What is Virtual Private Network? |
|
Answer» A virtual private network (VPN) is a secure connection over an unsecure network, such as the internet. A VPN service creates a safe and encrypted connection across an insecure network like the internet. A VPN connects a private network with a public network like the internet to extend the network. The term “virtual private network” implies that the network is accessible by users sitting in the remote area. It uses tunneling protocols to create a secure connection. Consider a scenario where a bank's corporate office is located in Washington, USA and uses a local network of 100 computers. Mumbai and Tokyo branch offices are used to connect with the head office using a leased line, a costly and time-consuming process. Using VPN, we can eradicate this challenge in a powerful way. |
