I see two practical issues with network segmentation: 1. It breaks broadcast/multicast, e.g. for your phone discovering your chromecast. A number of IOT devices need to be on the same network as the devices from which you want to use them. 2. It’s way too complicated for novice users to set up, so it cannot be vital for making IOT devices secure. Personally, I like to keep all my devices (whether IOT or not) patched (ideally because they’re auto-updating). That way, if a lightbulb gets hacked, it can’t get to my backup drive either. That being said, I do think there’s some value in throttling bandwidth for IOT devices. It’d need to happen automatically (which makes it hard), but would nicely prevent DDOS attacks.
