How to Prepare for the GICSP Exam
Preparation Steps
Start by reviewing the GIAC GICSP blueprint, which outlines key areas like ICS architecture, attack surfaces, defense strategies, incident response, and governance [8]. A great resource to consider is the SANS ICS410: ICS/SCADA Security Essentials course. This course is tailored to match these objectives and dives into topics like the Purdue Reference Architecture (Levels 0–3) and hands-on protocol analysis [17].
To make the most of your open-book exam, create a well-organized physical index. Alphabetize definitions and explanations from your study materials for quick reference [14]. Since digital resources aren’t allowed, this index can be a lifesaver. Tools such as Voltaire or Lesley Carhart’s GIAC Indexing Guide offer helpful tips for structuring it [17]. If you’re working full-time, aim to dedicate 2–3 hours on weekday evenings and full days on weekends, allowing about 3–4 weeks for preparation [17].
Hands-on skills are also critical. Practice using tools like Wireshark for analyzing industrial protocols, and get comfortable with PowerShell, Linux command-line operations, and basic PLC programming (like ladder logic) [18]. These skills are especially important for the CyberLive sections of the exam, where you’ll solve practical security challenges using real code and virtual machines [8]. This blend of theoretical study and hands-on practice will prepare you for both the exam and real-world scenarios.
Study Resources and Tools
Alongside the SANS ICS410 course, GIAC’s official practice tests are a must. They simulate the 3-hour exam environment and help you identify any weak areas [17]. As Keirsten Brager, a Lead Security Engineer, points out:
"The practice tests in the course are meant to reinforce the knowledge gained in the course, not pass the GIAC exam. GIAC has its own practice exams that simulate the real environment."
These practice exams cost around $399 and closely mirror the actual test format [14].
For additional study, consider the book Practical Industrial Cybersecurity: ICS, Industry 4.0, and IIoT by Wiley, which is specifically designed to support GICSP exam preparation [19]. Spending time in virtual lab environments like CyberLive is also highly recommended. These labs let you work with real programs and code, sharpening your practical skills [8]. During the exam, aim to answer multiple-choice questions in about one minute each, leaving enough time for the hands-on scenarios [18].
Once you’ve gathered your resources and mapped out your study plan, take time to familiarize yourself with the exam format and related costs.
Exam Format, Cost, and Requirements
You can take the exam remotely through ProctorU or in person at PearsonVUE testing centers [8]. It’s open-book, meaning you can bring printed materials and your index, but digital resources are strictly prohibited [14]. The exam structure emphasizes hands-on skills, reflecting the practical focus of the certification.
For remote testing, you’ll need two forms of government-issued ID, such as a driver’s license and passport, and these must match the details on your exam record [17].
The exam costs $1,899 for the initial attempt, with retakes priced at about $899 after a required 30-day waiting period [14]. Other expenses include a $175 reseating fee for missed exams and a certification renewal fee of approximately $499 every four years [14]. Keep in mind, you have 120 days from the activation date to complete your certification attempt [8], so plan your schedule wisely.
