KALI LINUX OS

An open source penetration testing platform.

WHAT IS KALI LINUX ?

• Kali Linux is a Debian-based Linux distribution aimed at

advanced Penetration Testing and Security Auditing.

• It contains several hundred tools which are geared

towards various information security tasks, such as

Penetration Testing, Security research, Computer

Forensics and Reverse Engineering.

• Kali Linux is developed, funded and maintained

by Offensive Security a leading information security

training company.

WHAT IS PENETRATION

TESTING?

• It is also termed as pen-testing, and is an authorized

simulated attack on a computer system, performed to

evaluate the security of the system.

• This is done to identify both the weaknesses /

vulnerabilities, including the potential of unauthorized parties

to access to the systems features and data as well as

strengths, enabling a full risk assessment to be completed.

WHAT DOES KALI

HAVE??

• More than 600 penetration testing tools

• It is free and always will be

• Open source Git tree (A Git is a distributed version control

systems, it can be used as a server out of the box. Git refers

to dictionaries as “ trees”.)

• Kali adheres to the File System Hierarchy Standard,

allowing Linux users to easily locate binaries, support files,

libraries, etc.

• Wide-ranging wireless device support.

• Custom kernel, patched for injection.

• Developed in a secure environment.

• GPG signed packages and repositories which means every

package in Kali Linux is signed by each individual developer

who built and committed it, and the repositories subsequently

sign the packages as well.

• Multi-language support.

• Completely customizable.

• ARMEL and ARMHF support which means it is compatible

with single board systems like Raspberry Pi, Beagle Bone

Black.

• A minimal and trusted set of repositories, the set of

upstream software sources which Kali uses is kept to an

absolute minimum. Many new Kali users are tempted to

add additional repositories to their sources.list, but doing

so runs a very serious risk of breaking your Kali Linux

installation.

SHOULD IT BE USED BY

ALL??

• Kali was specifically designed for penetrating professionally

through a system , hence ehy it is NOT recommended as a

distributed system like linux and may not be as easy to use as

linux which is a distributed sysytem.

• NOTE: Kali is an open source but not a wide open

source , it has a small and trusted team.

• In addition, misuse of security and penetration testing

tools within a network, particularly without specific

authorization, may cause irreparable damage and result

in significant consequences, personal and/or legal. “Not

understanding what you were doing” is not going to work

as an excuse.

SYSTEM

REQUIREMENTS

• Kali has some minimum suggested specifications for

hardware. Depending upon the intended use, more may be

desired. This guide will be assuming that the reader will want

to install Kali as the only operating system on the computer.

• At least 10GB of disk space; strongly encouraged to have

• At least 512MB of RAM; more is encouraged especially for

graphical environments

• USB or CD/DVD boot support

• Kali Linux ISO available from https://www.kali.org/downloads/

FLEXIBILITY OF KALI

LINUX

• Kali Linux can run natively when installed on a computer’s

hard disk or,

• It can be booted from a live CD or a live USB or, it can be run

on a virtual machine.

• It can also be installed within a chroot environment on an

android device.

KALI LINUX LIVE USB

INSTALL PROCEDURE

• The specifics of this procedure will vary depending on

whether you’re doing it on a Windows, Linux, or OS X system.

• This guide will be assuming that a USB drive is available to

use as the installation media. Take note that the USB drive

should be as close to 4/8GB as possible and ALL DATA WILL

BE REMOVED.

•

PROCEDURE TO

CREATE A

BOOTABLE PEN

DRIVE AND INSTALL

KALI.

• After rebooting machine, you will be prompted with Kali Linux boot

menu, from the list choose Kali GNU/Linux without recovery mode to

boot normally to system.

• After system booting, you will get the login screen for KALI Linux 1.1.0,

use the default username as ‘root’ and password which you’ve set

during the installation time at #step 10.

We have successfully installed Kali Linux

1.1.0 and your system is ready to customize

as per your requirements.

Updating Kali Linux from Older Version to

1.1.0 :

To upgrade Kali from older versions to

newer 1.1.0, you can use the simple apt-

get commands. We don’t have to download

the ISO files and have a fresh new

installation, just issue the following

commands to upgrade the running system

into newer version.

PENETRATION-TESTING

PROGRAMS

• nmap – a port scanner.

• Wireshark – a packet analyzer.

• John The Ripper – a password cracker.

• Aircrack-ng - a software suite for penetration testing wireless

LAN’s.

• iKat - a hacking tool

• Hydra – Brute force password cracking tool.

• Maltego - Information on visualization and relationship analysis

tool.

• Metasloit- framework for developing and executing exploits.

• Owasp- Zap - Integrated pen-testing tool for web application.

• Sqlmap – finds SQL injection flaws for taking over of database

servers.

Kali tool list – a cheat sheet

Ubuntu

• Ubuntu is a general

desktop and server

distribution.

• Designed to satisfy

general Desktop and

Server requirements and

also targeted in some

Smart TV’s.

• Developed by Canonical

Ltd. and released back in

2004.

Kali Linux

• Kali Linux is a specialized

distribution.

• Primarily designed for

purposes like penetration

testing and digital forensics.

• Developed by Offensive

Security Ltd. and released

on 13 th March 2013.

• The latest version released

is Kali 2.0

Windows

Kali

• Open source

• Free software

• Live CD distribution

• Secure

• No virus, Malware

• Low hardware cost

• Customizable and features.

• Closed source

• Cost s around Rs. 7000 for

only the non-pro OS

• No CD and Usb distribution

through common Cd’s.

• Insecure to an extent

• Can be effected by a virus and

malware.

• High hardware cost.

• Not customizable.

DEVELOPER’S POINT OF VIEW

Mati Aharoni is the founder and core developer of kali Linux

project, as well the CEO of Offensive Security.

According to him-

“It is critical to take the view of the attacker to see if

your defenses are working.”

This is the main idea behind the development of Kali Linux

• ADVANTAGES:

• The main advantage of kali is that it is helps us test

penetration legally , giving us a benefit to find out loop holes

which serve as open entry points to our system.

• Basically helping us to be safe than sorry .

• It is highly secure .

• DISADVANTAGES:

• The disadvantage of this system is that it does not function

like a normal OS and cannot be used as one.

• It gives a complete access an knowledge of penetration , that

if not used wisely could have a near disastrous effect.
