Hey, everyone, welcome back to the
course. So in the last video, what
we did is a quick acknowledgment and
so again, we just ran that against
our server IP address.
Now, what we're going to do with
this video is we're actually going
to go change some Windows
firewall settings and then we're
going to run a scan against it.
Now, one thing I want to mention in
advance is once we make this
the setting change and may kind of
lock up the virtual machine.
And so we'll want to reset it before
we move on to the next lab video
so we can complete the task in those
labs. So just FYI on that is
something I discovered during
testing, not a huge issue where,
you know, if you've ever worked with
virtual labs environments
in the past that you know or hosted
or something, you may have little
glitches like that and that's
perfectly fine.
Ah, so let's go ahead and get
started. So the first thing we're
going to do is actually connect to
our server machine.
So the pilot C0 wants
to just go ahead and click on that,
a setup machine there.
You can minimize this control
panel here for the example.
We can minimize that down.
And then what we're going to do is
we're going to search in the start
menu, so we're going to right click
on the start menu. We're going to
search for firewall dot kpl
and then basically just click OK, or
hit the keyboard and that
will go ahead and pull up the
windows firewall for us.
So we've got to right click,
go to search and then do
firewall up
excuse me, we're going to go to run
click on the wrong one there and
we're going to do firewall dot
CBl all lower case.
And then again, you can either click
OK or just enter your keyboard
and you'll see it'll pull it up for
us here.
Ah, so our next step here going to
click here and step six, we're going
to click where it says Turn Windows
Firewall on or off.
So it's right here on the left side
of your screen.
And then it gives us some setting
options that we can change.
So what we're going to do now, we're
step seven, is you're telling us
that we're looking at this particular
screen in the background there.
So now what we're going to do is
we're going to under this top box
here. We're going to check the box
next to block all incoming
connections, including those in
the list of allowed apps.
And then so we're going to put that
checkbox right there and then we're
we're we're going to do here at this
bottom box is click the turn on
Windows firewall and then check that
same type of type of block
right there.
So that's all we're going to do
here. So those are the two setting
changes that we have in steps eight
and nine.
And then we're just going to click
OK to see the changes and we're
going to go back to our Windows time
machine and then just run our
same acknowledgment scan that we did
earlier. We're going to run the same
command again.
So let's go and do that.
And we're just going to say, OK, to
that, go back to our
Windows 10 machine.
And if we stayed on this server
machine, we would see probably an
error message here in a moment.
But we don't care about that.
We just care about coming back here
and running our command
so we can type in this command again
if you want to.
The easiest way to do it is just
press up arrow on your keyboard
and you'll see it'll pre default.
All the information we just typed
for the last command we typed in
there for us.
And if we went, you know, if we did
the up arrow some more, we could go
back to the previous command, et
cetera.
So here's our command here.
All we have to do now is hit the
entertainer keyboard and it'll go
ahead and run that command.
Now, as I mentioned before, it takes
a moment or so to run this.
I'm going to pause the video briefly
and once it comes back up with
results, I'll go ahead and start the
video again.
All right, so we see that I have my
results on the screen again, if you
haven't gotten your results back
from the scan behind the video,
just wait until you get your
results.
But we have one question we want to
answer here in our lab documents.
So now if we're looking at Port 80,
is it showing us filter on filters?
If you remember before it showed us
unfiltered.
So let's take a look at our outputs.
We see again, the second line from
the bottom there we see that it's
now showing as filtered.
All right, so if you think back, we
changed Windows firewall setting, we
actually turned on Windows firewall,
so now it's filtering stuff through
that particular firewall in the host
machine there. And that's why we're
showing filtered as our output
here inside of Calli Linux.
So in this video, we just made a
quick firewall setting.
We basically turned on Windows
firewall and then we went ahead to
run another acknowledgment scan to
see what kind of difference we had
gotten in the results.
And we noticed that now it's showing
us filtered, which makes perfect
sense because we just turned on the
firewall.
All right, so we're going to continue
on in the next video with additional
scanning lab.
