What is an IoT device? IoT stands for Internet of Things; these devices are pieces of hardware with a sensor that transmit data from one place to another over the internet. IoT devices include, but are not limited to, smart refrigerators, smart watches, smart fire alarm, smart door lock, fitness trackers, smart lights, echos, google home, etc.
These devices may be smart, but they are leaving security holes in home and business networks. If an attacker gains access to any of these devices and they are on the same network as your primary device (laptop, desktop, smartphone), this attacker now has a direct route to your sensitive and private data on your primary device.
What many do not consider is the nature of these “always on” devices. The convenience of being able to turn your lights on with voice comes at a cost. Devices placed near intimate or private spaces can reveal more than you want. At work, they can listen to passwords and critical business details. Placement is just as important is the network they live on.
How can you prevent this?
Glad you asked! The first major way to mitigate this security risk is to isolate your IoT devices on a separate WiFi network or LAN by using micro-segmentation.
Micro-segmentation is where the WiFi router admin creates VLANs, or virtual networks. These virtual networks act as completely different networks even though they are operating off the same router.
This may sound overwhelming for a non techy. Thank goodness PremierePC is here to help!
A few more tips for IoT devices: change the default password to something unique and secure, know the permissions on all apps you are using, and keep devices updated regularly.
Consider muting devices when not in use to prevent always listening devices. Teach children and staff to be aware of devices and what is said near them.
