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.
So here’s what we did: We both created guest networks in our home and migrated all of our smart devices over to them. And we found out some very interesting things. 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.
Welcome to the inaugural Internet of Things Podcast with Stacey Higginbotham. It’s super exciting to be able to share the show with all of you, after these past few weeks of Gigaom closing its doors and us wondering about the fate of the show. This week my co-host Kevin Tofel and I have missed three weeks but didn’t miss a beat when it comes to reviewing the Staples Connect Home hub version 2, discussing the Apple Watch and Kevin’s earlier article on smart watches and their issues in general. In other news, look for more Kevin coverage at his new home on ZDnet.
After Kevin and I chat, I interviewed Brady Forrest, who is in charge of PCH’s Highway1 incubator on how to build hardware that won’t make consumers question why they bought it in the first place. Forrest, who has mentored startups such as Ringly and the company behind the Drop kitchen scale, has helped build companies whose products don’t suck. That’s why I asked him to join me for a chat. Listen in for some good advice and to hear me learn exactly how hard it is to develop hardware for the myriad platforms out there. I gained a new appreciation for the challenges companies are going through and learned something new. Listen up, and maybe if I get enough downloads, next week I’ll manage to get an intro and some music pulled together. Here’s hoping! In the meantime, listen below.
