Whether it is the camera that helps you keep an eye on your home while you are away or the temperature sensor which helps your heating system keep a cozy temperature, you are probably sending all that data through the cloud. This might be useful for remotely controlling & monitoring your devices, or just collecting data to an online analytics platform that can in-turn help you make the best out of your smart home but can also lead to your data getting stolen. A recent example of this is what happened to CloudPets. An internet-connected teddy bear that allowed kids and parents exchange voice messages had a major security vulnerability which allowed hackers to gain info about their users and even use the cute toy as a spy device. A major cause of security vulnerabilities is users not securing their devices by placing them behind a firewall or changing the default passwords that the device comes configured with. This is most common with IP cameras. There is even a whole website dedicated to providing quick and easy access to unsecure cams. Sadly this does not only apply to cameras. Smart homes, industrial control centers and other online devices are listed and easily accessed from a dedicated IoT search engine called Shodan.
At the end of the day, it is up to the manufacturers to keep the data as secure as possible and to be transparent about what kind of info they are collecting from their users and what they are using it for.
When building the 1oT Terminal, security has been our top priority from day one.
