Showing Off Your Newly Gained Knowledge

12.2. Showing Off Your Newly Gained Knowledge
Are you proud of your new Kali Linux skills? Would you like to ensure that you remember the
really important things? If you answer yes to one of those questions, then you should consider
applying for the Kali Linux Certified Professional program.
It is a comprehensive certification that will ensure that you know how to deploy and use Kali Linux
in many realistic use cases. It is a nice addition to your resume and it also proves that you are ready
to go further.

Kali Linux Revealed
12.3. Going Further
This book taught you a lot of things that any Kali Linux user should know, but we made some hard
choices to keep it short, and there are many topics that were not covered.
12.3.1. Towards System Administration
If you want to learn more about system administration, then we can only recommend that you
check out the Debian Administrator’s Handbook:
è
https://debian-handbook.info/get/
You will find there, many supplementary chapters covering common Unix services that we have
entirely skipped in this book. And even for chapters that have been reused in the Kali book, you
will find plenty of supplementary tips, notably on the packaging system (which is also covered
more extensively at its lowest level).
The Debian book obviously presents more deeply the Debian community and the way it is orga-
nized. While this knowledge is not vital, it is really useful when you have to interact with Debian
contributors, for example through bug reports.
12.3.2. Towards Penetration Testing
You probably noticed by now that this book did not teach you penetration testing. But the things
you learned are still important. You are now ready to fully exploit the power of Kali Linux, the
best penetration testing framework. And you have the basic Linux skills required to participate
in Offensive Security’s training.
If you feel that you are not yet ready for a paid course, you can start by following the
Metasploit
Unleashed
3
free online training. Metasploit is a very popular penetration testing tool and you
have to know it if you are serious about your plans to learn penetration testing.
The next logical step would then be to follow the
Penetration Testing with Kali Linux
4
online
course leading the path to the famous “Offensive Security Certified Professional” certification.
This online course can be followed at your own pace but the certification is actually a difficult,
24h long, real-word, hands-on penetration test which takes place in an isolated VPN network.
Are you up to the challenge?
