If you’re running a smart home network of any sort, then you’ll want to ensure that you’re keeping it secure. If that home network happens to include a variety of smart devices, then would-be hackers will have an even larger ‘surface’ upon which to conduct attacks. Whether it’s a home camera system, a smart speaker, or a television, those extra devices might potentially create a vulnerability.
So, what precautions might result in greater security for home users?
Start With Strong Passwords and Unique Logins
If your passwords are easy to guess, then attackers might stand a better chance of breaking them. What’s more, if those passwords are recycled in many different locations, they’ll be more vulnerable to data breaches. When a password for one service is leaked, it’s best that the same password isn’t used elsewhere.
Each device you use should be protected using unique credentials. A password manager might make it easy for you to compose and remember unique, strong passwords.
Update Your Devices Regularly
Whenever a security vulnerability is discovered in the firmware of a given device, or in the app that allows you to control it, the developer will often address the problem using a patch. But what if you don’t actually download and install the appropriate patch? In this case, you’ll remain vulnerable – and you could potentially miss out on other security benefits.
Set up automatic updates for all of your devices, and make sure that you read the patch notes when they’re released.
Secure Your Home Wi‑Fi Network
Your home network should be protected, using a strong password that’s different from the one your router shipped with. The latest routers will use WPA3 encryption; if yours is older, then it might be worth looking for an upgrade. If you want to log into your home network remotely – for example, to check on your security cameras while you’re on vacation – then it’s worth taking special precautions.
Set Up a Guest Network for Smart Devices
Certain smart devices might be quarantined from others. For example, keeping any work-related computers and systems on an entirely separate network might lend you an extra degree of protection.
Review Privacy Settings on Each Device
In some cases, certain devices will collect data from your storage drives, or even directly access the camera on your phone, and your microphone. Make sure that you review the permissions you’re granting, and that you ask yourself whether a given device really needs what’s being demanded.
Use Encrypted Tools to Enhance Digital Safety
You might use a number of software tools to secure not only the network as a whole, but also certain particular devices. For example, a Netflix VPN program might allow you to switch regions from your router, and thereby explore the library of your favourite streaming service, as though you were browsing in another country!
Monitor Devices for Suspicious Behaviour
We should emphasize the importance of being vigilant. Be on the lookout for strange behaviour in the devices you use and unexplained network activity. If a restart or patch doesn’t fix things, it might be time to investigate further. Change the passwords and login details – and try to rule out the possibility of a physical failure.
Teach Your Household Good Digital Habits
However diligent you are with your software and hardware, it’s also a good idea to think about how you’ll instill the right habits in your family members and teach them to be aware of their responsibilities when it comes to your security. Just as you wouldn’t allow family members to leave the front door wide open, you shouldn’t tolerate questionable online practices, either.
Conclusion
You don’t need to be massively tech-savvy to protect your home network. Through the simple habits and technical steps we’ve mentioned, it’s possible to eliminate the vast majority of the risk.
