VPN: details and information about what is and how this technology works
 

 

Perhaps you've heard of VPNs from different sources or friends, but do you know what it is and what it uses? Broadly speaking, a VPN is intended for Internet security, anonymity, and network connectivity.

 

What is a VPN?

 

Its VPN or Virtual Private Network is a so-called "tunnel" that connects two or more networks. The advantage of this technology is that networks are directly linked, so security is greatly improved. Using a VPN is like when you have two devices, a laptop and a PC for example, connected to the same router.

 

The VPN is not universal, but it is categorized into two categories: VPN Site-to-Site and Remote Access VPN.

 

Remote Access VPN - this is the most used VPN type. Through it, your internet connection is secure, and you will be anonymous, your IP being hidden.

 

Site-to-Site VPN - is used to connect Internet networks over other networks, ensuring the security of the data transferred between them.

 

How does VPN work?

 

VPN can not work on its own. It comes packaged with a protocols framework called IPSec (Internet Protocol Security) that provides security. IPSec consists of three components, namely Data Encryption, Integrity and Authentication.
