Welcome back to the savory course in building. You're in for a sec lap. I'm your host and instructor, Kevin Hernandes.
00:06
In the beginning of the court, we started planning how to build our lap would look a different technologies, tools, et cetera, to incorporate into the system that we're building up to that point, we consider only the hardware requirement off the tools and the features they offer.
00:22
In today's lesson, we're actually going to do a network diagram off our lap. How we gonna interconnect
00:28
the different devices that we're gonna be using in our lab?
00:34
Now let's get started as we have utilized mostly free tools or free variants of tools for our laps will also be utilizing free tools in order to make our network diagrams.
00:46
I understand that there's product out there, such just Microsoft be CEO
00:51
that you might have access to, and you're more than welcome to use the software if you wish to do so. However, for those that don't have options, Daryl dot io is a very good tool and free of charge,
01:03
one of the key elements and features that I really appreciate it out of this application. It so I can open and create a dark room on my death. Stop.
01:11
Save it, e mail it to myself, open it in the Web browser and continue from there when I'm undergo.
01:18
Also, it works pretty well. Cross platform from Mac
01:22
two windows. And if you're in linens, you can also use the browser.
01:26
No, let's go ahead and create a new diagram.
01:30
Yes, you can see you have several options. You have business.
01:34
You have some type of charts
01:37
engineering diagrams on. Of course,
01:40
we got network, so let's go ahead and create one
01:44
networking. Now which one? You pick its base under preference, right? And we might actually be required to create several of thes.
01:52
You can see this this map itself.
01:55
It's more targeted towards wireless excess devices, while this is more towards feelings, so it's actually opened up so you can see them a little bit better. See Internet fire well, wireless access point and then all your systems connected to it.
02:10
Now let's go ahead and open a new one, see what other options we have,
02:15
creating a diagram
02:17
network.
02:19
Now let's pick this one with pretty colors.
02:23
See what it is. Okay,
02:24
it's more like grouping.
02:28
So this one, it looks a little bit complicated. But at the same time, this
02:34
well, more properly. Percent what we might be required from our network, as with skin, for example, repurposed ISS and say, for example, this will be our webcams. This would be our applications. It will be our, um,
02:47
beater game console to center. Right. So this is not a bad example to you to lice.
02:55
Let's go back to network and see what other options we have.
03:00
You can go obviously, like a more classic route such as this,
03:05
right?
03:06
It's most likely why you're familiar. I switch if you has worked with diagrams that work.
03:14
And we're also open the last one on the left.
03:17
So this one, um, doesn't look that bad. Actually,
03:22
it's organized. You do have the router. So this one is very high potential candidate for what we're looking to do.
03:29
So now we have two strong candidates for a network tagger. Now, here's today, right. We have to do two types of drawings. The 1st 1 will have to be our current network infrastructure, and the 2nd 1 are expected, or what we really want to accomplish
03:47
from our new network.
03:49
Now let's properly look at our network.
03:53
If you, for example,
03:54
have a wireless router. So just this one.
03:58
You have all your systems and the firewall.
04:01
He will look not so different from this. Actually
04:05
here.
04:06
Current home might look more like this where the firewall
04:11
is included as part of here,
04:15
modem or router, right,
04:16
and therefore
04:18
very limited. Or when you do end. Yes. Humor, for example, could have this as a wire connection
04:26
instead of wireless
04:29
right here.
04:30
But at this and the end of the day, most home networks are not that different from this.
04:38
So based on this, let's start building what I currently have in my environment.
04:43
I encourage you to do something similar as we move along.
04:47
Now, before we start drawing or pretending, we know exactly how our infrastructure is internally, Let's try to use some tools to help us with this.
04:58
Let's go ahead. Open. Google looks for and map for Windows.
05:03
Okay, let's go for
05:08
here. A map,
05:10
right? And let's look for a very we can always use for Windows.
05:17
It also actually included in it, so let's go ahead and download it.
05:24
You can sit sound living right here in the bottom.
05:27
Let's go ahead and install it. A swell.
05:30
A map installer? Yes. Disagree.
05:34
Okay, so here's set him up.
05:39
Stolen fault
05:42
referred to extract.
05:45
Uh, says the MP cup. It's already install, but that's over, right? It just in case
05:49
is N P Capital
05:58
and this way for it to finish.
06:00
Obviously, you don't necessarily need this, but I'm just gonna go with thes option first and then show you alternatives off what could have been accomplished without the installation of this tool. So it looks like it's already installed. Let's go ahead and open it.
06:15
And two,
06:19
it's opening here on the side. So let's move it along. Now there's different scan options here, right? So you have Internet intense scan
06:30
UDP right? In this case, I wanted to a ping scan just to see what's out there,
06:35
right? And I select that
06:39
now, before we start any skin, we gotta make sure
06:44
that we have all our devices and virtual boxes and systems and tools. Whatever you want to call them up and running, Let's put our network reach
06:55
and here we go, right.
06:58
Let's go ahead and hit skin.
07:00
Now, this will take a little bit of time, but it's not gonna be that bad. Okay,
07:05
here we go.
07:11
Right. Oh, my God did not intend to do that, But let's keep it like that.
07:15
This will be the equivalent off our techs. Right? So let's look for text Texan here on labels.
07:23
Here we go.
07:25
And
07:26
in reality, if you think about it, anything that comes from here right
07:30
here and we will have let's say
07:34
sorry some of this up,
07:36
who will be our curator.
07:41
All right, You say it is this
07:44
being where but
07:46
here it will be.
