GIAC Certified Intrusion Analyst (GCIA)
GIAC Certified Intrusion Analysts (GCIAs) have the knowledge, skills, and abilities to configure and monitor intrusion detection systems, and to read, interpret, and analyze network traffic and related log files.
Individuals responsible for network and host monitoring, traffic analysis, and intrusion detection
Preparing for the GCIA Exam: Candidates may choose to prepare for the GCIA exam by taking the SANS Training Course: SEC503: Intrusion Detection In-Depth
*No Specific training is required for any GIAC certification. If candidates need help in mastering the objectives for this certification, there are many sources of information available. Practical experience is one option; there are also numerous books on the market covering Computer Information Security. Another option is SANS training, or any relevant courses from other training providers.*
- 1 proctored exam
- 150 questions
- Time limit of 4 hours
- Minimum Passing Score of 67%
GIAC reserves the right to change the specifications for each certification without notice. Based on a scientific passing point study, the passing point for the GCIA exam has been determined to be 67% for all candidates receiving access to their certification attempts on or after August 2nd, 2012. To verify the format of your current certification attempt, please read the Certification Information found in your portal account at https://exams.giac.org/pages/attempts.
Certifications must be renewed every 4 years. Click here for details.
NOTE: GIAC exams are NOT given the day after the conference ends.
GIAC certification attempts purchased without SANS training will be activated in your SANS/GIAC account within 24 business hours of purchase. GIAC certification attempts purchased with SANS training will be activated in your SANS/GIAC account 7 days after the end of the conference. In both cases, you will receive an email notification when your certification attempt has been activated in your account. You will have 120 days from the date of activation to complete your certification attempt. GIAC exams must be proctored through Pearson VUE. Please click the following link for instructions on How to Schedule Your GIAC Proctored Exam. GIAC exams are delivered online through a standard web browser.
