People who commute to the world of the internet every day, have heard the word VPN at least once. Many readers may know what a VPN is; However, do not usually use. There may be others who have seen their friends use VPN, but have never used it themselves. Again, one might think that the only job of a VPN is to enter a blocked website. But is that really so? How important is it for you to use VPN?
Let's find out then.
VPN:
The full form of VPN is Virtual Private Network. First of all let's start with a story without going into the traditional definition of VPN. Suppose you live on a small island in a vast ocean. In addition to the island you live in, there are hundreds of other islands nearby. A few too close; But the rest is far away. And the only way to get around these islands is by a medium-sized boat. Now if you have to go to a nearby island, you have to get on that boat. But when you get on the boat you have to assume that none of your privacy is being protected here. Because anyone on the boat will notice what you're doing.
Now imagine that each island there has a LAN (Local Area Network) and that sea is the Internet. The Internet connects the LANs just as the sea connects the islands. And traveling by boat means connecting to a web server. Just as you have no control over the people traveling by boat, so you have no control over your internet service provider. This means that your ISP (Internet Service Provider), which has given you an Internet connection, can observe the movements of your Internet navigator in the same way that one can see what you are doing when you try to travel by boat.
But what if you had a small submarine on the island? Then you could easily travel from one island to another while maintaining your own security and privacy! You can travel as you wish without letting anyone know what you are doing or not doing. VPN works like the submarine in our story. When you're using a public network, there's always a risk of privacy. To avoid this risk, VPN is a way to connect to your own private or private network. It allows you to access the web in disguise from anywhere in the world.
How a VPN works:
vPN encrypts your Internet connection and converts your device's IP address to another. It actually creates a virtual ‘tunnel’ between you and your internet destination. This tunnel is created after a connection between your device and a VPN server. Once connected to the vPN server, that server confirms your privacy through its encryption protocol. As a result, when you exchange information, it goes through a secure tunnel. You can compare this tunnel to sending a letter in an envelope. Just as it is not possible to see what you have written in the letter without tearing the envelope, it is not easy to know what you are doing using VPN.
So the ISP means your internet connector doesn't understand that you are using VPN or what are you doing? The answer is - no, not at all! Of course your ISP will understand that you are using VPN, but they will not tell you where you are going on the Internet, what you are doing. Lastly, if you want a little more privacy, you can use Google Public DNS instead of using your ISP's Domain Name Servers (DNS).
Why use VPN? When to do?
Many people must have guessed why they use VPN. Have you ever considered installing a VPN application? If that is the case then maybe you should try to control your temper. Because, there is still something to be said about using VPN while maintaining security!
Anyway, let's go back to the example of the letter in the envelope. Suppose you want to send a letter to someone. A man has also been recruited to send the letter. But you did not put the letter in the envelope and gave it to the man. Now he can read your letter if he wants to. Your ISP can act just like this guy; If you want you can see what you are doing on the internet. So if you want to avoid that problem, use VPN. Again many readers may think your ISP is very loyal. It is not wrong to think so. But one thing to keep in mind is that the ISP may keep you under surveillance or steal your information even if it does not want to. So it is wise to be careful beforehand. So even if you don't always use VPN, at least use VPN when exchanging personal or confidential information.
Not to mention another thing. That is public Wi-Fi. We all chase after free things! So free Wi-Fi is no exception. Many of us start using free Wi-Fi without thinking about security. But these networks are the most likely to steal information. So the easiest and safest way to use VPN when using these networks!
There is security. In addition to this you can use VPN to unblock any website. That is, if your ISP does not allow you to access a website, you can easily access it using a VPN. Again, if you want to use the Internet with an IP address somewhere other than the IP address given by your ISP, then that is also possible by using VPN.
Is it illegal to use VPN?
For so long I have been talking about disguise, website unblocking and many more. So the question may come, is it not illegal? In a word, no! VPN is just a way to keep your personal information or privacy secret. However, if you have done something illegal using VPN, then it is definitely illegal!
How secure is a VPN?
A VPN can protect you from a rogue ISP. But what if that VPN provider company started stealing your data? Or what are you doing online, start saving them? That could happen! But that will only happen when you start using a rogue VPN provider's application. Here too the matter of running after that free thing can be brought up. When you go looking for software to use VPN, you will see that the number of these softwares is innumerable. Many companies offer free unlimited VPN access. Again, many have to pay to use their VPN service. So don't go for less that your full potential. First try to find out how trustworthy the VPN service provider is. So take a look at the web, try to find out what VPN provider company is offering you.
vPN is undoubtedly one of the best ways to maintain your personal security and privacy on the Internet. But don't think that VPN is the only way to protect privacy. There are many more powerful ways to protect privacy. Tor Browser is one such example. However, it is much more complicated than using a VPN. So all in all it is best to use VPN for an average user. However, for those who are worried about the security of a little unique height, I will come up with the details of Tor Browser in the next article !
