How VPN Tunnel Secures your Online Privacy
Virtual Private Network provides a safe and secure networking system. VPN enables us to share files and data in a secured and a risk free environment. The data is exchanged between various branches of same company. The use of VPN makes it easier to transfer the data without giving the chance to the rivals and hackers to hack into your system and getting out the trade secrets of the business. Therefore it has become essential to have a Virtual private network.
VPN tunnel works as a subway network. It helps to create a network that is safe and secure in between the public networks. VPN tunnel uses software that works as gatekeeper. It closes and opens at client’s order. A datagram based protocol is used in the tunnel to ensure the parameter of the both end is the same. While transporting the information through tunnel data is encrypted and decrypted when the receiver receives the data.
There are number protocols used in the VPN tunnel that help to secure the data transmitted through the VPN or Virtual Private Network. VPN can create a virtual office through which they can utilize the full potential of the employee. The employee can work from the remote places as they are working from the office space.
VPN or Virtual Private Network mask your IP address with another IP address. It becomes impossible to locate these IP address as it bounces from the server of different location. VPN has server in the 24 countries of the world.
VPN tunnel makes the transfer of the data safe. We often access in public with the help of the Wi-Fi networks. If the hackers are prying behind your back, even then your personal data will be secured. It is protected through various protocol and encryption.
Types of VPN Tunneling
There are two types of VPN tunneling used. They are voluntary and compulsory.
Voluntary VPN tunneling is set up by the client. The client creates a tunnel with the service provider. In voluntary tunneling connection is set up two steps.
In compulsory tunneling the connection is made through the carrier network. Therefore it is a single step set up in comparison to the two step setup of the voluntary tunneling.
These tunnels protect our personal data. It cannot be deciphered by the hackers.
Protocols used in Tunneling
Various numbers of protocols are used in VPN tunneling. There are mainly three protocols that are used in VPN tunnel.
Layer Two Tunneling Protocol (L2TP)
This protocol is created and developed by CISCO and Microsoft. The best qualities of L2P and PPTP are combined in this protocol.
Internet Protocol security (IPSec)
IPSec is a protocol which is used in VPN tunneling. They are created with various features of different protocols. Therefore it is profitable option to use Internet Protocol Security (IPSec).
Point to Point Tunneling Protocol (PPTP)
PPTP is used for dial up network connection. It helps to access from remote areas while using the VPN.
VPN and tunnel application protects our data through encrypted message transfer through the internet. The VPN tunnel sends data in various channels for the VPN service provider’s client in order to hide their identity.
