Tor is a necessary tool for everyone that wants to surf privately in their browser without getting noticed by ISP, the FBI or NSA. For the former I’m not sure.
Tor was created with one thing in mind, to improve the privacy and security for people that use it.
I bet, at one point of your life you have asked yourself about Tor, how does it work? It doesn’t make a direct connection with any other browser out there. It connects to a number of virtual networks before this connection arrives at their destination. So, they share their information through public networks, but they’re also keeping their privacy.
A majority of people use this tool to browse privately without sharing their location, especially in countries where governments ban a lot of websites for different reasons. If your ISP or another factor that interfere with your network, know your source and destination, it can steal information from you or see your behaviour on the web.
The real reason why users love this tool, it’s to explore the Dark Web. Deep Web is that part of the web that is not visible by normal browsers. Also you can open websites of Dark Web (they finish with domain .onion). The .onion websites can only be accessed by Tor network. The purpose of this approach is to make both the person who access the information and the provider more difficult to trace.
Be careful to distinguish Deep Web and Dark Web. The Dark Web is the encrypted network that connects users and Tor users. In other hand, Deep Web is the entity that contains all the data and links which are not accessed and indexed by search engines.
If you are using Debian, you can install Tor with a single command. Become a root and run the following command:
apt-get install tor
You can also get it from its website.
This article was a quick introduction to Tor and Dark Web. We will write more in depth articles on the following days and also tutorials to keep yourself secure and private on the web.
