What is VPN and How dumb are you for not using one? A VPN explanation - What is VPN & How Does it Work?

The Virtual Private Network or VPN protects the private web and maintain the secrecy of a private network. VPN allows you to browse the web anonymously from any location - hence you can also access region-restricted web pages.

In recent times, the popularity of VPN as an internet connection is on hype because the operators can use multiple network resources even if they’re not physically on the same LAN (local area network). In addition, you need not replace your ISP.

How does VPN Works?

At first, when you connect to the internet, you’re connected with your Internet Service Provider (ISP) that passes all your internet traffic through ISP servers. This web traffic can also be viewed by your ISP.

In contrast, when you initiate VPN connection run by VPN servers or VPN providers, a secure connection will be established. This means that VPN creates secure “tunnel” between you and your internet destination. Furthermore, the established tunnel encrypts the data sent between you and website and Internet services, ensuring these data can’t be monitored rather it is secured and encrypted.

The highest form of security VPN offers is that it disguises your IP address. This means you’re untraceable. Tunnel under VPN process is as similar as keeping something in the strong box and sending it someone which cannot be visible until it’s decrypted.

Various security protocols have been developed as VPNs which are featuring distinctive securities and features. Most popular protocols are

• IP security (IPSec) - can operate in two modes; transport mode and Tunneling mode used to encrypts data packet message and the entire data packet respectively.
• Layer 2 Tunneling Protocol (L2TP) - This protocol generates the tunnel since it isn't capable of encryption. Pairing with IPSec, L2TP can create highly secure VPN client.
• Point-to-Point Tunneling Protocol (PPTP) - PPTP is oldest and fast protocol but won’t feature encryption. Instead, it tunnels and encapsulates the data packet.
• Secure Shell (SSH) - This protocol creates a tunnel as well as encryption that protects it. SSH protocol employs to secure remote terminal sessions.

Few of the best scenarios that justifies uses for VPNs

• To use Business Network while Traveling
• Access Home Network when you’re away
• Hiding Business activity from ISPs

• Accessing and downloading files
• Best suited for privacy minded and security advocate

Proxy vs.VPN

Many web users often confuse between Proxy and VPN. Though both are different technologies but has a sole aim to protect user’s identities. A proxy server achieve two major functions; boosting performance and filtering requests. It works as a intermediate between one computer and another computer as a firewall servers.

As per the research, VPN is more likely to have 100% encryption and security than Proxy.
