Kali linux Introduction

Kali linux Introduction

Kali Linux is the world’s most powerful and popular penetration testing platform, used by security
professionals in a wide range of specializations, including penetration testing, forensics, reverse
engineering, and vulnerability assessment. It is the culmination of years of refinement and the
result of a continuous evolution of the platform, from WHoppiX to WHAX, to BackTrack, and now
to a complete penetration testing framework leveraging many features of Debian GNU/Linux and
the vibrant open source community worldwide.
Kali Linux has not been built to be a simple collection of tools, but rather a flexible framework
that professional penetration testers, security enthusiasts, students, and amateurs can customize
to fit their specific needs.

Why Best Kali linux

Kali Linux is not merely a collection of various information security tools that are installed on a
standard Debian base and preconfigured to get you up and running right away. To get the most
out of Kali, it is important to have a thorough understanding of its powerful Debian GNU/Linux
underpinnings (which support all those great tools) and learning how you can put them to use in
your environment.

I would like to thank Mati Aharoni: in 2012, he got in touch with me because I was one out of
dozens of Debian consultants and he wanted to build a successor to BackTrack that would be based
on Debian. That is how I started to work on Kali Linux, and ever since I have enjoyed my journey
in the Kali world.
Over the years, Kali Linux got closer to Debian GNU/Linux, notably with the switch to Kali Rolling,
based on Debian Testing. Now most of my work, be it on Kali or on Debian, provides benefits to the
entire Debian ecosystem. And this is exactly what keeps me so motivated to continue, day after
day, month after month, year after year.
Working on this book is also a great opportunity that Mati offered me. It is not the same kind
of work but it is equally rewarding to be able to help people and share with them my expertise
of the Debian/Kali operating system. Building on my experience with the Debian Administrator’s
Handbook, I hope that my explanations will help you to get started in the fast-moving world of
computer security.
I would also like to thank all the Offensive Security persons who were involved in the book: Jim
O’Gorman (co-author of some chapters), Devon Kearns (reviewer), Ron Henry (technical editor),
Joe Steinbach and Tony Cruse (project managers). And thank you to Johnny Long who joined to
write the preface but ended up reviewing the whole book.

Acknowledgments of Jim O’Gorman

I would like to thank everyone involved in this project for their contributions, of which mine were
only a small part. This book, much like Kali Linux itself was a collaborative project of many hands
making light work. Special thanks to Raphaël, Devon, Mati, Johnny, and Ron for taking on the
lion’s share of the effort. Without them, this book would not have come together.

Acknowledgments of Mati Aharoni

It has been a few years since Kali Linux was first released, and since day one, I have always dreamt
of publishing an official book which covers the Kali operating system as a whole. It is therefore
a great privilege for me to finally see such a book making it out to the public. I would like to
sincerely thank everyone involved in the creation of this project—including Jim, Devon, Johnny,

and Ron. A very special thanks goes to Raphaël for doing most of the heavy lifting in this book,
and bringing in his extensive expertise to our group.
