>> Welcome back to the summary course
00:00
in building your InfoSec Lab.
00:00
I'm your host and Instructor, Kevin Hernandez.
00:00
In our last lesson, we basically connected our lab,
00:00
integrated our Firewall into our network.
00:00
In today's lesson, we're going to
00:00
expand in that Firewall PFSense,
00:00
some of its applications such as
00:00
Nmap. Now let's get started.
00:00
Now let's login into PFSense.
00:00
[NOISE] We're going to
00:00
go to System, Package Manager.
00:00
Available packages.
00:00
If you remember correctly,
00:00
this is where we can install
00:00
extensions to our next-gen firewall.
00:00
You can see there are several options.
00:00
Now, I have counted approximately
00:00
>> around 70 applications
00:00
>> or extensions that can be installed.
00:00
If you remember from a previous lesson,
00:00
you have IDS, you have web proxy, among others.
00:00
Now, one of them that I really
00:00
want to install since we've been using
00:00
it in order to map properly our network, this Nmap.
00:00
Let's go ahead. Here we go.
00:00
[NOISE] If you click here,
00:00
you actually go into
00:00
the documentation diagnostics Nmap
00:00
[inaudible].
00:00
Let's go back. Let's go ahead and click "Install".
00:00
Confirmation required to install.
00:00
Yes. Let's go ahead
00:00
and wait a second for it to
00:00
download and install the package.
00:00
You can see, shows that it
00:00
has been successfully installed.
00:00
Now if you recall correctly,
00:00
Diagnostics and then scroll down. Here it is.
00:00
Here we go. Interesting. If you remember correctly,
00:00
[NOISE] looks not so
00:00
different from what we have in
00:00
our Ascend map in our Windows installation.
00:00
Ip host name right here, which is target,
00:00
the interface and we have the scan method.
00:00
You have seen, which is the command,
00:00
basically write ping UDP, etc.
00:00
For example, we can go ping,
00:00
attempt to identify service version and this enable
00:00
operating system detection and let's do it anyway.
00:00
Let's go to the LAN, scan the outside.
00:00
Let's save 128.1.0/24. Let's go ahead and scan it.
00:00
It has actually taken a little while to run.
00:00
I actually go ahead and run only a
00:00
>> ping scan and going to
00:00
>> target specifically 39 its scan.
00:00
Actually, that was a lot quicker than other frequency.
00:00
If you recall correctly,
00:00
this is our ESI box.
00:00
[NOISE] Back, you can see it was a very simple tool.
00:00
It's very basic the scanning
00:00
compared to the application itself.
00:00
That can be highly related to
00:00
the amount of resources we have assigned to this box.
00:00
Obviously, the more resources you put,
00:00
the faster does console run.
00:00
Part of the reason why it will run
00:00
faster in our desktop than in this VM.
00:00
If you remember the specs,
00:00
this has around one gig versus my desktop,
00:00
which has 16 gigs of RAM,
00:00
higher frequency CPU, stronger CPU.
00:00
There's a lot of things that go on through.
00:00
Now if you remember,
00:00
when we went to System Package Manager,
00:00
when we came to install package,
00:00
we had that yellow done per resource a few seconds ago.
00:00
But now you can actually see and that being installed,
00:00
here you can get more info in case you want to see
00:00
more informed regarding the product, how use it.
00:00
You have how to uninstall it and you can actually also
00:00
re-install it back in case you have any type of issue.
00:00
You'll see here it's Update,
00:00
Current, Remove information and Re-install.
00:00
It is the current version and this more if you have
00:00
a laptop with very limited resources
00:00
or you have a Netbook.
00:00
Remember those netbooks [LAUGHTER] have
00:00
to face the LEA or a Chromebook for example.
00:00
In this lesson,
00:00
we used Extension Manager to
00:00
install our first application within PFSense.
00:00
This application being Nmap.
00:00
Nmap will assist us
00:00
identify properly devices within our network,
00:00
which will provide us a better idea
00:00
of how to properly secure network.
00:00
In our next lesson, we'll use
00:00
Extension Manager again to install our IPS.
00:00
Hope to see you soon. Have a great day.
