The Internet of Things (IoT) is about the use of the internet in your home with any device that can connect to the net. It seems like a good idea and in fact it is, but sometimes it can happen that that device has a very low level of security and can reduce the privacy of your data.
Being an emerging technology and in which any unconventional device can connect to the internet to improve its functions can lead to privacy issues. An example would be a coffee maker that shows you time. That coffee maker has a rudimentary operating system and all it does is connect to a server owned by the company that manufactures it and shows it to you on a screen (display).
Shodan is a search engine for devices connected to the Internet. Web search engines, such as Google and Bing, are great for finding websites. But what if you’re interested in measuring which countries are increasingly connected? Or if you want to know which version of Microsoft IIS is the most popular? Or do you want to find the malware control servers? Maybe a new vulnerability came up and you want to see how many hosts it could affect? Traditional web search engines don’t allow you to answer those questions.
Shodan collects information about all devices directly connected to the Internet. If a device is connected directly to the Internet, Shodan queries it for publicly available information. The types of devices that are indexed can vary greatly: from small desktop computers to nuclear power plants and everything in between.
There are several problems with devices that use the IoT that have to do with your privacy and it is very important to check all their settings. These issues include:
If you have an idea of buying a device that connects to the internet it is a good idea to follow a series of recommendations to prevent any type of leak of your data from occurring. They would be for example:
