Virtual Private Network Protocols

The list of protocols and available security features continue to grow with time. The most common protocols are:

PPTP - The PPTP (Point-to-Point Tunneling Protocol) is an obsolete method for implementing virtual private networks. The Point-to-Point Tunneling Protocol has been around since the days of Windows 95. A main selling point of PPTP is that it can be simply setup on every major OS. In other word, PPTP tunnels a point-to-point connection over the GRE protocol. This is still strong, but not the most secure. Unluckily, the security of the PPTP protocol has been called into question in recent years.

L2TP/IPsec - The L2TP Protocol is an extension of the PPTP used by an ISP (Internet service provider) to enable the operation of a VPN over the Internet. The L2TP over IPsec is more secure than PPTP and offers more features. The Layer Two Tunneling Protocol (L2TP/IPsec) is a route of implementing two protocols together in order to avail the best features of each. For instance, L2TP protocol are used to create a tunnel and IPsec provides a secure channel. Those measures make for a tellingly secure package.

Open Virtual Private Network – Open Virtual Private Network is an SSL-based VPN that continues to gain popularity. Software used open source and freely available. Secure Sockets Layer (SSL) is a mature encryption protocol, and open VPN can run on a single UDP or TCP port, making it extremely flexible.
