‫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.