07:49
Are
07:54
pf since
08:00
and here will be
08:03
all right before
08:05
as such. Okay,
08:07
and this is give or take our current
08:11
that were No, this is like a sort of currently out
08:13
even know we do have, like a is a physical Very you're not a logical pretty much flat if you want to be honest. But here's where things come through, right.
08:24
Here's where you have to start planning
08:28
and this is where paint comes true. Go ahead
08:31
and do
08:33
this for a solid color put like colors. And right now we're gonna have here
08:39
and little box,
08:46
Two boxes.
08:50
Three boxes
08:58
for backs is give or take. And another box here,
09:05
Give or take. Right? And why do I want to do this like this? Well, there's different aspects that we want out of the network and where we're gonna be programming to vigilance. You have to be really careful how you want to do this room. Half eight switches or eight ports in our smart switch. Right. So we have 1234
09:24
five little boxes here.
09:26
That means we have alone
09:30
three more that we can. Actually,
09:33
that stuff too,
09:33
if we wanted to. And Sorry, I have a line there.
09:39
So
09:41
here you go
09:43
that you're gonna have a little brown here
09:46
and it doesn't mean we're gonna use them. It's just that the options are
09:50
here
09:56
367 and obviously one of them, it's not going to really be used because it's the one that's gonna be connected it out. Actually, two of them might not be used at all. So there we go. Now
10:09
let's go ahead and actually used text for now
10:13
and say Desist! Our
10:16
That's really big.
10:18
Here's 26
10:20
modem flash. I speak right
10:24
And that's gonna be the first day
10:28
it's gonna come
10:31
right here.
10:35
All right? Just leave that
10:37
sorry.
10:39
Yeah, you know, how do you want accomplish this? It's really important. First of all,
10:46
say
10:48
what Words for everyone to put different things. For example,
10:52
I want to have cameras, right? And one division.
10:56
Right.
11:03
I want to have actually put cameras down here,
11:07
and this one will be my servers. Right. Which entitle curator
11:20
Splunk kelly
11:24
it and sift.
11:26
Now, I also want one specific Bach for my firewall.
11:35
Right.
11:39
In this case,
11:41
they're gonna pick pf sense.
11:50
All right,
11:52
then we're gonna have since this is green,
11:54
let's say this won't be my wireless, right.
11:58
So it would be my math book.
12:07
It will be my phones, for example,
12:13
In the isis,
12:15
I think it must be the X box on desktop
12:20
Thank you
12:20
station if you want to put PlayStation
12:28
okay.
12:33
And just in case in this other box, And I have a high security
12:39
tight security,
12:43
right? And you have are explainable boxes.
12:48
Praetor
12:50
right there.
12:54
The recent is we want to make sure that the rule for this sport for this role in the far wall
13:00
is toe on Lee. Allow connection from Cali
13:05
to it.
13:05
That's it.
13:07
And you know, if you make sure that on Lee, for example, our wireless devices in this case Mac book can access
13:13
this area, then we should be pretty much. Now let's start drying this and drop dot io.
13:20
So let's go ahead and open a new Gregor and we're gonna select link diagram so we can actually learn to use this tool better.
13:28
Now, we do have several options here. You can see a halfs. A few of them pick.
13:31
However, you can always come to more shapes.
13:35
Example Clip arts Really good. Like the new design of systems
13:39
and you can check it and you could see 1/2 Also, Cisco devices, Citrus of Isis and network checked
13:46
hit a plane,
13:48
and you can either expand these
13:52
right
13:54
such,
13:56
or you can also search here in the top, for example, Internet.
14:01
Right.
14:03
You have a little cloud here for the Internet, and we're actually gonna utilize this and I'm drunk.
14:09
Now that we have our clout, let's add a modem, right? First thing, always Internet, there will be a motive. So let's cut it here,
14:16
drag and drop it.
14:18
And one thing you can do is you're gonna actually select the arrow and then connect that straight to the modem as such.
14:26
No, we have a modem at our switch.
14:33
Let's utilize this one.
14:37
You're such
14:39
okay?
14:41
That's at some little rectangles here
14:45
for our areas, right? Or violence
14:52
at two of them.
14:54
You know, the other thing we're gonna do is we're gonna add some style to it.
14:58
That way, it's easier
15:01
to know them. Okay,
15:03
No, let's make sure to connect them,
15:05
right.
15:05
The moon is gonna connect directly to the switch trick, and in order to help us, we're gonna say it's gonna connect. Port one is very important as we there are dragons. And as we're starting to also to sign our lab,
15:22
you're gonna be assigning dealings, right? So for this refer any outside interference
15:26
earned a villain.
15:28
Okay.
15:31
Afterwards, we're gonna connect right to our firewall.
15:35
So
15:37
just looking for a far wall.
15:41
This one looks pretty good.
15:43
Mmm.
15:46
Pf sensory.
15:48
That's such You're gonna connect them together,
15:54
such
15:56
area,
15:58
and we're gonna sign this
16:02
poor too.
16:04
That's Africa.
16:07
The last thing is
16:10
you gonna look for a desktop,
16:14
right? and we're gonna pick one.
16:18
Sure, it's one that looks futuristic like thes one frank somewhere
16:22
area that looks good.
16:25
Let's say this goes here, right?
16:30
Let's connect them
16:33
and let's call it Port eight. Inner scenario. Okay,
16:38
for now, we're going to keep the throwing at this level because we're gonna be adding it as we move alone and integrate more and more things. The first of us, I said, Is it gonna be connecting pf sense into it? So what we learned today, we basically started developing a network diagram for our lab. Was our connecting the dots
16:56
looking into tools, shares the same map
16:59
and draw that Io in future lessons will keep expanding this as well. Let's start incorporating and connecting our lap up to see you soon.
17:07
Have a great day.
