Internet of Patches

This is a good recommendation:

As a sysadmin, I've been saying fuckno to things like Smart TVs and fridges. I do that game professionally, and I know what it takes to keep a fleet of software up to date. It ain't easy. Keeping firmware updated in things like... non-Nest internet attached thermostats (yes, they exist), the PC embedded in the fridge, the hub that runs your smart lighting, the firmware in your BluRay player, internet-attached talking dog toys... It's hard. And it only takes one for Evil People to get inside your crunchy exterior and chow down on everything else.

You can probably trust a company like Schlage to treat their software like a security-critical component of a network. You probably can't say the same about the internet-attached talking dog toy, even though they're likely on the same subnet. The same subnet as all of your iPads, MacBooks, and phones. Segmenting the network makes it harder for evil coming in on the, shall we say, vendor supported side from the more routine evils faced by general web-browsing.

Not that segmenting is easy to do, unfortunately.
