Internet of Things news and analysis: smart home, industrial internet of things, enterprise internet of things, and more. Joins co-hosts Stacey Higginbotham and Kevin Tofel as they dissect the week's latest IoT news. Stacey Higginbotham has covered technology since 2001. In my years covering tech I became more fascinated by the stuff we were able to do on vast computing networks and ever speedier mobile and wireline broadband networks. Finally all of the elements of the technology I’ve covered in more than a decade have culminated in this moment and we’re creating the internet of things. No matter what you call it, we’re at a pivotal moment in the evolution of human creativity, business creation and productivity gains. We could see the gains we make in these next few years help us conserve resources and let us lead safer and healthier lives or we could open the door to a dystopian society where our every thought is monitored and our every utterance is effectively for sale. I hope to explore all of these issues, the people who will make it possible and the devices that will lead us there in the IoT Podcast. I hope you will join me.

Episode 248: Should I put my IoT devices on a guest network?
This week’s Internet of Things Podcast is a bit different from our typical format. Instead of discussing a range of topics and sharing a guest interview, we’re tackling the question we get so often from our listeners who are rightfully concerned about their home network security with smart devices installed: Should all of these webcams, smart locks, thermostats, and other devices be segmented to a guest network?
On the surface, that sounds like a smart idea. The main reason is that any compromised smart devices won’t be able to infect computers and other things on your primary network. A secondary reason is to limit access to your smart home when guests are over.

For starters, we didn’t lose access to any of our devices through this setup, which is good. However, we also found out that the reverse situation is a bad one. When on our guest networks with devices on the regular network, we still had access to many of them unexpectedly, which is bad.
Our takeaway is that if you want to put your smart home devices on a guest network, that’s fine but it may not add much more security. In particular, if your smart device credentials are stolen, as was the case with recent “hacks” of the Ring and Nest systems, this setup won’t really help you. We’re thinking that using a network monitoring system such as a Firewalla is a better solution. And better yet would be installing a router that supports VLANs, or Virtual LANs, for your smart home devices. Tune in and let us know what you think or if you have additional related network concerns or solutions.
