Virtual Private Network – The Working

Now you know that VPN provides you more security, more accessibility, more anonymity, there is a need to understand how it works.  

Your machine is a client and the data will be entered from one end of the VPN server; it will be encrypted before reaching out to the internet.

The other end of the VPN server will decrypt this data at the time when it will reach the desired device such as email or web server. The same cycle gets repeated on the way back from the destination (the client machine) to source or vice versa. 

You can also easily install a VPN server yourself. The specified software is often downloaded free from charge.

Let’s take the instance of the traveler. He’s regularly on the road and would like to quickly check his e-mails and edit a document at the airport on the way to the subsequent appointment.

To do this, he logs into the airport’s open WLAN, which is often unencrypted. Unencrypted means it’s also relatively easy for laypersons to read the info traffic that runs over the WLAN.

A freely accessible software or mobile app is sufficient for this. There is, therefore, a risk that sensitive business data, but also customer and employee data, are going to be tapped.

Additionally to the loss of the info, there’s a risk of image damage and fines from the supervisory authorities.

A suitable VPN application ensures that unauthorized persons can not read the info. Also, it enables access to drives that are located on the corporate server and will only be available within the company network. Without VPN, centrally stored documents can’t be processed.
