What is VPN (Virtual Private Network)? and How does it work?.

What is VPN (Virtual Private Network)? and How does it work?.

In simple terms, a VPN (or Virtual Private Network) offers a secure way to connect to the internet, encrypting the data you send over the connection to protect it, while also giving you better levels of privacy online.

It is a secure tunnel between the source and the destination both located on the same network. These are used to protect private web traffic from snooping, interference and censorship.

In simple words, it can also act as a proxy for the user, allowing the user to surf the web in anonymous mode irrespective of his/her location.

Practical use: Some states where web censoring is practiced, VPN services are used by the citizens to access websites that are blocked by the state internet administrative authority.

Top three VPN application benefits:


  • Hides the user IP address and the respective location

It routes the user data through VPN servers located in various locations across the world. As a result the state censoring authority is fooled into believing that the data is originating from a reliable source or IP address and their systems don’t block it.

For example : Facebook USA is blocked in China. As a result all Chinese users that query US based IP’s are denied access at the ISP level in China.

When the same user queries a VPN server located in Australia which is not banned in China, it is granted access, thereafter it browses all the banned and allowed portals sitting in China, as all across the world all the server’s see it is an Australian IP.

These VPN servers have been in news recently as state sponsored hackers use them to hack the govt. portals of an enemy state.

Chinese IP’s are denied access to American govt. Websites, but they use allowed IP’s allocated by various VPN servers spread throughout the world to gain access and thereafter cause collateral damage.

  1. b) Data Encryption

These days VPN’s use different strength levels of encryption which could be 256-bit at max. To provide an enhanced level of data protection. VPN enable users to browse safely at public places without the threat of being tracked or monitored.

  1. c) Browse blocked portals irrespective of your location

Online Censorship is a tool that has become a source of worry for online citizens worldwide. Journalists and their cross border sources living in autocratic territories pass info to each other using VPN services.
