>> Welcome back to a server recourse
00:00
into building your InfoSec lab.
00:00
I'm your host and Instructor, Kevin Hernandez.
00:00
In a previous lesson, we looked at
00:00
the different hardware requirements
00:00
>> at each of our tools,
00:00
>> application software required in
00:00
order to build our InfoSec lab.
00:00
In today's lesson, we will be looking
00:00
into different selections of hardware in order
00:00
to pick and choose
00:00
the configuration we most likely will end up having.
00:00
Now, let's take a quick look
00:00
at a sheet we prepared in a previous lesson.
00:00
Here you have firewalls,
00:00
proxies, SIEMs,
00:00
ESXI, pen-testing labs,
00:00
forensics, and after directory.
00:00
Now, one very important thing is,
00:00
if you recall correctly,
00:00
some of these overlap with each other.
00:00
Specifically, the firewalls.
00:00
Next-gen firewalls such as pfsense,
00:00
IP fire and untangle,
00:00
all of them had features that included web proxy,
00:00
included IPS and IDS.
00:00
Therefore, for IPS we will not be
00:00
using to build on our InfoSec lab
00:00
for this exercise we'll be planning here,
00:00
and neither will we be using web proxies.
00:00
Now, let's look at these configurations, right?
00:00
And let's add them up. First of all,
00:00
we need a CPU around one gigahertz here.
00:00
For the SIEM, we are going to be
00:00
needing approximately two CPU cores.
00:00
It says that it's two physical CPUs but in reality is,
00:00
CPU core will be more than enough.
00:00
So technically we'll be looking
00:00
at three cores give or take so far.
00:00
Lastly we have ESXI,
00:00
which recommends two cores as well as the Pentax,
00:00
forensics and Active Directory.
00:00
Theory you will need a CPU that at least
00:00
has four cores preferably eight.
00:00
This will be our baseline for a CPU perspective.
00:00
Regarding to hertz,
00:00
don't worry too much about it, most modern day CPU's
00:00
have two-three gigahertz
00:00
so you should be fairly okay with this.
00:00
In regards to RAM, you have around
00:00
two gigs right here, from this application.
00:00
When it comes to SIEM, you have
00:00
eight, and when it comes to ESXI, you have four.
00:00
So to keep things simple,
00:00
we're going to say we need
00:00
>> around 16 gigs, give or take.
00:00
>> So eight, plus four, plus two,
00:00
plus one, plus one, right?
00:00
We're going to say we need 16 gigs of RAM minimum.
00:00
[NOISE]
00:00
However, I will recommend at least,
00:00
>> 32 gigabytes of RAM.
00:00
>> If you're planning to add all of these systems into
00:00
one computer and regarding to storage, right?
00:00
>> What will we learn for storage, is add up
00:00
the different storage option looking at
00:00
the highest tool of each application.
00:00
You can certainly see, you will need around
00:00
two terabytes of storage,
00:00
if you're planning to put all these applications.
00:00
However, taking consideration the size of your network.
00:00
>> Being a small network,
00:00
I don't really expect
00:00
a Splunk curator to need over 110 gigabytes of storage.
00:00
It really depends on the amount of systems.
00:00
If you're not generating too many logs, curator
00:00
itself wont be using too much storage,
00:00
you will use this application, logs, and basically,
00:00
the logs of the systems
00:00
for everything integrates into it.
00:00
>> So if PFSN uses eight gigs and curator uses a
00:00
110, and you look
00:00
the ESXI uses eight,
00:00
>> even though I didn't write it here.
00:00
>> Well, already scanners are around
00:00
20, and every other OS type it's around 20, at least.
00:00
You've clearly say that you need three-four OSs, right?
00:00
So that's 80 gigs plus a 100 gigs.
00:00
>> So you're looking around 250 gigs total for storage.
00:00
>> Right?
00:00
>> However, I will recommend a little bit
00:00
more depending on your network size.
00:00
One big consideration is using
00:00
solid state drive in order to
00:00
make these a little bit faster.
