How would you like your package to be delivered by the courier service? Do you want it to be delivered quickly or do you want it to be properly packed and safely delivered, even if takes longer than usual? In the world of VPN, those questions are answered by the data tunneling protocols.
While a wide variety of VPN protocols are available for commercial and individual users, the PPTP VPN type remains popular on account of increased functionality.
The Good Old Days
Many members of Generation Y will remember the days when the modem was at the heart of the internet connection as it controlled data transfer between the client and the remote server.
The Remote Access Service (RAS) protocol came forth to allow functionality over telephone lines. Do you remember the funny noises the modem used to make before establishing the connection? “eeen-aaan-kading-kadung……”
The first RAS protocol was the Serial Line Internet Protocol (SLIP). SLIP supported the initial network protocols (TCP/IP) but quickly became obsolete when the dawn of advanced protocols (IPX/SPX) demanded the development of the Point-to-Point Protocol, or PPTP as they are most commonly known.
The Roots of the Point-to-Point Tunneling Protocol
Dating back to the 1980s, the Point-to-Point Protocol (PPP) served as a bridge between the physical link at the user’s end and the Internet Protocol.
Responsible for establishing a two-way point-to-point connection, the PPP was popular for its simplicity and effectiveness. This was the first protocol to achieve formal recognition as a VPN protocol.
Subsequent developments in internet technology changed all that sooner than anticipated. The need for more security and faster data transmission led to the development of the Point-to-Point Tunneling Protocol. (Remember, tunneling begins with the encapsulation of data at the source, followed by the routing of encapsulated data packets and concludes with the decapsulation of data at the destination)
The All Time Favorite – Point-to-Point Tunneling Protocol
The Point-to-Point Tunneling Protocol (PPTP) goes one-step ahead of its predecessor, PPP, by establishing a virtual tunnel for an even safer transmission of encapsulated data packets.
Even though PPTP has native support from Windows
, it is widely used on Mac
platforms because of speed and compatibility.
The PPTP borrows authentication protocols from the PPP and often comes under fire for being far too traditional and vulnerable if used without encryption.
Make the Intelligent Choice
When choosing your VPN protocol, make sure you begin by identifying your VPN use. To play it safe, make sure you pick a VPN provider that guarantees you access to the PPTP protocol.
Most VPN providers
will limit protocol access depending on the pricing package you purchase. We recommend finding a VPN service provider that gives all-round protocol access regardless of the pricing plan.
Here is the list of best PPTP VPN providers.
PPTP VPN Protocol & Encryption – Hand in Hand
If used without encryption, publicly available services such as CloudCracker and browser add-ons like FireSheep can easily crack PPTP connections by using network sniffers (fish-net programs designed to capture low-level data packets).
Once your key has been extracted, the task of accessing all your data traffic transmitted across the network is as stealing candy from a baby.
