1. Don’t connect your devices unless you need to
The first step is to consider what functionality you need from the device. Just because your TV or fridge can connect to the internet, doesn’t mean you definitely want to hook it up. Take a good look at the features it offers and learn exactly what internet connectivity brings before you connect.
2. Create a separate network
Many Wi-Fi routers support guest networking so that visitors can connect to your network without gaining access to shared files or networked devices. This kind of separation also works well for IoT devices that have questionable security.
3. Pick good passwords and a different password for every device
It’s very important to pick strong passwords, but you must also make sure that you pick a different password for every device. If a hacker manages to get one of your passwords, they will typically try it with other services and devices. Reusing passwords is not a good idea. Use a password manager to keep track of all your passwords.
4. Turn off Universal Plug and Play (UPnP)
Sadly, UPnP can make routers, printers, cameras and other devices vulnerable to attack. It’s designed to make it easier to network devices without configuration by helping them automatically discover each other. The problem is that hackers can also potentially discover them from beyond your local network because of vulnerabilities in the UPnP protocol. Is best to turn UPnP off completely.
5. Make sure you have the latest firmware
If you want to make sure you have the latest security patches and reduce the chances of a successful attack, then you need to keep your firmware fully updated. Vulnerabilities and exploits will be fixed as they emerge, so your IoT devices and your router need to be regularly updated. Automate this wherever possible or set a schedule to check for updates every three months or so.
