How a (VPN) enables you to prevent a cyberattack: Example

Jude (woman's name) is waiting at the airport for her flight home when she discovers she's missed an important bank payment, connects her laptop to the airport's public WiFi, and goes to check Jude completes her transaction after a few days, she was wiped off her feet when she learned that her bank account had been attacked by a cyber attack and that a large amount was deleted from her account after she logged on. 

Contact the banking authority that found it out that his account had been hacked at the airport, then he realized that the public WiFi he was using could have been causing this problem for him. Judah wishes he would not have been the victim of what VPN is and how it works. if his bank transfer had escaped the hacker's eyes, officials advised him. Use a VPN for future transactions, especially if you are connecting to an open or public network. Like most of us, Jude has come across the term VPN several times, but she didn't know much about it and little, considering the implications, not using a VPN would be that bad.

Importance of Using VPN:

Let's understand how the hacker would have exploited Jude's transaction without a VPN. Jude's computer first connects to the Internet service provider ISP, who provides Internet access. It sends its data with its IP address Internet protocol or IP address to the bank's server is a unique address that a certain device, be it a laptop or a smartphone on the Internet, recognizes when this data is transmitted through the public network. The hacker passively observes the data traffic from him is intercepted by the network. 

This is a massive cyberattack in which the hacker collects Jude bank data without them being detected more often or not during such an attack. Payment information is likely to be stolen. The specific data here is the victim's username, passwords, and other personal information. routed through the public network, so you could have secured your transaction with the help of a VPN, well, imagine that the Jude Bank transaction takes place in a tunnel that is invisible to the hacker, in which case the Hackers will not be able to detect a transaction, and that is exactly what a VPN does, better known as a virtual private network.

What is a VPN?  

A virtual private network, better known as a VPN, is a service that provides a secure tunnel between your device and the Internet. With the help of a VPN, you can conduct a secure online transaction. Data transfer, VPNs are also used to disguise your whereabouts and give you access to regional web content.

How a VPN works?

VPN creates a secure tunnel between your device and the internet in order to use a VPN. Jude's first step would be to install a software-based technology called a VPN client on your laptop or smartphone that allows you to establish a secure connection, the VPN client connects to the WiFi and then to the ISP. Here the VPN client encrypts Jude's information using VPN protocols, the data is encrypted to ensure that it is secure, then the VPN client establishes a VPN tunnel within the public network that connects to the VPN server The VPN tunnel protects the Jude information from being intercepted by the hacker, the IP address of Jude and the actual location in the VPN server are changed to enable a private and secure connection.

Finally, the VPN server connects to the bank server of Jude in the last step where the encrypted message is decrypted in this way the address of Jude's original IP is hidden by the VPN and the VPN tunnel protects your data from hackers. This explains how VPN makes your data anonymous and secure as if they go through the public network and the difference between a normal connection and a VPN connection after meeting this Jude was certain that she should use a VPN for his online transactions in the future, so does each of us even if working remotely or connecting to a public Wi-Fi network through a VPN is the safest option.

Advantages of Using VPN:

1) In addition to providing secure encrypted data transfer, VPNs are also used to disguise your whereabouts and give you access to regional web content. 

2) VPN servers act as proxies on the internet this way your actual location cannot be established.

3) VPN enables you to spoof your location and switch to a server to another country and thereby change your location for example by doing so you can watch any content on Netflix that might be unavailable for your region.
