GCIA Certification Bulletin

(Part 2 of Candidate Handbook)

The GIAC Intrusion Detection In-Depth (GCIA) was created to provide assurance that a certified individual holds the appropriate level of knowledge and skill necessary for anyone relied upon by an organization to perform intrusion detection using network and host-based techniques.

All GIAC certifications expire after a period of 4 years. In order to recertify, candidates must take the current version of the certification exam.

The practice tests are taken on-line and are designed to simulate the format of the actual GIAC exams with the same number of tests, multiple-choice questions and time-limits. The practice test questions are written by the same authors who write the questions for the actual GIAC exams and are representative of the types of questions you can expect to see. However, it is important to keep in mind that no exam questions are identical in content to practice exam questions. During the practice tests, each time you choose a wrong answer you will receive the correct answer along with an explanation that will help to reinforce the subject matter presented in the question. The practice tests also keep track of the number of questions you have answered correctly, incorrectly and how many questions you have remaining. You will only have one attempt at each practice test, but if you would like additional attempts they are available for purchase. If you do purchase a new practice test set, the on-line system will re-quiz you on those questions you had difficulty with, in addition to new questions.

Where to Get Help

Training is available from a variety of resources including on line, course attendance at a live conference, and self study.

Practical experience is another way to ensure that you have mastered the skills necessary for certification. Many professionals have the experience to meet the certification objectives identified.

Finally, college level courses or study through another program may meet the needs for mastery.
