VPN (Virtual Private Network) is a secured private network connection built on top of
public telecommunication infrastructures, such as the Internet. VPN has become more
prevalent due to the benefits of scalability, reliability, convenience and security. VPN
provides remote offices or individual users with secure access to their organization's
network. There are two types of VPN access: remote-access VPN (connecting an
individual device to a network) and site-to-site VPN (connecting two networks together).
Remote-access VPN allows employees to access their company's intranet from home or
outside the office, and site-to-site VPN allows employees in geographically separated
offices to share one cohesive virtual network. VPN can also be classified by the
protocols used to tunnel the traffic. It provides security through tunneling protocols:
IPSec, SSL, L2TP and PPTP.
