How to use VPN in Linux?
Before discussing
the installation process, we will, in brief,
discuss the
VPN technology.
Virtual private networks are at first used in private industries and
government institutions to maintain a group of people even when they are
off-site. However, people have found a way to share their servers with other
people without transferring any information about the sender and receiver.
This made VPN popular and useful for a lot of users and mostly for hackers
because of its ability to hide the location of the user.
Why is VPN useful to hackers?
a) Virtual private networks hide the network
address of your system and
link it with another so that you will have anonymity.
b) Virtual private networks can help you get past through a lot of firewalls
and intrusion detection systems that are built-in industries.
c) Virtual private networks not only help you hide your information but also
helps to make sure that all of your network information that is being
transmitted is encrypted. Not sure how this works? Let us give an example.
Imagine that you are using a public WiFi network where a lot of other users
are connected. Not all WiFi dongles have WPA2
advanced security
configuration so your network packets that consist of a lot of sensitive
information
including your passwords, credit cards can be easily
compromised by someone who is on the same network and using wireless
networks sniffing tools like air crack.
Due to these complications, virtual private networks
are recommended to be
used when you are not an in-home network. Now in the next section, we
will look at how to install any VPN in any Linux systems.
