What's Ethical Hacking?
The term "hacker" is withal utilized by mainstream media and popular culture to relate to some of those endeavoring to gain access through certain security protocols. In other words, the media depicts the 'hacker' as a malefactor.So Since 1995 The Term "Ethical Hacker" Was Engendered To Obviate People Form Mixing Up The Benevolent Good Guys With Lamentable Bad Ones.
Ethical Hacker is a computer security expert who investigates strategies to crack protections and expose susceptibilities in a computer system or network,Who works to keep data secure from other assailants by identifying contrivance bugs that can be ameliorated.The Process Is Called "Ethical Hacking".
Ethical Hackers are typically utilized by the owner of the goal system and are conventionally paid (sometimes very well) for their work.
Their work is not illicit because it is performed with the sanction of the machine owner.
Why Linux ?
First of all, Why Linux? There are a number of operating systems and software, among those, why Linux ? Why? Why world?.
Begins to sound rather like a philosophic topic.The Reason Behind The Fact That Almost all Ethical Hackers Favor Linux Over Windows Or Any Other Operating System Is Because Linux Is Open Source, So An Average User Would Have Plenty Of Freedom Over System, Most Hacking-Pentesting Tools Are Designed For Linux As well as Linux Seems To be more Stable And Lightweight.(Most Lightweight Linux-Distros (Handpicked) ), You Can Even Use Linux In Your Phone In Different Ways And the capacity of the Powerful Linux terminal is just amazing.
1.What Is Linux? /Who Owns Linux / Who Made Linux?
Linux Is A Open Source, Unix-Like Operating System Made By Linus Torvalds.Who Also Made Git & Subsurface.
Since, Its Open Source anyone can see-edit, distribute it. The Linux kernel is Licensed Under GNU General Public License The kernel not the OS, is Linux.
When the GNU project concretely engendered a consummate framework, one of the final apertures was filled by the Linux kernel.
People call Linux an operating system because to relate to the entire framework - system, so they just call a name-designation.
Note : Linux Is The Kernel Not The OS
Popular Linux Distributions Are Fedora, Debian, Ubuntu, Kali Linux, Popular Desktop Environments Are GNOME and KDE.
Anyone Can Downloaded The Linux Kernel Form https://www.kernel.org/ .
Many People-Consumers Use Linux Without Even Knowing It.Wait,Will Linux Ever Rule The World?
2.What Is The Linux Kernel?
As Mentioned Earlier Linux Is The Kernel Not The OS.The "kernel" is a computer program at the core of a computer operating system which has absolute control over everything else in the system.
The homogenous kernel is the operating system infrastructure where the subsisting operating system functions in kernel space.The Linux kernel is a free, open-source homogenous, customizable kernel engendered in 1991. It is utilized in a wide range of computing systems. Most of the Linux kernel code is indited to the traditional C language
3.What's Sudo?
Sudo Is Like A Program which sanctions users to run programs that have the security sanctions of some a superuser. As way of comparison to the homogeneous command su, users must provide their own password for sanction. It can additionally be implemented to control arguments or several injuctive authorizations to be passed.
Sudo is often utilized for administrative tasks.
4.Where is Linux used?
Android the mobile operating system is based on a modified version of the Linux While A lot Servers Use Linux,According To Wikipedia [1] over 96.4% of the top 1 million web servers' operating systems are Linux, 90% of all cloud organizational fundamental facilities is powered by Linux including supercomputers and cloud providers.
Linux Like Other Operating Systems Are Utilized For Day To Day Activities, Writing-Compiling Software, Playing Games, In This And The Other Following Articles We'll Talk About Mainly Utilizing Linux In Cyber Security For Educational Purposes.
5.Is Linux And Unix The Same Then?
Linux Isn't Genuinely Unix.Linux is a kernel but its not exactly an OS. Linux Can Be Called A Group Of Open Source Unix-like operating systems depending on Open Source, Customizable Linux kernel.While Unix is a category of different operating systems , Unix Commenced At Bell Labs.
Modern Linux Distributions Can Be Called Unix But at the same time they're not UNIx.So ,instead they are Unix-like Predicated On Linux Kernel.
Fun Fact : The Linux Kernel Is Written In Mostly C and C++
6.Basic Linux Commands :
Command - - - - - Action.
ls List All Directories In Current Path,
To See Hidden Files add command line flag a (e.g ls - a)
pwd List The Current File Path Your In.
cd Change Directory (e.g - cd Filename).
mkdir Create a Directory (e.g - mkdir Filename).
rmdir Remove An Directory (e.g - rmdir Filename)
cp Copy File (e.g - cp file.txt path/txts/stuff/)
mv Move File (e.g - mv file.txt path/txts/stuff/)
touch Create File (e.g - touch abc.sh)
locate. Find Something (e.g - locate file.txt)
Fun Fact : the command sl, summons a ASCII train and the command cowsay, summons a cow
7. What Are Package-management Systems?
Basically, Package-management systems are mainly software that helps to install other new software and tools, different Linux Distributions have different package management systems.(e.g RPM, Snappy, dnf, aptitude, yum)
8.What Is Bash Shell?
Bash is a Unix shell and a scripting language.It's Used In A lot Of Linux Distribution.There Are Lots Of Things Which Can Be Done With Bash,Form Writing Scripts To Automate Tasks Or Ethical Hacking Tools.
The Basic Syntax Of A Bash Script :
| get_name() {random number = 8shell = "bash" echo ${random number -5} echo "Hello World" }echo "$(get_name)" |
9.What's Daemons?
The daemon Is a computer program that is utilized as a shadow, instead being under the direct control of an immersive user in multi-tasking computer systems.They control the network, directory systems,etc.
10.What Is The Linux Terminal ? Is It Possible To Use Linux Without The Terminal?

A command-line interpreter or command-line processor is the software that controls an interface.
Operating systems use a command line interface for interactive access to features or resources of an operating system in a shell.But With Many Linux Distributions It's Possible To Not Use The Terminal At All Instead Relay On The graphical user interfaces.
However,Learning To Use The Terminal Is Recommended Since It Plays An Important Role In Ethical Hacking.
11.What's GIT?
The Git version control framework is distributed to monitor transmutations in files of any kind. It was designed to build the Linux kernel by Linus Torvalds in 2005. Microsoft, Google Even Facebook Use GIT.
In contrast to the prodigious majority of client server systems, every computer's Git directory contains a plenary, historical repository. Git is licensed under GNU GPL version 2 and is open-source software.
You can Learn More About GIT For Free From The Git book.
