Protecting the Smart Home

Smart Home Technologies can be very confusing.  How do you know what to protect, if you don't understand the technologies being used.  Fortunately, we take care of that for you.

The Smart Home Tower of Babel

Different Home Automation, IoT and Smart Devices use different methods to communicate between each other, hubs, apps and web services that they may use to provide functionality.  

The chart above shows some of the features the different optional layers that devices may communicate on.

Fortunately, most installations pick one or two different communication methods.

Communications types

The internet or intranet (inside your home only) layers (shown in green) provide access to remote and app functionality.  These are wifi 802.11(wireless networking) at either 5 GHz or 2.4 Ghz.  Smart Homes primarily run at 2.4 except for Smart TVs / tivos / etc. (they may be best running on ethernet.)

How do the Zigbee and Z-Wave devices interact with Apps?

Zigbee and Z-Wave both are local networking technologies.  For them to reach the internet or intranet (where your apps interact with them), they need to move through a device known as a gateway.  (Sometimes it is called something else, but it is a way to 'translate' from the communications methods at the bottom of the picture and allow them to talk to the internet.

Now that we know the pieces - here is where the risks lie

The bigest threat to a smart home is thorugh the internet (or a device that has internet connections).  Most laptops, tablets, phones, etc have protection through both firewalls and antivirus / anti-malware.  

Smart Home / Home Automation devices have none or very limited protection. 

Contray to what you may think, Hubs , firewalls, routers, etc don't protect these smart / home automation devices.

The internet attack "surfaces" are shown in Red above. These surfaces are what Guard Dog Focuses on.  In particular how to protect each and every device you add to your home.
