Most smart-home compromises happen through weak passwords, outdated firmware, or unsafe network settings. The good news: a few changes dramatically reduce risk.

1) Secure the Wi‑Fi basics
- Use WPA2/WPA3 and a long, unique Wi‑Fi password.
- Change the router admin password (not the same as Wi‑Fi).
- Turn off WPS if it’s enabled.
2) Isolate IoT devices
Put smart devices on a separate network (Guest or IoT VLAN) so that if one device is compromised, it can’t easily reach your laptops/phones.
3) Keep firmware updated
Update your router/mesh system and the smart-home apps/devices. If a device no longer gets updates, it may be time to replace it.
4) Lock down accounts
- Enable MFA for smart-home accounts where available.
- Use a password manager to avoid reusing passwords.
5) Safer camera/doorbell settings
- Disable unnecessary remote access features.
- Review who has access (family, installers, shared accounts).
- Prefer devices with clear security update policies.
