To complete our set up of our ethical virtual hacking labs, we're going to see how to set up two different
networks.
We usually like to do ethical hacking inside a closed virtual lab.
That means a private host only network where we can only see the other machines in our ethical hacking
lab not see out to the Internet or vice versa.
Now have the Internet see into us.
So we're going to create a host only network in virtual box that will be a private network just for
our machines and our virtual hacking lab.
That means that we're only going to be able to see from one machine to the other and to our host computer
and from the host computer down into our individual machines.
So this host, only the network is going to have an address range of 10 dot dot three dot some number
from four to 100.
You can go anywhere from one to two hundred fifty four here, but we'll use the range from four to 100
for our machines.
It'll do a couple of things for us.
First of all, it will keep us safe from the Internet so no one can sniff around and find out Linux
box.
No one can sniff around and find out Métis floatable box or even our Windows 10 virtual machines or
Android and so on.
But it will also keep our local area network and the Internet safe from us.
The Calli Linux boxes we saw when we set it up has tons of tools installed in it for Forensic's, for
penetration testing, for real hacking.
And we need to be responsible when we're using that Kelly Linux machine, when we're ethically hacking,
we don't hack networks that we don't have permission to access.
So we can do some things at home in our local area network.
But we usually don't even want Cauli sniffing our Blu ray disc machine, our wireless adapter for wireless
Internet, any security cameras in the house, things like that.
So we want to make sure that we protect ourselves from the Internet and protect the Internet and our
local area network from our Caleigh machine especially so that 10 Dorota three will be our private network.
Then sometimes we'll want to connect to the Internet just to surf, surf the web or to get some updates
for a particular machine.
And we'd still like to be able to see from one machine into another when we connect it out to that public
Internet.
In our social engineering hacking example, we're going to see how to copy the Facebook homepage and
we'll see how to use this ten, not nine public network to set up a fishing page that could capture
user's credentials.
That's really useful for testing in a corporate environment to make sure that people are not clicking
through to phishing emails.
And if they are, we usually do some extra training with them.
We'll see that in the social engineering section coming up.
But for our lab set up to be complete, we need both a private network and a public network.
The private network will be the ten point three set of addresses and our public network will be ten
point nine.
When we see ten point three something, we'll know that our computer is in a private hosted only network
protected from everything and everything's protected from us.
When we'll see the ten point nine, we'll know that we are on the public internet.
We can connect and surf to a website, for example, to Facebook or to Google, or we can do our updates
for Windows updates or do a pseudo app to get update for our Linux boxes.
But we will also be exposed to the Internet and the Internet will be exposed to us.
So we will usually live in this private network.
But it's good also to have this public managed network set up so that we can still see from one machine
into the other and we'll be able to connect out to the public Internet to get updates or do actual Web
surfing or reconnaissance work if we need to.
So we'll see how to set up our private hosts only network next and we'll see in the next lesson.
