Introduction: The Weakest Link

Your network is only as secure as its weakest device. Often, that weakest link is a $10 smart plug with a default password. IoT IP Security is the practice of 'Isolating' these fragile devices so they can't be used to attack your main computer.

The 5 Security Rules

  1. Isolate: Put all IoT devices on a separate 'Guest' network.
  2. Change Defaults: Never keep the factory-set password.
  3. Filter: Block all outgoing traffic from IoT devices except for their specific 'Cloud' destination.
  4. Disable UPnP: Never let a device open its own ports.
  5. Monitor: Use an IP scanner regularly to search for new, unrecognized 'Guest' devices.
