3.2.3 Discussion

Without a firewall, the door to your smart home is left wide open


Walk around your average suburban neighborhood at 10 p.m., and most homes will appear downright sleepy: Doors locked, blinds closed, maybe the glow of a TV in the window. But if you were somehow able to wear glasses that could show radio waves, you’d be shocked at the buzz within. Robot vacuums, smart lights, wireless security cameras, and smart speakers are just a few of the many connected gadgets introduced to homes over the last decade, permeating them with their invisible Wi-Fi and other radio signals.

And with every connected gadget you add, the risk of being hacked becomes greater.

By now, you’ve read plenty of horror stories about hackers and the havoc they leave behind. The reasons will surprise you, especially when it comes straight from a former hacker. If you’re really paranoid, the surefire way to guarantee your smart home's protection is to disconnect entirely. But who really wants to do that?

Instead, experts agree that the best defense is to use a firewall.
