VPN tunnels explained how to keep your internet data secure

This may be shocking to you but in this world of online systems, your privacy is at high risk. There are organizations out there who are keeping a track of our online activities 24 x 7 but we are unaware of it. One good example of this situation is the ads that you see when you visit a website and found relevance. Relevance in the fact that these ads are similar to those searches you have searched lately on Google. You may think it as a coincidence but that’s not the case. It’s like you are in the middle of the room surrounded by CCTV cameras at every corner of the room. However, there is a small escape through which you can avoid those systems from watching over you. It is the use of VPN or virtual private networks and proxy servers.

 As the name suggests, a VPN is a private network that extends through the public network. If you use a Virtual private network then you can send and receive data privately without anyone watching on your internet activity. A proxy server acts as an intermediary between sending and receiving of data. It works by hiding your IP address. Both of these systems work by hiding your IP address but there are some differences and this difference is why people choose VPN over a proxy server. A proxy server will only help you to hide your IP address so that you can view a webpage from your internet browser and that’s not enough. A VPN server not only hides your IP in case of Browsing from a browser but also hides your IP from different applications that work online. In case of a proxy server, it does not divert all of the traffic through the proxy network while in a VPN network you will get all your traffic to get through the virtual private network. Let us take a look at what are VPN tunnels and how a VPN helps in protecting your internet data.

VPN tunnels

VPN tunneling is totally based on setting up and maintaining of a network that is logical in nature and the data that is received or sent is encapsulated. This technology ensures that only the receiver and the sender can know what contains the data packets. There are two types of tunneling viz voluntary tunneling and compulsory tunneling. In case of voluntary tunneling, the tunneling is based on your ISP i.e. the VPN creates a tunnel based on your ISP network and creates a connection to VPN client. In case of a compulsory tunneling the carrier provider manages a VPN connection.

Protecting your Internet data with VPN tunneling

VPN acts as an anchor to your internet data as you can rely on a VPN in case of your privacy concerns. To start protecting your internet data you must need dedicated software which will help you to create the VPN. When you send a data over the internet, it contains information of the sender’s IP address along with some other private information like the information of the protocols such as HTTP. In a VPN tunnel connection, the data which is sent as packets are encapsulated in another packet keeping it secure.

Conclusion

There are lots of VPN software out there but not all of them can act similarly. Some of them may be a bit costly and some may leak your information i.e. not so strong. Therefore it is always advised to research adequately about VPN software before subscribing to one.
