Very popular among people interested in surfing and downloading anonymously, VPNs are a good solution for securing computers, smartphones, and other connected devices. In the following paragraphs, you will find a basic overview of what VPNs are, as well as how to install and configure them.
What is a VPN?
VPN stands for Virtual Private Network. A VPN is a utility that makes it possible to surf the internet worry-free and completely anonymously (we will come back to this point later). Since VPNs ensure the complete anonymity of their users, they are very popular among people who download files illegally. However, VPNs can be useful for many other things as well.
When should you use a VPN?
First of all, a VPN can be used to protect a server from outside threats (a DDoS attack, for instance). A VPN can also be used for downloading files on a P2P network, as previously mentioned. Last, but not least, VPNs are used in certain parts of the world for watching TV programs and accessing prohibited sites or services.
How does a VPN work?
A VPN creates a direct connection between two computers – “insulating” the traffic generated by a remote computer. This insulation will prevent your traffic from being intercepted and analyzed by unwanted parties and will provide you with a measure of protection against hackers (since there will be no direct interaction between your internet connection and other internet traffic). A VPN can be thought of as a tunnel whose walls will protect you from prying eyes and external threats as you travel from point A to B.
