Computers and smartphones aren't the only gadgets in our lives in danger of getting hacked. Smart home security cameras, children's toys and even our routers, the device that takes us on the internet, are all vulnerable. However, that doesn't seem to be deterring people from buying connected devices.

We like these smart speakers, robot vacuums and video doorbells so much, that the smart home market is expected to hit $53.6 billion by 2022 (up from $24.1 billion in 2016), according to insurance company Assurant.

As we bring more connected products into our home in the coming new year, it's helpful to take steps to protect smart home devices from online attackers, the best that we can. Here are some famous hacks — and what consumers can do to try and thwart these attacks.

Researchers found security vulnerabilities in a doll that let children ask questions, and answer back. When prompted, the doll, My Friend Cayla, would respond by connecting to online servers to bring up answers — much different than recorded answers typically found in toys. Germany actually banned the toy, so concerned about its spying potential.

More than one-quarter (27 percent) of U.S. consumers already own more than three smart home devices, according to research firm GfK. As we bring more into our homes, it's important to keep tabs on who is tapping into those devices, to make sure their acting as they should. A robust firewall, like Cujo, which works in tandem with routers, can help to monitor traffic to the connected devices in our home.
