What it shows

  • IoT firmware rarely receives updates, making it a persistent network risk.
  • VLAN segregation prevents compromised gadgets from scanning your home LAN.
  • Firewall rules allow established connections from LAN to IoT, but block reverse.

The takeaway

Segregate smart home appliances into an isolated VLAN with one-way firewall rules to safeguard private data.