00:00
Now, like I mentioned before,
00:00
depending on your system,
00:00
you might require a dedicated computer just for
00:00
SIEM, and take that
00:00
into consideration when building your system.
00:00
Now, how do we go about building, or creating a system?
00:00
Let's go to the Internet for that.
00:00
>> First of all, let's
00:00
look at computers that are already out there.
00:00
>> This is more for someone
00:00
>> who has a little bit confident,
00:00
>> that doesn't mind doing its own upgrades.
00:00
>> You can look into a Dell micro PC.
00:00
>> This is what I searched in Google.
00:00
Now these themselves, you can see start at around $100.
00:00
It might be missing a couple of things.
00:00
You've got to make sure you read through the system.
00:00
For example, we have a 4500 system over here.
00:00
We have a 3400 system, and we
00:00
have most likely these V0
00:00
little bit older being the cheapest one.
00:00
But let's click on it,
00:00
scroll down and look at the CPU itself.
00:00
What type of CPU it has attached to
00:00
it, or it's been using and you can see it's a Pentium.
00:00
So in reality it's not a old processor,
00:00
but it's still not as powerful as ICore.
00:00
I prefer for a $100
00:00
plus it does not incur the AC adapter.
00:00
I remember buying one of these for
00:00
maybe around $10 on eBay and works pretty good.
00:00
It's not that bad, I'll be honest with you.
00:00
Intel pentium is not
00:00
a bad processer, and if I will buy this,
00:00
I will most likely use it specifically for the SIEM.
00:00
Now, one thing is once you get in here,
00:00
you might be looking at other systems
00:00
down here that include,
00:00
for example, hard drive, et cetera.
00:00
Right here you have a little beefier CPU.
00:00
You can just click on that, and see more details.
00:00
>> Here you have the same G 3250 with a hard drive,
00:00
and 500 gigabytes of storage, sorry.
00:00
You have four gigabytes of RAM
00:00
versus the eight gigs of RAM here.
00:00
>> So it really depends if you have a spare drive.
00:00
You might just want to go ahead
00:00
and buy this one over here.
00:00
If you don't have either,
00:00
then you might want to buy the other one right?
00:00
Now, let's say you
00:00
want to build something a little bit newer.
00:00
So here for you actually start picking
00:00
up the generations, right?
00:00
You go seven generations CPU, right here.
00:00
>> You can see the prices are a little bit
00:00
higher, but here you have a $7500.
00:00
This is a fairly recent CPU,
00:00
maybe two years, three years old.
00:00
So it's not an old system at all.
00:00
And this was more if you want to
00:00
have one system to do it all.
00:00
Now, Dell is not the only option you have until snug.
00:00
This is a similar approach.
00:00
Basically, all it has is a CPU maybe,
00:00
and you will have to plug in the
00:00
RAM on the storage yourself.
00:00
In the other cases like this one, right,
00:00
which is a sponsor at,
00:00
it will have everything integrated,
00:00
and most likely all you have to do,
00:00
it's put the OS in it, but be aware,
00:00
you might need to troubleshoot these STR, eBay systems.
00:00
The last use system I would recommend is
00:00
star bricks gigabyte, and he said
00:00
also sort of bare-bone system.
00:00
So you might need to put RAM,
00:00
you might need to put storage on them.
00:00
So keep that in mind when you're building this.
00:00
Specifically, if you're not
00:00
comfortable when building your own system.
00:00
Now let's take a look into
00:00
buying something already pre made.
00:00
I went in to Best Buy here,
00:00
and I looked at desktops all in one systems, right?
00:00
A look at systems between two hundred and fifty,
00:00
a hundred and forty nine dollars.
00:00
Now one thing that's crucial
00:00
when picking up some systems,
00:00
it's how old the CPU is.
00:00
In this case, we look for seven gen, eight gen CPUs,
00:00
and AMD Ryzen series, right?
00:00
First, second generations are pretty decent enough.
00:00
You can also pick sixth generation intel here.
00:00
And then I sort by price, low to high.
00:00
>> And here you can see a rise in three series.
00:00
>> Not bad, pretty decent.
