About this video: In this video, I talk about what a VPN is, how VPNs work, and why you should use a VPN to protect yourself online. Thus, this is an in-depth look at everything a VPN does while telling you everything you need to know about them.
To get started, VPN is short for Virtual Private Network, and in the olden days, VPNs were used by corporate employees to access their offices while remote - when they needed to access sensitive information in a secure way or get into the office intranet from home.
Now, however, there are many reasons to use a VPN. From protecting your data when using your computer on a public network like at a Starbucks or in a hospital to accessing region locked content or even torrenting movies, TV shows, songs, etc. You can use a VPN to hide and protect yourself when doing anything online.
Now, how does all of this work? Well, a VPN takes the network you are on and makes a private network that only you can see the data going into and out of. For example, your home is a private network. As long as you use a good wifi and router password, only you and those you want to will have access to the data going into and out of it. However, in public, you don't have any control over who is using the network and seeing the data passing through it. Thus, it is important to protect yourself.
A VPN does this by creating a secure "tunnel" across the Internet between you and your Internet destination. This tunnel is created by first authenticating your device with a VPN server. The server then uses one of several encryption protocols to make sure that everything sent between you and websites and Internet services can't be monitored. It does this by creating an encrypted tunnel, which is like putting a package into a box and then sending it to someone. Nobody can see what it's inside the box until it's opened/decrypted.
There are seven main encryption protocols that a VPN could be using, but the most common one that you see with VPN providers such as Private Internet Access, ExpressVPN, and TunnelBear using is called 'Open VPN'. This is the one we will be talking about here.
Open VPN is most common because it is open source and combines all of the most popular encryption methods using SSL VPN for session authentication and IPSec Encapsulating Security Payload over User Datagram Protocol for a secure data transfer. I know that was a lot of tech jargon, but basically, SSL session authentication protects you when it verifies your device, and IPSec protects the transfer.
And there you have it! That is how a VPN works and why you should use them. If you learned something from this video, be sure to give it a thumbs up and be sure to subscribe to the channel if you haven't already. It really helps us out, and it means a lot! Thank you very much in advance.
