What is VPN?<\/h2>\n
A VPN (Virtual Private Network) is a way to securely extend a private network across the internet to another location. The client computer (in this case your computer) makes an encrypted connection to a server which acts as a normal network connection. This technique is usually used in companies to allow their employees to securely connect to their work network from anywhere in the world.<\/div>\n
<\/div>\n
VPNs provide security through tunneling protocols. The security model provides confidentiality<\/b> which encrypts the data and protect it from being sniffed out, integrity<\/b> which prevent the data from being tampered with and authentication<\/b> which allow only authenticated users with a username and password to connect to the vpn server.<\/div>\n
<\/div>\n
When a VPN connection is established, it can be considered like having an Ethernet cable connected to the other machine, just a little bit slower since it is going over the internet.<\/div>\n

What is OpenVPN?<\/h2>\n
OpenVPN is an open source software application that implements virtual private network (VPN) techniques for creating secure point-to-point oconnections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL\/TLS for key exchange. It is capable of traversing network address translators (NATs) and firewalls.<\/div>\n
