Personal VPN Services is one of those technologies that’s becoming more and more important as more people start doing their work on the road.
So, VPN Services used to be all about securing the connection between “Remote Computers” and “Corporate Offices or Business Offices”. Now in 2016 VPN Services are being used simply protect data asit is sent through the internet.
The Overall idea of VPN or Virtual Private Networking:
The Idea is what happens if you take your DATA, you Encrypt your Data, You can put DATA in to another encrypted tunnel and then the DATA can be send to an end point through the internet.
So, Basically your data is protected twice going through the internet. Means its put in a tunnel and then its encrypted with in that tunnel until it get all the way out to the other side.
Why this is Important?
Is because if people are trying to do network sniffing attacks or “Man-in-the-middle” attacks. Means if they can get in the middle of the connection between your client computer and the server that you’re trying to connect to. Even if they can see the DATA is encrypted so they don’t know what it is.
The Nice PART about VPN Tunnels:
The nice part with these VPN tunnels is they have self protection mechanisms, So that if they see that they are being attacked they actually drop and then they will retry to “Reconnect” using a different route.
Purpose OF VPN (Virtual Private Networking)
So, the purpose of VPN is to Protect your DATA when it goes from “Point A” to “Point B”. This used to be very important in the enterprise world.
For ex, You go home and you’re sitting at your work provided laptop at home and you try to connect to the work network you would set up a “VPN Connection” from there you’ll be able to connect to outlook, or to share files and folders and much more with a Protecd connection.
So, that’s How VPN works
For you and people have been using it for about 20 Years. But now VPN services are becoming more important as more people start using their laptops in “Non-Protected” environments.
If you go and use your laptop computer and use it at a “Startbucks” or a “Cafe” or you use it from a Hotel Room.
The problem is that when you are using a “Public Network” there may be Hackers on that network they try to “Sniff and Grab” your data steal your Sessions or cause all kinds of other problems. VPN is here to safe your and your Important Data and Information from this kind of troubles.
