And Lou everybody when it comes to my advanced ethical hacking networking penetration testing goes
okay.
Now we are allowed to secure our network posting first.
We have put a server here.
So let's try to make some free configurations because we have already made it here.
So we put this static is 1 1 and then the first Internet.
So we put we set an IP address for it as it is then.
All right.
And then we put it on.
So that's all we need.
So now let's just put the connection on our server to switch.
OK.
So now we can go into what we do server.
So we are just going to to secure our network.
So.
All right.
So let's let's go and made it.
It's gonna make it.
All right.
So let's go and make it so we get on CLIA.
So we present.
Okay.
So here we are in the water.
Tell me not.
So we have to type in order to go to the shop.
Okay.
Now we can take the container
and we need to go in there.
Yeah OK.
So now we are here.
What are we going to do.
We need to set a password for the router okay.
We can type enable and a quotation mark can now.
So we are going to use the password field and the secret field as well.
Well so we type in a word password and then the Presenter Well we will stubborn and we can type prove
let's say anything in the book password.
John.
1 1 0.
Let's see first see what kind of things we have to use.
OK.
So John 1 1.
Okay.
So it was our hope and totally changed it like that.
And now we use this secret.
This is the secret that we are going to use this one because we had two options this one.
So we use password already know we are good.
We would use a secret one.
Okay.
So click here.
Secret make it will keep it secret and then of course enter.
Well so far so good.
Now what we are going to do is we are going to try to put a kind of user name in the water so that when
we turn it due to IP address so it will ask us for a user name that we have set and the password as
well.
So let's make it so we take user name and an additional log we can do.
Okay.
So what will we do to do we are going to take.
There was to say there was any is anything.
Oh blah blah blah blah blah blah.
And we can take this again to see what kind of options we have.
We have two options there.
So we can try to set the user pretty good it's really raw or the secret specify the secret for the user
1 for these videos or we are going to just the password again.
So password in that state now.
John 1 1 0 1 2 3 4.
OK.
That's it.
OK.
Now everything is OK so far so good.
So we can close the terminal and let's try to go to any of these computer or we can choose this one
or this one.
It's not a problem.
So you can choose whatever computer you need and a common form of it.
So it again.
Now we are going to tell net the IP address of the order the IP address of Duty is what.
So let's put it here a little bit and we will hover over a mouse.
It's 2 1 for this serial number.
And for us internet is 1 1.
So let's go and try both of them.
Okay.
So let's turn it into 10 and the water is 1 6 8 and it was 1 1.
Yes 1 1.
So we can try to in two ways or do we move.
I mean do we move or save it for now.
Because it it affects on it.
All right.
So we it was easy just to remove it.
Yes.
The icon visible in you.
And on anything you put it between us.
You see.
So let's waste control or.
Light.
And then now with a C so that we don't have a discourse on almost anymore.
All right so now let's go here again on terminal
cancer knowledge type line machine.
We will use this one good deed be zero 15.
All right.
So let's just as you will to call.
So far so good.
Now we can type game and information.
We will just roll call.
Okay so now when we check if the password is working so we can close it or not and go here I try to
turn at it.
Let's go again.
Let's try it right now.
Okay.
Yeah let's try struck again that it was the IP address of the order.
It's this 1 1 6 8 1 1 1 center.
Okay.
So after that we are haven.
Now we have to put deals in.
So what was always in awe or using it was blah blah.
And Representative and did it pass what was on the Big J.
In a 1 2 3 4.
So wasn't it.
Exactly.
So we are in.
Now we get it.
So we can try to turn at it again from 100 B.C..
So let's say so we go and try to go from here.
They stop and go on line.
So we take this thing the net the IP address of the 12 1 2 1 6 2 1 6 8 1 1 0.
You can.
This is the first Internet IP address.
If you want it it doesn't matter.
You can choose to do it.
It will be working as well you see.
So the reason that it's working because there is is this IP address and then the one one is this IP
address.
Let me show you just a hover over my mouse here.
And then you see it with the wind.
Okay.
Their business is 1 1.
And so your 0 2 0 IP address is 2 1 slash 30.
All right.
So it's got you again.
And I can type or using them.
OK.
It was already time to time it out.
Let's do it again.
OK.
The password is 1 1 2 3 4 was enter.
Exactly.
So we're getting to be sure that if you want you can put quotation mark right dad and you will have
a lot of options that you can use.
All right.
So let's say that it's a different now.
We exist.
It's trying to thing one IP address.
We are NBC.
We only see one.
Let's try to be an IP address of 0 2.
OK.
Yes strata beneath it being my mistake.
So that can be me say 4 2 6 8 1 8 presenter.
So it will not stop because we would mind Steve.
OK.
And so it's strategy like the idea David Kay.
Now we can go see one.
It was be soon.
Yeah.
So let's put it here.
Now let's go here on ABC call that simply same thing.
Not.
Let's being let's say we would being PCC will you see all you see all of us IP address 1 6 OK 16 being
being minus 3 6 6 1 6.
The presenter.
All right.
So as you see guys the coalition is made from the P.C. one too busy to open the P.C. forward to see
is war it's not a problem.
One thing that you have to be aware after you've set your password or you're sick in your secret in
your username.
If you test it.
It does not work.
It would mean that we could do is in that you have to type.
Let me stop this when commencing coding see we looking to see controversy.
Yeah.
You have to take this command line and breast cancer that you get that option and it will be not here
in the studio.
It should be here.
So you type where it is where it will show you.
We will show it to you at the moment.
Would mean literally to you this one you have to take it first so that it works and take this.
After that you have the real core version.
So this is wrong look wait wait wait after.
If you test it either way it will work.
What.
Before that it will not work.
So be aware of that.
OK.
So that's all.
No for the security part.
OK.
Now we are going to show you how to how to establish a firewall on your network.
All right.
So let's click on this.
So we don't need it anymore at all.
It was security.
We see the yeah can can control can close the no comment see that command control see.
Close it.
All right.
So now let's add Firpo emitters to our network.
We are going to serve in a firewall.
OK.
So here we are going to put a firewall between this switch and between the router then we're going to
connect all network to the server.
So we put this over here.
All right.
We can just get a new one on squatch.
