Smart home technologies have great promise, but they can also introduce vulnerabilities into our homes. Here are some ways to help you enjoy your new smart IoT devices without jeopardizing your home or your family.
Everything from security cameras and locks to TVs and thermostats can be connected to the Internet today. This means less effort for our daily activities, which is why millions of people around the world have begun adopting smart devices. You can find out more about the Internet of Things on our blog.
However, as we fill our homes with connected devices, we’re exposing ourselves to new risks we’ve never thought of before. There are smart doorbells that can be hacked to let thieves into your home. Wikileaks has shown that the CIA can transform smart Samsung TVs into covert surveillance tools (and hackers can often do the same). The sheer number of unsecured IoT devices is one of the main reasons for massive DDoS attacks becoming more frequent.
The worst part is that it’s hard to say when, if ever, these devices’ built-in security vulnerabilities will ever go away. Here’s why:
Consider what you need the device for, how you’ll use it, and how it might be affected in the event of a hack or other unforeseen circumstances. For instance, smart heating devices and apps ensure that your home is only heated when you’re actually there, helping you cut your energy bills. But how will they affect your heating if your power or internet connection goes down? What can hackers do with your heating if they hack in? We suggest choosing appliances that have dependable security features, even if they end up costing more. Only buy IoT devices from brands that provide regular security updates.
One of the most common security challenges for IoT devices is default login details and configurations, which hackers can use for easy access. That’s actually what happened with the infamous Miraj attack. The first step for enhancing your IoT security should be changing those factory defaults.
Some wireless routers allow you to set up separate guest networks to keep untrusted visitors off your regular network. Consult your router’s manual to create at least one separate network for your IoT devices and connect them there. Then, see how you can boost that network’s security (you can, for example, set up a VPN on your router). You can also create a second network by using a second router. The more you segment your networks, the harder it is for hackers to access all of your devices and information. We also recommend disabling Wi-Fi Protected Setup (WPS) and using only Wi-Fi Protected Access 2 (WPA2) to secure your networks.
Make sure you have the latest security patches to reduce the chances of a successful hack attack. New vulnerabilities and exploits will be fixed by manufacturers as they emerge, so you need to update your IoT devices and your router regularly. The manufacturer can’t always do this for you, and any hackers who didn’t know about your vulnerability will discover it as soon as the patch is published. Set automatic updates wherever possible or make a note to check for updates every few months at the very least.
