How to be a Pen tester? This has to be one of the most frequently asked questions on any security forum and I will try my best to answer this question. For anyone looking to break into Penetration testing the best place to start is reading about it and networking. I would also advise that you are 100% sure this is what you really want to do because to be a good Penetration tester it takes time, effort and a lot of reading and frustration.
Once you are happy this is what you really want to do, take the next steps. One of the most important steps you can take is to download a Linux Distro like Kali which comes built with every security tool know to man on it. This can be then used in a lab setup to practice you skills and learn more about tools in a controlled environment.
Pentesting it not just about using tools clicking and pointing its really critical you understand whats going on and how the tools are working so it would be great if you have a programming background most tools are written in python as its easy to learn. If you don’t have a programming background then learn something either python or perl would be a great starting points.
Use the internet, Google is your friend. There are so many videos, books, white papers and more on the internet, find them, read them, watch them and enjoy them as well as learning from them.
There is also wide range of courses online for Penetration testers. If you can afford it then do a course as its gives you something to speak about during interview and looks great on a CV.
This is the most important of them all whilst trying to get involved with security. You need to get your name out there. You can do this by attending security conferences, writing security tools and giving talks. When I was looking I got many interviews by just speaking to people at conferences and events telling them I want a job.
When you work in security or as you go along with your studies you are going to learn lots of new stuff and lots complex stuff. A really good thing to do is install a wiki on you machine and log all the new stuff you learn in it I tend to use moin wiki which has notes on everything.
