Today is the first lesson of the VPN class: what is a VPN? Through a concise and precise article, you will know what a Virtual Private Network is at the end of your reading. While you may not know how it exactly works, you will get the broad outline. OK now stop talking to your neighbour, look this way please, and let’s start to understand what is a vpn and what is it used for.
What does VPN mean? VPN connection what is it?
Understanding VPN connections might seem hard but the truth is , it isn't. First of all, the definition of VPN: What is a VPN connection? According to Wikipedia (yes, even teachers use Wikipedia, what do you guys think?), a virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
Well, that didn’t help much, did it? Let’s find a better way to put it. It is a network. And this network is virtual in that it establishes a virtual bridge between a user (you, for example) and a server (located anywhere on earth). Finally, this network is private because to get access, you need to have an account with login credentials (username and password).
VPN service what is it? So you connect to a server and then this server connects to the Internet for you. That’s it.
VPN and security
If you are missing the point. Don’t worry, it is just the beginning. And you will soon know what is a VPN. Now a bit of history. Does anyone know why VPNs have been created? A clue: it has to do with business… Nobody?
Originally, companies created VPNs to protect their communications from industrial espionage. Because there are increasingly simple ways to intercept data travelling to a network. Have you heard of MAC spoofing and Firesheep for example? Two solutions to hack information.
That’s why a VPN offers an encrypted connection from point A to point B. A VPN uses an encrypted data transmission and a tunnelling system to securely route the data between these two points. Back and forth. As a result, your data is encrypted and protected.
VPN and privacy
Security sounds good, right? What about privacy? Good news: a VPN also means a better privacy! Indeed, the VPN replaces your IP address with the IP address from the server where you are connected. And you can connect to any server of the VPN provider. Therefore, you can have several different IP addresses. For instance, you may live in London and appear to be in New York with the help of the VPN. So what is a vpn and what is it used for, privacy is certainly one of the main things.
To summarize, when you are using a VPN: first, nobody can intercept and use your data. Second, nobody can know which websites you are visiting.
VPN and censorship (geo-restricted content)
Understanding VPN connections and censorship is important. But that’s not all! Indeed, there is another good point related to the privacy method described above. Indeed, connecting to an IP address from any country means that you can unblock all the geo-restricted content from the country you connect to. Imagine that you want to watch American Netflix from your home in Leeds. Without a VPN, it is impossible. But with a VPN, you can connect to an American server and easily access US Netflix!
And it is the same thing the other way round. If you are on a trip in China, with a VPN you can watch UK Netflix from abroad or watch the BBC iPlayer. Furthermore, you can unblock content and get access to censored websites like Facebook or Twitter. So that answers the question - VPN connection what is it?
Most journalists connect to a VPN to bypass restrictions and censorship when they’re away. That way they can stay free on internet.
To summarize, with a VPN you can protect your data and privacy and access websites and content that are usually restricted.
VPN Service what is it: the protocols
Several protocols are available today. The most common ones are:
- PPTP: one of the first protocols (approximately since Windows 95)
- L2TP/IPsec: one of the most secure protocols with a tunnel
- OpenVPN SSL: the most flexible and popular open source protocol
More and more people are using a personal VPN, as more and more interactions (buying, selling, dating etc.) appear on the Internet. That’s why you have so many choices when it comes to VPN providers.
Some companies offer free VPNs, while most of them require a subscription. All their networks are different. Each network has specific characteristics (speed, simultaneous connections, firewall, cost, server location…).
BE CAREFUL WITH FREE VPNs! Indeed, nothing is ever really free in this world... Unscrupulous companies might collect your data and browsing habits for commercial purposes or worse. Also, they might sell your bandwidth. Or use you as a botnet. Using a free VPN will cause you a lot of problems. But now you are informed: use a free VPN at your own risk.
