What is VPN?

Virtual Private Network is a type of private network that uses public telecommunication, such as the Internet, instead of leased lines to communicate.
Became popular as more employees worked in remote locations.
Gives users a secure link to access corporate network over the Internet

Private Networks vs. Virtual Private Networks

Employees can access the network (Intranet) from remote locations.
Secured networks.
The Internet is used as the backbone for VPNs
Saves cost tremendously from reduction of equipment and maintenance costs.

Remote Access Virtual Private Network
Brief Overview of How it Works

Two connections – one is made to the Internet and the second is made to the VPN.
Datagrams – contains data, destination and source information.
Firewalls – VPNs allow authorized users to pass through the firewalls.
Protocols – protocols create the VPN tunnels
Four Critical Functions

Authentication – validates that the data was sent from the sender.
Access control – limiting unauthorized users from accessing the network.
Confidentiality – preventing the data to be read or copied as the data is being transported.
Data Integrity – ensuring that the data has not been altered
