VPN( Virtual private network) 101

  1. What is VPN ?

    From Wikipedia VPN is:
    A virtual private network, also known as a VPN, is a private network that extends across a public network or internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
    When you connect to a VPN, you usually launch a VPN client on your computer (or click a link on a special website), log in with your credentials, and your computer exchanges trusted keys with a far away server. Once both computers have verified each other as authentic, all of your internet communication is encrypted and secured from eavesdropping.

    • You can get through the government’s firewall to browse restricted web sites (e.g. YouTube).

    • You can protect yourself by utilizing its strong encryption while using public Wi-Fi.

    VPN Connecting Two Remote Sites Across the Internet

Establishing one of these secure connections—say you want to log into your private corporate network remotely—is surprisingly easy. The user first connects to the public internet through an ISP, then initiates a VPN connection with the company VPN server using client software. And that’s it! The client software on the server establishes the secure connection, grants the remote user access to the internal network and—bing, bang, boom—you’re up to your elbows in TPS reports.
Many security protocols have been developed as VPNs, each offering differing levels of security and features. Among the more common are:
* IPSec
* Layer 2 tunnerling protocol( L2TP)/IPsec
* Secure Sockets Layer (SSL) and Transport Layer Security (TLS)
* Point-to-Point Tunneling Protocol (PPTP)
* SSH
