VPN tunneling to provide security and anonymity

Security and anonymity is one of the highlights of a VPN service. VPN subscribers mainly look for this particular feature before they sign up with the VPN service provider. Now, from a user’s point of view, it is necessary to understand the process through which they are able to obtain the level of security which they obtain from the VPN service. There are different types of VPN protocols operated by VPN service providers and they include PPTP, L2TP, SSTP, IPSec etc. All these VPN protocols are encrypted and it is not breakable. Encrypted networks are always secure and that is the reason why hackers and snoopers find it very difficult to bypass the system and obtain access to their websites.

Encrypted data networks would work in such a manner that, the data which gets transmitted across the server would be encrypted and encapsulated by the client and the server and this particular data would be de-encapsulated towards the end of the transmission i.e. at the receiving end. Encapsulation is the basic ideology behind the operations of a tunneling network protocol. In addition to this particular effect, the VPN tunneling protocol also operates based on authentication, which means that setup of the VPN service would be authenticated through passwords too, this means additional data security for the VPN subscriber.

VPN tunneling types

VPN service providers offer tunnel based network protocol technology in two different forms namely voluntary tunneling and compulsory tunneling. Both these forms of tunneling are quite normal and are in practice. These two types of tunneling are explained in detail below:

Voluntary tunneling

Main difference between these two types of tunneling lies in the ones that would be managing the VPN connection setup. In the case of voluntary tunneling, it would be the VPN client which would be managing the connection setup. Client would initiate the connection by establishing network with the carrier network provider. This particular connection would be utilized by the VPN application to establish the tunnel based network.

Compulsory tunneling

In compulsory tunneling, it is just the opposite; carrier network provider would manage the VPN connection setup. If say, for example the client is trying to make the connection with the carrier network provider, then the carrier network provider would immediately create a VPN connection between the server and the client. The difference between these two tunneling protocols can also be seen in the form of the steps involved in establishing the tunneling. Voluntary tunneling is a two-step process, whereas compulsory tunneling is a single step process.

VPN front end processor is the other name given for a compulsory tunneling protocol. It is also termed by names such as Point of Presence server or Network Access Server. The data transfer would be kept secure in this particular tunneling since it would hide the server details from clients. The only drawback which can be seen from this particular tunneling is that, the service providers should maintain a proper FEP device.

Tunneling protocols

Coming to the different types of tunneling protocols, the most popular ones include PPTP, L2TP, and IPSec etc. All the different tunneling protocols are discussed further. Most of the VPN service providers offer their servers operating out of these three protocols. Subscribers should choose a VPN service based on the type of VPN protocol which would support the device utilized by the user.

PPTP

PPTP stands for Point to Point Tunneling Protocol. PPTP was initially framed for Windows users, but later as a result of development and advancement, it has been made available for even Mac users. PPTP has built in support features for the client servers. Windows are also regularly improving the features pertaining to the PPTP protocol.

L2TP

L2TP is Layer Two Tunneling Protocol. PPTP offers stiff competition for L2TP. This protocol is also being utilized by most of the users and it is the most popular one, standing next in the queue behind PPTP.

IPSec

Internet Protocol Security is what is shortly termed as IPSec. IPSec can be utilized together with other forms of protocols such as PPTP or L2TP and it is generally a combination of the many protocols.

Security and anonymity

A tunnel based encrypted network protocol would have multiple levels of security. This particular secured network cannot be broken by hackers and snoopers. Business professionals and tourists who travel across borders might be in need of performing financial transactions. Banks operating out of a particular country cannot be accessed from a different location. Banks operate a secured network and in order to maintain this high level of security, banks do not allow access to other country users. In order to gain access and to perform the financial transaction in a secured manner, the user should require VPN tunneling protocols.
