It goes without saying that if your home network is not secure, nothing else in your home will be secure. For most people, they rely their internet service provider to set things up. Be cautious about using the network’s name and password they used. What you really need to do is change it as soon as they leave making sure to use a strong password that is not easy to crack. When doing so, also make sure to choose a network name that doesn’t give away your location or personal details. On a side note, you might want to consider hiding your network from view.
Another option is creating a Wi-Fi network specifically for your smart home devices. This way, if your IoT device is hacked, it will confine the attacker to that network and keep it segregated (from where you do your banking for example). It is also a good idea to set up a guest network for your visitors with smartphones and computers. This way, they cannot see or access your IoT devices.
Enable Automatic Updates
Additionally, make sure your WiFi router has automatic software updates enabled. If security updates aren’t automatic, you may find it hard to apply them, or forget completely. This will leave your WiFi router vulnerable to an attack at all times. Remember, a vulnerable router means a vulnerable smart home.
