Title text:
It's important for devices to have internet connectivity so the manufacturer can patch remote exploits.
Transcript:
[A store salesman, Hairy, is showing Cueball a dehumidifier, with a "SALE" label on it. Several other unidentified devices, possibly other dehumidifier models, are shown in the store as well.]
Salesman: This dehumidifier model features built-in WiFi for remote updates.
Cueball: Great! That will be really useful if they discover a new kind of water.Source: https://xkcd.com/3109/
FYI I learned About VLANs that it is in no way „locked down“. I can spoof the MAC address of a known device from a specific VLAN and I’m in that VLAN. Yes your devices can’t reach the internet/other devices by default but it won’t stop a bad actor.
and this is why I have a completely separate physical network for my IOT stuff.
I'm aware you need a firewall (I used sonicwall professionally) vlans are for segmentation
Isn't that what 802.1x is for? If you really want to lock down your network, there are options.
Well. The segmentation is to avoid security holes from Rogue third party devices. If you can access my pc vlan that only exists on my wired pcconnection, then you have indeed broken in to my domain. Letting the things that doesn't give a shit about security have their own network is just sanity/sanitary.
