If you are coming from we know some white woman, the way that Lennox represents the major storage devices
will look rather different to you.
So you won't know the scene that defines them has no physical representation of the drive.
Like C, D or E system in windows, but rather has a file with structure starts with sludge at the top
here, uh, or the root here of it.
So this chapter takes a look at how Linux represents two rookie devices, such as hard drives, flash
drives and other storage devices.
But first, look how far additional drivers, drought and other storage devices are mounted upon the
fire system leading up to the root here and root directory monitoring in its context, simply meaning
attaching drives or disk to the fire system.
You know, to make them accessible to the operating system, so for you as a hacker, it's necessary
to understand the finance through the waste management system, but you own your own system and often
the system of your target.
So hackers commonly used external media to load data, hacking tools or even their operating system.
Once you are on your target system, you need to understand what you are working with.
Where to find confidential or other critical files after Mount to drive to the target, and whether
and where you can put those files on your system.
So we will cover all of these topics, so players have to manage and monitor three devices in this lecture.
So actually, I think this lecture will be one or two lectures or no more than two lecture series and
in five system about Linux.
So, yeah, actually, I want to show you an image from internet here.
So we begin with directory known as Dave here DuckDuckGo.
Here.
So we begin with the director known as Dave, which you probably already noticed in the directory structure.
So there is short for device and every device in Linux is represented by its own file within the directory.
So let's start by working with them.
But I firstly, I want to show you the Linux file structure.
Linux fast true here.
Can you see my screen, actually?
Yes, right?
Yes.
So here I want to show you a little representation for presentation for better understanding here.
It.
Actually, it's good to hear.
So I choose two pictures for you here.
So it's opening this film here.
So here, as you can see here, we have the root directory, all of this and all of these folders here.
And we have both.
So as I said to you earlier, all things your Linux is fire.
So we have food directory being there.
It see home leap lost fund media Mont OpEd Spin Serve TNP, we have user, which is the usernames of
our users and we have another local here as well, and we have one here.
So but as written here, what is a system files including kernel being, is binary for Gouzer.
There is.
There is device files and drivers.
Etsy here is host specific configuration.
File Home is user home directories.
Lib is shared libraries kernel modules here.
Our lowest fund is unknown files, so media is here.
Man points for removable media, Monte Mount point for temporary file systems.
We have helped.
Here is optional software packages.
Espin here, name system binaries, etc. We hear data for services provided by the system here.
A temp temporary storage space.
User user applications like source code, images and etc. We have in user.
We have local respin bin and live folders inside.
It did so.
Local is the installer for local users.
Share is config files graphics for user applications.
It's been essential system applications that for user, uh, here and we have been user commands and
lib is shared libraries by user.
So we have.
Lastly, I one title that you is what here.
What we have are run local log tap here.
So we are here.
Valuable data used by the system run is info about current position.
Lock his log files log.
He's log fires and temp long term or large temporary files here.
So we have another representation here as well that I want to show you is a boot.
Here we talk about them and as you can see, we have these shaheem here.
So.
First, I want to talk about this Active Directory here.
So Linux has a special directory that contains file files actually representing each attached to each
attached device, so the appropriate name is the directory here.
So actually lists it.
So we are the top of all file system here, as as we discussed earlier, been built there.
ATC Home Leap like media M.A. Root Run.
If you are using not using Kali or Ubuntu or another system, you yeah, these folders might different
on your system here.
So as as your first introduction navigated the directory, see the view here and elsewhere.
So as you can see here, we have so many folders in it, so I will explain all of this here.
So, um yeah, you should see something like that.
Or let's else L.A. here as we can all in this.
Uh, actually, this is OK.
So as you can see here, we have so many folders in it, Ti here we have um port here and all part port,
uh, PC Alex here.
So I will talk about all of them.
So the devices are displayed in alphabetical order by default.
So you may recognize some of the devices such as c d rom here.
Uh, see the ROM here.
See the room here and we have keep you here as well.
Uh, cause, uh, here, see, Putin may let in Latin see here, so.
Mothers have read in cryptic names here, so each device on your system is represented by a file in
the directory here.
We have brokenhearted, so including devices you have probably never used or even realized and not realized
they exist up to you.
So now they're offering you too.
So there is a device file waiting to be used for it.
So if you scroll down the screen image, you should see more listings of the words of particular interest.
Are the devices starters, SD or SD?
Be here?
Is it like SD, a SDB and other here?
As you consider SD one is to SD 162 SD A1 five actually.
So SD, a SD, A1, SD, A2 and a five.
So which are the hard drive and protections used and used?
B flash drive and special partitions here.
So I am I have not attached was b drive to the system.
So if you attached and use B system, um, I think it will show you SD b here.
So is TB one or two c v two?
So.
How learning sort of since storage devices, so Linux user theological labels for drives that are then
mounted on the file system.
So these logical labels will vary depending on where the drives are monitored, meaning the same hard
drive might have different labels at different times, depending on where and when it's mounted or generally
in Linux represents on a floppy drives.
Remember, there's like it's as if the zero and hard drives as hush the A, so you will still occasionally
see these drives.
Representational legacy a Linux system But today, most prolific drives are gone, and thank goodness.
And even so on.
The legacy that hard drives that use the idea or idea is interface are still represented in the form
of the A.
So a new serial ATA or SATA interface drives and small computer system interface is CSI.
Hard drives are represented, as is the AAA here.
So drivers are sometimes split up into section known as partitions, which are represented in the labeling
system with numbers, as you will see here.
So when systems are more than one hard drive, Linux simply names them cellular by incrementing the
last letter in alphabetical order.
So the first drive is a star, so this means I have one drive because I had I don't have SDB here.
So and the second driver's SDB, if you have, um, UCB and or drivers, STC and so on.
So the serial letter after SD is often referred to as the merger.
No.
So we have the right politicians here as well.
Now let's look at actually.
So I will stop with you here.
Uh, so I'm rating you in this lecture.
