lights, that’s not a huge concern, but IoT systems also include smart locks, smart garage door openers, and more. If security is a top concern for you, you may want to wait a little longer, this lack of proper security is a recognized issue that is being worked on. Your best bet may be to wait for an updated lineup of smart hubs that takes encryption more seriously than the current ones.
