- jude is waiting at the airport to hop on her flight back home when she realizes that she missed making an important bank payment
- she connects her laptop to the public wi-fi at the airport and goes ahead to carry out the bank transaction everything goes well and jude completes
- her transaction after a couple of days she was wiped off her feet when she learned that her bank account was subjected to a cyber attack
- and a hefty amount was wiped from her account after getting in touch with the bank authority she learned that her account
- was hacked at the airport she then realized that the public wifi she used might have caused her this trouble
- jude wishes that had her bank transfer escaped the hacker's eyes she would not have been a victim of a cyber attack bank officials advise her to use a vpn
- for future transactions especially when connecting to an open or public network like most of us jude had come across the term vpn several times but didn't know
- much about it and little did she think that the repercussions of not using a vpn would be this bad let's understand how the hacker would
- have exploited jude's transaction in the absence of a vpn in this process jude's computer first connects to the internet service
- provider isp which provides access to the internet she sends her details to the bank's server using her ip address
- internet protocol address or ip address is a unique address that recognizes a particular device be it a laptop or a smartphone on the internet
- when these details pass through the public network the hacker who passively watches the network traffic intercepts it
- this is a passive cyber attack where the hacker collects jude's bank details without being detected more often or not in such an attack
- payment information is likely to be stolen the targeted data here are the victim's username passwords and other personal
- information such an unsecured connection exposed jude's ip address and bank details to the hacker when it passed through the
- public network so would you have been able to secure her transaction with the help of a vpn well yes
- picture jude's bank transaction to be happening in a tunnel that is invisible to the hacker in such a case the hacker will not be
- able to spot a transaction and that is precisely what a vpn does a virtual private network more often known as vpn creates a secure tunnel
- between your device and the internet for using a vpn jude's first step would be to install software-based technology known as the vpn client on her laptop or
- smartphone that would let her establish a secure connection the vpn client connects to the wi-fi and then to the isp
- here the vpn client encrypts jude's information using vpn protocols data is encrypted to make sure it is secure
- next the vpn client establishes a vpn tunnel within the public network that connects to the vpn server the vpn tunnel protects jude's
- information from being intercepted by the hacker jude's ip address and actual location are changed at the vpn server to enable a private and secure
- connection finally the vpn server connects to jude's bank server in the last step where the encrypted message is decrypted
- this way jude's original ip address is hidden by the vpn and the vpn tunnel protects her data from being hacked this explains how vpn makes your data
- anonymous and secure when it passes through the public network and the difference between a normal connection and a vpn connection
- after learning about this jude was certain that she should start using a vpn to carry out her online transactions in the future
- this is also applicable to each one of us even if you work remotely or connect to public wi-fi
- using a vpn is the safest option in addition to providing a secure encrypted data transfer vpns are also used to disguise your whereabouts and
- give you access to regional web content vpn servers act as proxies on the internet this way your actual location cannot be established
- vbn 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 so here's a question for you from the given options below identify
- the correct flow of a vpn connection a b
- c d
