Okay.
Let's talk about what is virtualization.
So virtualization is essentially when we take one host or computer we can run multiple or different
operating systems on it.
Essentially we can have say a windows host running in Linux, Chrome OS or Apple potentially.
Or we could have an Apple run Windows and Chrome, Linux and so on and so forth.
It allows us flexibility to run machines that are essentially a virtual machine.
It's a virtual computer running off our host computer.
So this comes in really handy because it allows us to have a self-contained computer outside of our
main computer.
So some um, programs out there that will run this is OS X, parallels, VirtualBox and VMware are some
examples, and some of these are free and some of these are going to be paid VirtualBox for example,
is free.
And there's also the Mac uh, GitHub uh, which I'll explain in a minute.
So by using our existing memory, CPU, and hard drive space on our host computer, we can run a again,
a virtual computer.
It's a it's its own system.
It doesn't really see our host computer.
It thinks this its own machine.
It thinks it's actually thinks it's an actual physical hard work computer.
So some reasons why we would do this is that running the virtual machine, if our computer gets blown
up, our virtual machine gets blown up by virus, malware, things like that.
Again, it should be self contained, meaning that it's not going to affect our host computer.
There's not a lot of malware out there that will jump from a virtual machine to a host to the host computer.
Uh, there are some examples of those out there, but for the most part, if you get a virus on your
virtual machine, it's going to stand your virtual machine.
Also, again, it allows us the flexibility to run multiple operating systems.
I can be running a windows machine, or it could be running a Linux machine or OSX machine, and I could
have that Linux distro.
In this case it's going to be CSI Linux running on it.
So that's going to be really useful.
And also, if something happens to that virtual machine, we get a virus, it gets corrupted.
Um, I want to have a clean machine when I start my investigation.
It's really easy.
I get I can revert back to a snapshot, which will take a look at when we set up a virtual machine and
it's going to be a clean computer.
I can have a clean computer every time I run it.
Unlike if I am running an investigation, my host computer, something goes wrong.
I got to wipe out my machine.
I have to reload windows or reload the Mac or Linux on there.
Load up all my programs again.
It's going to.
It's a big hassle.
Whereas a virtual machine, something happens.
I just revert my snapshot if I need to turn over that that computer for evidence.
For example, if it's going to a court case or a police or something like that, instead of handing
over my host computer, I could potentially take that virtual machine, throw it on a on a external
drive and hand it over to law enforcement, hand it over to the lawyers and whatnot.
And they have that machine.
They can actually run it on their own host machine and take a look at everything that I've been working
on.
So that's another advantage of virtual machines.
So in the next video we're going to actually set up VirtualBox.
Thanks for watching I'll see you next video.
