Delighted to announce that I am now certified GIAC
Penetration Tester (GPEN)!
Here is my journey towards getting certified:
As you might know, each GIAC course comes with 2 online certification
attempts. These can be done at any time prior the exam, which is a perfect way
to determine how prepare you are. I decided to give myself 2 weeks to sit the
exam (I like to work intensely in a short period of time).
Prior to the first online attempt, I prepared a “high-level”
cheat sheet with roughly the subjects addressed in each books. Feeling ready, I
sat the online exam to gauge my current skills and miserably failed with 64%
(pass mark 74%).
This made me realised that the cheat sheet had to be a lot
more detailed. I decided to tweak it by referencing the name of every single
tool mentioned in the course books. The cheat sheet was now 3 pages long.
My second online attempt resulted in another fail, with 1%
below the pass mark. Timing is crucial, I realised that I went way too fast (2hours
instead of the allocated 3hours) which resulted in half a dozen mistakes.
Therefore, I completed my cheat sheet with a time table to know roughly how
long I could take for every 15 questions.
I also purchased the “Red Team Field Manual”, which I highly
recommend. The book is constituted of 1 line commands for a broad range of
tools used during the GPEN (and many more).
On the day of the exam, I brought to the test center all 5
GPEN books, my hand-made cheat sheet and the RTFM. After 2hours and 57minutes,
I passed the certification with an 86% success rate. I have to say that the
cheat-sheet was essential; to quickly search for commands/subjects and avoid
making mistakes. In addition, I took my time to answer and didn’t rush through it,
which resulted in a much higher score than online attempts.
In conclusion, the exam itself was very similar to the
online attempts (but different questions). The cheat sheet is crucial, so
please feel free to tweak yours using the above idea/tips and I wish you all
the best for your exam!
