We're jumping straight into it inside of our virtual lab that we have here in
the
skill. And one thing I wanted to point out is the reason my background looks a
little bit different is because I'm accessing this through remote desktop.
Outside of the adept lab that's within the browser.
Reason I'm doing this is it's easier to capture inside of my video of software
and makes it a little bit smoother and less jittery.
But once you get actually get everything opened up inside the lab itself,
we're going to go straight into Kelly, which is on the top right and it'll
already be in a startup state.
Now you can go ahead and open up Firefox because the first part we need to do
is register for a trial version of Nessus.
Now Nessus can cost a lot of money depending on what version you use.
But there is a trial version of it that we can practice with to get everything
that we need for any kind of course or validation that you want to take later
on.
So once we open up on the top left of our Firefox, I already have built in two
links in particular for you.
And the first one on the top left, I'm going to pop out so I can zoom in a
little
bit is the trial Nessus professional link and then the download link right
below
that the trial Nessus professional link takes you here where you can register
with your own you your own name and your own email address.
And then once you do that, it'll take you to the second link,
which is here where you can select the version of Nessus that you want to
download.
Now here I want to point out that we're download it generally.
This site will take you to whatever it is that you're using best gas.
See as I zoom in for us real quick, you can see that Nessus 10.8.
0.4 was the version that was picked and the platform is Linux and Ubuntu.
Now I'm saying best guess because sometimes depending on the operating
system that you're using, there are some versions of Windows and some
versions of Linux out there that it can't really guess.
So you're going to have to do the drop down to kind of pick which one you want
to use.
So the important thing here to remember for Kali systems is that we're going to
select the Linux and Ubuntu.
Now you'll see that it's selected AMD 64 and right above that is the Arch 64.
This is based on the type of architecture that our CPU is for the host system
itself.
And inside the ADEP Labs, it's an AMD 64 type environment.
On your personal system, if you're using that to install Nessus,
you definitely want to check and make sure what type of processor that you're
using because that download may or may not work because you see right below
that
there's an i386 version.
That's 32 bit.
And the reason that Arch 64 is available is for those posits based systems that
are
running on, let's say, Mac hardware because newer versions of Mac have the Arch
64
architecture type.
Now with that out of the way, we're going to make sure that we have everything
selected and hit download.
And you'll get the EULA or license agreement.
Just go ahead and select i agree.
And it's going to start downloading everything for you.
We'll go to the folder that it's in.
And you can see that I've already done this once, my bad.
Let me close that real quick.
Don't know why that opened up.
We'll delete that extra one and I'm going to drag the just out of habit for me.
I'm going to drag.
I'm going to minimize my Firefox real quick and we'll drag the nessus devian
file to the desktop.
Now I'm going to open up a tunnel on the desktop and we're going to be using
pseudo and all commands are listed below.
D P K G dash I and the dash I is for installation.
And he capital and member were case sensitive and I'm going to have to
complete the nessus file name.
And I'm going to hit enter and then type in my pseudo password for Cali.
And it's already reading the database.
Now this is pretty straightforward and self explanatory once it runs through
because at the end of this, it's going to give us two bits of information that
we
need to actually open up the GUI of nessus.
But this I'm going to skip through this real quick because all this is doing
right now is reading database and doing a installation off the script that's
within the devian package for nessus.
Big point here was point you in the right direction of where to register and
where to download and we'll be right back.
And just like that, it installed and we're taking a look at it on the screen
over there and I'm going to pop out and zoom in and show you those two
tidbits of information that we were just talking about.
First one is is that you can start nessus scanner by typing slash bin slash
system control start nessus.d dot service.
And I have this in the code box below because sometimes that service has been
known to not auto start whenever Cali has booted up.
So you want to run that as a pseudo and that'll get everything going so that
way we can go to the next line and see to actually access the interface of ness
us.
It is HTTPS.
Cali colon 8 8 3 4 8 8 3 4 be in the fort that we're actually accessing this
earth on and you can change that to local host the IP address.
Maybe you have a name within your network or like a Cali sniffer dot
com or something like that just basically it's the DNS name of the system or
the
IP address.
It's non specific.
Now that that's done, we can actually go in to our Firefox again, open that up.
There we go and go into Cali colon 8 8 3 4 and I'm going to jump to the front
and add the HTTPS because that's required and you'll get an error saying
that not that one.
Well, it looks like it didn't start.
So let's go ahead and start the service.
And that's why that's in there.
So let's go ahead and go back here.
I'm going to copy that line right there.
And like I said, it's supposed to auto start sometimes it does sometimes it
doesn't.
The pseudo space and then paste that selection that we just talked about.
It's in the code box below.
And inside of here, we're going to do a refresh.
And you can see that now we get the potential security risk again because this
is an
unsciens certificate for SSL last TLS.
We're just going to go into advance, go down to the bottom and accept the risk
to
continue and get into the initial crank up all necessary.
Now the first thing it's going to be doing as you can see here is initializing.
Sorry, popping after them meant for you and I'm going to pause here because
this
can take anywhere between five and 10 minutes depending on the speed of the
system.
And it's also going to go and download some of the core definitions for
necessary overall.
Once we get to the next portion, you're going to see that it says welcome to
Nexus and there's a checkbox there for register offline.
We don't necessarily need to do that unless you're in that type of environment.
We're just going to go with the straight online registration and click continue
.
Now this is Nessus professional.
So you want to make sure that the portion right here is selected, the radio
button for start a trial of Nessus professional.
And once we have that selected, we're going to hit continue.
Now right here, if you did the first link that we covered, which is the
registration, you can skip this portion or do the registration here.
If we skip it, you'll see that it's requiring an activation code.
Well, I'm going to pop up on the screen what the actual trial screen looks like
.
And I'm putting the link.
This is the third link in this section of the skill.
And this is after you register, it'll point you to create an account and
everything.
Inside of here, you can see I have two licenses.
One active one expired for Nessus professional and I have them blurred out for
reasons.
And you can see that one of them was created really recent and that's the
activation code that I'm going to be using for this particular portion of Ness
us.
Now I am putting the activation code while I had the screen shot up because I
didn't want to give that away.
And it's going to have to be unique for every learner out there.
So that's definitely an encouragement to go get your trial to download a legal
trial of Nessus.
And when you do that, it's going to ask for a user to have a password and for a
simplicity reason that I put in Kelly and Kelly.
And as you can see now, it's currently downloading plugins.
So I'm going to let this pause for just a second because this part right here
will
take an additional five to 10 minutes and we'll be right back.
