I did not tell anyone that i was preparing for the GIAC GCIA certification exam. I prepared secretly online to surprise everyone with the results. I prepared day and night whenever i got time because due to my office work, it was a little time consuming and also i did not have much spare time left. However, the practice tests were designed in a manner that the GIAC Certified Intrusion Analyst syllabus could be cleared easily in a matter of two months only. This is how i went about and felt great when the result came and everybody was surprised and proud of me.
