Our homes are getting smarter, but that doesn't mean they are getting safer. These days, it's not uncommon for everything from kitchen appliances to light bulbs to be connected to the internet via a person's home WiFi network. While these smart devices may offer some level of convenience, they also offer hackers a new way to break into your network. For example, a few months ago hackers figured out a way to exploit a Samsung smart fridge to take over a person's Gmail credentials. "If it's connected, it's vulnerable," Yossi Atias, the CEO of the smart home security company Dojo Labs, told Tech Insider. "If vulnerabilities are built into it, they will be found and the device will be compromised." While manufacturers of smart home devices are beginning to pay more attention to securing their products, there's still no solution that offers complete security for all connected devices in the home. But that may be about to change. New devices could keep hackers out of your home A few start-ups, including Dojo Labs, are looking to become the leaders in smart home security. The Dojo system is composed of three parts: a pebble, a white cybersecurity engine, and an app. The cybersecurity engine is the key part of Dojo — it's plugged directly into your router so it can detect unusual activity occurring over your WiFi.
