-: In this short section of the course,
we're going to cover a few really important security protocols.

SSL and TLS for web,
Secure Shell for remote control of a computer,
and VPNs for securing those remote connections.
This section is going to be fairly short,
as I said, but the concepts are important,

Now, let's get started.
