Thanks to my family for their unending support and prayer, you are truly a gift from God!
Thanks to my friends in the infosec & cybersecurity community for sharing your knowledge and
time with me. And thanks to my friends in our local book writers club (especially you Bill!),
without your input, companionship and advice, this would have never happened.

Basic Security Testing With Kali Linux

About the Author
Daniel W. Dieterle has worked in the IT field for over 20 years. During this time he
worked for a computer support company where he provided computer and network
support for hundreds of companies across Upstate New York and throughout Northern

He also worked in a Fortune 500 corporate data center, briefly worked at an Ivy League school’s computer support department and served as an executive at an electrical engineering company.

For about the last 5 years Daniel has been completely focused on security. He created and authors the “CyberArms Computer Security Blog”, and his articles have been published in international security magazines, and referenced by both technical entities and the media.
Daniel has assisted with numerous security training classes and technical training books mainly based on Backtrack and Kali Linux.

What is Kali?
Kali is the latest and greatest version of the ever popular Backtrack Linux penetration testing
distribution. The creators of the Backtrack series kept Kali in a format very similar to Backtrack, so anyone familiar with the older Backtrack platform will feel right at home.

Kali has been re-vamped from the ground up to be the best and most feature rich Ethical Hacking/
Pentesting distribution available. Kali also runs on more hardware devices greatly increasing your
options for computer security penetration testing or “pentesting” systems.

If you are coming to Kali from a Backtrack background, after a short familiarization period you
should find that everything is very similar and your comfort level should grow very quickly.

If you are new to Kali, once you get used to it, you will find an easy to use security testing platform that includes hundreds of useful and powerful tools to test and help secure your network systems.

Why Use Kali?
Kali includes over 300 security testing tools. A lot of the redundant tools from Backtrack have been removed and the tool interface streamlined. You can now get to the most used tools quickly as they appear in a top ten security tool menu. You can also find these same tools and a plethora of others all neatly categorized in the menu system.

Kali allows you to use similar tools and techniques that a hacker would use to test the security of your network so you can find and correct these issues before a real hacker finds them.

I would think the biggest drive to use Kali over commercial security solutions is the price. Security testing tools can be extremely costly, Kali is free! Secondly, Kali includes open source versions of numerous commercial security products, so you could conceivably replace costly programs by simply using Kali.

All though Kali does includes several free versions of popular software programs that can be
upgraded to the full featured paid versions and used directly through Kali.

There really are no major tool usage differences between Backtrack and Kali. Kali is basically
Backtrack version 6, or the latest version of Backtrack. But it has been completely retooled from the ground up, making software updates and additions much easier.
In Backtrack updating some programs seemed to break others, in Kali, you update everything using the Kali update command which keeps system integrity much better.

Simply update Kali and it will pull down the latest versions of the included tools for you. Just a note of caution, updating tools individually could break Kali, so running the Kali update is always the best way to get the latest packages for the OS.

I must admit though, some tools that I liked in the original Backtrack are missing in Kali. It is not too big of a deal as another tool in Kali most likely does the same or similar thing. And then again you can install other programs you like if needed.

In addition to stand alone and virtual machine instances of Kali, I also use Kali on a Raspberry Pi - a mini credit card sized ARM based computer. With Kali, you can do almost everything on a Pi that you could do on a full sized system. In my book I will cover using the PI as a security testing platform including testing Wireless networks.

Testing networks with a computer you could fit in your pocket, how cool is that?
Though Kali can’t possibly contain all the possible security tools that every individual would prefer, it contains enough that Kali could be used from beginning to end. Don’t forget that Kali is not just a security tool, but a full-fledged Linux Operating System. So if your favorite tool runs under Linux, but is not included, most likely you can install and run it in Kali.

Ethical Hacking Issues
Using Ethical Hacking a security tester basically acts like a hacker. He uses tools and techniques that a hacker would most likely use to test a target network’s security. The difference is, the penetration tester is hired by the company to test its security and when done reveals to the leadership team how they got in and what they can do to plug the holes.

The biggest issue I see in using these techniques is ethics and law. Some security testing techniques that you can perform with Kali and its included tools are actually illegal to do in some areas. So it is important that users check their local, State and Federal laws before using Kali.
Also, you may have some users that try to use Kali, a very powerful set of tools, on a network that they do not have permission to do so. Or they will try to use a technique they learned but may have not mastered on a production network.
All of these are potential legal and ethical issues.

Scope of this Book
This book focuses on those with beginning to intermediate experience with Backtrack/ Kali. I think it would also be a good tool for network administrators and non-security IT professionals that are looking to get into the field.

We will cover everything from a basic overview of Kali to using the included tools to test security on Windows and Linux based systems. We will cover Social Engineering, Wi-Fi security, using Kali on a Raspberry Pi, exploiting passwords, basic computer security testing from reconnaissance to finding & using exploits, and finally securing your systems.

Why did I write this book?
I have written technical articles on Backtrack for several years now, and have helped out with
multiple Backtrack/ Kali books and training series. I get a lot of questions on how to use Kali/
Backtrack, so I decided that it was time to write my own beginners guide book.

My other reason for writing this book is to help get young people interested in the field of computer security. The US is currently facing a crisis when it comes to young professionals choosing technical careers and the cyber security field is no different.

The US government is in need of thousands1 of cyber warriors and some industry experts have even suggested that the US consider hiring security experts2 from other countries to fill in the gap. Think about that for a minute.
The numbers game is against us also. The US is the number two user of the internet, with 81% of our population connected. Now consider the fact that China is in the number one spot3 with almost double the amount of users. And their connected rate is only at about 41%!

Though many think that the US is ranked number one in cyber offense capabilities, our defense is not ranked that well. With foreign countries making marked advances in cyber security the US needs to get as many brilliant young people into the field as possible, and they need to do it sooner rather than later.
