Virtual Private Network

VPN In the most basic definition, VPN is a connection which allows 2 computers or networks to communicate with each other across a public network. It is a very good way to secure connection problems.

The data is sent between the 2 computers or networks through a virtual tunnel. The virtual tunnel is the key component of the VPN because it forms a private link among the computers and networks.

Virtual Tunnel The point-to-point connection that supports the encryption and the authentication of the data being transferred. Tunnel allows the data to pass through in a secure way.

How is the tunnel created ? encapsulation of data for transition forming a fake address conversion of the data to its original state

Advantages of VPN saves money/ no additional equipment is needed (phones etc.) it allows anyone with a good direct internet connection to reach their data. provides a extranet connecting clients and workers.

Types of VPN connections User to network Network to network

3 different protocols under VPN Point-to-point Tunneling Protocol (PPTP) Layer 2 Protocol (L2TP) Internet Protocol Security (IPSec)
