Secure your smart home network: segmentation, updates and passwords
Every connected device is a computer on your network.
What to do
- Change default passwords and use unique ones in a password manager (CISA advice).
- Turn on automatic firmware updates; replace devices that no longer get updates.
- Put smart devices on a guest or IoT network/VLAN separate from laptops and phones.
- Turn on multi-factor authentication for the hub and cloud accounts.
- Disable features you don't use, such as remote access and UPnP on the router.
