What is VPN (Virutal Private Network)
What is a VPN?
As we all browsed the internet to gain access to any particular resource but if you want to access the files and resources which are restricted in a less secure network there comes the network called "VPN".VPN is abbreviated as virtuaal private network is a technology that creates a safe and encrypted connection over a less secure network,such as internet.
VPN technology was developed as a way to allow remote users and MNC's to securely access corporate applicationsaa and other resources.As security is concerned in VPN data travels through secure tunnel,and VPN users must use authentication methods including passwords,tokens or other unique identification procedures to gain access to the VPN server.
How does a VPN work?
Here’s how a VPN works for you, the user. You start the VPN client (software) from your VPN service. This software encrypts your data, even before your Internet Service Provider sees it. The data then goes to the VPN, and from the VPN server to your online destination . The online destination sees your data as coming from the VPN server and its location, and not from your computer and your location.
Here's how your data flows in open to the internet

Now here's how the same connection look with a VPN enabled
When you use a VPN service, your data is encrypted (because you’re using their app), goes in encrypted form to your ISP then to the VPN server. The VPN server is the third party that connects to the web on your behalf. This solves the privacy and security problem for us in a couple of ways:
1. The destination site sees the VPN server as the traffic origin, not you.
2. No one can (easily) identify you or your computer as the source of the data, nor what you’re doing (what websites you’re visiting, what data you’re transferring, etc.).
3.Your data is encrypted, so even if someone does look at what you’re sending, they only see encrypted information and not raw data.
How Secure is a VPN?
VPN security depends upon the services provided by the VPN Providers as no two services are identical in their offerings or security.
VPN Protocols:
VPN protocols define how the service handles data transmission over a VPN.The most common protocols are
PPTP(Point-To-Point Tunneling Protocol)
L2TP/IPsec(Layer 2 Tunneling Protocol)
SSTP(Secure Socket Tunneling Protocol)
IKEV2(Internet Key Exchange, Version 2)

Does a VPN Make Me Fully Anonymous Online?
In a word, no. But the extent to which it does is still impressive.
Without a VPN, your connection is fully open, and your ISP, the cafe WiFi router, any server along the way, or a person with the right tools can look at your data. Using a VPN solves many of those problems by encrypting your transmission and making it appear as if it’s the server itself that’s making the connection and not you.