00:00
This is similar to I3 when you're looking,
00:00
comparing CPUs but if you want to go with,
00:00
I5, for example,
00:00
you have this one over here,
00:00
twelve gigabytes of memory,
00:00
two terabyte hard drives,
00:00
ACER and pretty much all you have to do in this system
00:00
is install the OS, and that's it.
00:00
So this is not about system
00:00
overall, and you most
00:00
likely be able to put everything on it.
00:00
Now let's say you want to build your own system.
00:00
>> What do you need to do? Well,
00:00
I like myself going to
00:00
PC part picker and go into System Builder myself.
00:00
Here, I can choose the CPU and I can, for example,
00:00
select something that's a generation older or recent,
00:00
right? And add it.
00:00
>> What I like about this is once you add a CPU for
00:00
example, and let me
00:00
hit back, so I don't need this because it brings one.
00:00
You can then see the type of
00:00
CPUs, and you can sort by price.
00:00
You can start building a fairly
00:00
>> decent system like this.
00:00
>> One thing I recommend is looking at these numbers.
00:00
For example, you always,
00:00
even though it has comfortability,
00:00
in at least with AMD Ryzen,
00:00
you need to make sure you look
00:00
at these higher numbers that way you don't have to
00:00
be flashing the bios.
00:00
Go memory, right? In this case,
00:00
we said 16, give or take.
00:00
But let's see what else we have here and it seems
00:00
16 is the highest this motherboard
00:00
supports. So let's add that.
00:00
Again, I'm just showing you how to use this.
00:00
It's not necessarily a good setup.
00:00
It's just a give or take. So you can see how
00:00
much the system like this will cost.
00:00
This case, I will go with a 100 gigabytes storage, SSD.
00:00
So you can come here
00:00
SSD and one thing I like to do when it comes to SSDs is
00:00
go through the price per
00:00
gigabyte and that way you can get
00:00
a fairly recent decent deal like this E-data.
00:00
I've used E-data on the past and it is pretty decent.
00:00
However, if you want to go something a little
00:00
bit more recognized,
00:00
you can just keep scrolling
00:00
down until you see a match to,
00:00
for example, USA base, $53.
00:00
That's not bad. So you can add that in there.
00:00
You don't really need a video card.
00:00
You do need a case,
00:00
you don't need a power supply.
00:00
So in this case, go with what
00:00
>> you like or what's cheaper.
00:00
>> Let's go below because of the wattage.
00:00
Let's select the power supply.
00:00
I prefer coarser itself.
00:00
I'm not going to look for something
00:00
else and let's see the details below.
00:00
Basically it's not compatible.
00:00
So you've got to be careful with this.
00:00
And here you basically have everything now,
00:00
you're looking around $453, give or take.
00:00
But if you remember the ACER,
00:00
yeah, it's for $446,
00:00
but it's not an SSD.
00:00
So to take into consideration building your system,
00:00
obviously here you're getting some data
00:00
that might be a little bit newer,
00:00
but still be able to configure it.
00:00
In my case, all we going with
00:00
a system very similar to this one,
00:00
they are a bit complex and I'll be
00:00
showing you how it is in the inside.
00:00
What have we learned today?
00:00
>> We looked at different hardware
00:00
options for our system, right?
00:00
>> We looked at new systems,
00:00
right? We looked at best buy.
00:00
You know what we're referring to, but still fairly new.
00:00
You don't have to touch it. You do
00:00
not have to be configuring it.
00:00
>> We looked at used Ebay systems.
00:00
>> We looked at building your own system and we have
00:00
considered are mentioned in the past
00:00
upgrading your system, right? Adding RAM.
00:00
Basically it's the biggest difference in here.
00:00
Also maybe changing and I'm adding an
00:00
SSD will greatly help with that performance,
00:00
especially at the current proxy.
00:00
So you can able to get a one terabyte for $80,
00:00
give or take, right?
00:00
So it's not a bad option.
00:00
Now in our next lesson,
00:00
we'll be looking at the networking hardware
00:00
we will require in order to make this left function.
00:00
I hope to see you soon. Have a great day.
