This document introduces VPN technology and its uses. It defines VPN as a technology that creates a direct link between remote computers in a private network over a public one using various protocols. It discusses how VPNs provide secure remote access and communications, enhancing productivity and flexibility by allowing access from anywhere. VPNs allow sharing of files and access to information securely from remote locations. They also circumvent censorship and geolocation blocks by making restricted data and contacts available. The document demonstrates VPN technologies like PPTP, L2TP, IPsec and SSL that provide secure data transfer over the internet.

PPTP (Point-to-Point
Tunneling Protocol) tunnel
protocol point-to-point is a
PPP encapsulation over IP
developed by Microsoft.
L2TP
Layer 2 Tunnelling Protocol is a
tunnelling protocol used to support
virtual private networks (VPNs) It
does not provide any encryption or
confidentiality by itself.
IPSEC
Internet Protocol Security (IPsec) allows
two or more hosts to communicate in a
secure manner by authenticating and
encrypting each IP packet of a
communication session
SSL(TLS)
Secure Sockets Layer (SSL) VPN is an
emerging technology that provides
remote-access VPN capability and allows
users from any Internet-enabled location
to launch a web browser to establish
remote-access VPN connections
VPNto provide security of data transfer from danger of internet
