All language subtitles for 4 - Lab Overview English

As I mentioned,

this course is going to be highly practical.

Therefore you will need a lab,

a place where you can practice and experiment

with the things that you're going to learn in the course.

Not only that,

but having a lab is essential for hackers or pen testers

because let's say you discovered a new attack

or you want to experiment with a new attack

or you learn something new online, and you want to test it.

Then the perfect place for you to test this

and practice hacking is a hacking or a testing lab.

Now to create a lab,

you just need the number of computers with different

operating systems and you will need a number of networks

if you're testing network attacks.

And if you're testing website attacks,

then you will need to install websites on these computers.

Or you can do all of this inside your computer,

inside one machine and install everything else

as virtual machines.

And this is what we're going to do.

So let's say you have your computer right here.

This is your main computer that you use every day

to check your emails or even to watch this course,

this computer might be running Windows or OS X or Linux,

it doesn't really matter, it can run any operating system.

You can keep all the programs that you love and like,

and install a virtualization software such as virtual box,

or VMware, a virtualization software,

allow us to create a number of virtual computers

inside your main computer.

So we can have three or four or five or 10 computers

all installed inside your main operating system,

inside your main computer.

The really cool thing about this is you will not need

a number of computers.

You can do everything inside a single computer.

So what we're going to do

is we're gonna have a hacking machine.

This is going to be the machine that we will use

in order to hack into other machines.

We're going to install Kali Linux on it

and we'll talk about what that is later on.

And we're going to have two target machines,

these are machines that we're gonna try to hack into

and practice hacking against.

One of them is gonna be running Windows

and the other one is going to be running an operating system

called Metasploitable

and we will talk about that once we get to it.

Now it is very important to understand

that you will not lose any functionality

when you install an operating system as a virtual machine,

you can use that machine exactly

as if it's a real physical machine.

So the really cool thing about using virtual machines,

first of all, you're not gonna lose any functionality.

Second, all the machines are going to be isolated.

So as we go through the course,

we're gonna be trying to hack into these machines

and we might actually break one of them, but that's fine.

It will not affect your host machine.

You will be able to easily fix this and go back

to a snapshot of when the machine was working

without affecting your main computer.

The other cool thing is that you'll be able to have a number

of different versions of each these machines

and you'll be able to change the configuration easily,

change the network settings,

or switch between different states of these machines

and so on.

So by using virtualization,

you will not lose any functionality,

but you will gain so many cool features.

And the main thing to keep in mind is your host machine,

your main computer will never be affected.

It's completely isolated.

And if we break any of these machines,

nothing will happen to your precious computer

that you use every day.

And this way you can always use your host machine

for daily use, for checking emails, watching the videos,

doing whatever you do normally,

and then use your virtual machines for hacking

and practicing the attacks.

And this is what we're gonna be doing in this course.

So right here,

I have a Windows computer

that does not contain any hacking tools.

So I can't really use it for hacking,

but I have a virtualization software called VMware

installed on it.

And this software allows me to run multiple

operating systems as virtual machines

within this host computer.

So I can use the host computer for my data use

and then use the virtual machines

for whatever use I want for testing or for hacking.

So if I zoom in here on the left,

you can see that I have a Kali Linux installed.

This is an operating system that we will use for hacking.

You can see I have another windows computer.

You can see that I have Linux.

All of it installed as virtual machines,

and then we're gonna be using these

as we go through the course for hacking

or for testing without affecting

our main host operating system, this windows computer.

Now don't worry about any of this,

in the next lectures I will show you in details

how to install this virtualization software, VMware,

on all of the major operating systems, on Windows,

Linux or Apple macOS.

As we go through the course,

I will also show you in details

how to install these operating systems

as virtual machines within VMware.
