VPN tutorial

If you're concerned about an eavesdropper listening in to
your internet conversations, then you should consider using
a VPN to encrypt your traffic.
When traffic goes from your computer to the internet,
there are many points along its journey when an
eavesdropper could potentially listen in.
When you use a VPN, all traffic between your computer
and the VPN server is first encrypted.
The VPN server decrypts the traffic and sends it along to
its destination.
This is useful if you suspect you are using any sort of
insecure connection, such as a wireless connection or an
untrusted ISP.
In another video, we discuss SSL, and how to look for HTTPS
in your browser.
It is convenient to use HTTPS because there is nothing you
need to do on your computer.
But HTTPS encryption is provided by the web page that
you are connecting to you, and not all web pages offer an
HTTPS option.
VPN, on the other hand, provides an encryption option
that you control by installing software on your own computer.
Also, HTTPS is only applicable to your browser-based traffic
and cannot protect other traffic, such as voice.
In this diagram, we compare HTTPS, the top diagram, to
VPN, the bottom diagram.
In the top diagram, only traffic from
the browser is encrypted.
In the bottom diagram, all traffic, from any application
on your computer, is encrypted.
There are a few different types of VPNs.
Many people use a VPN given to them by their employer.
Personal VPNs are also widely used, but you should probably
expect to pay a small monthly fee for use.
A good place to start looking for the right personal VPN is
to do an online search for the term VPNs, or personal VPNs,
and your country name.
You can also search in forums and groups for
recommendations, or ask people you trust.
Thanks and safe searching.
