If you're studying for the ISA IC32 exam, finding good practice material can be frustrating. Most of what's available is either behind a paywall or lacks proper explanations.
This quiz covers the five IC32 topic areas with twenty scenario-based questions. You pick your answer, see if you got it right, and read a short explanation of why. At the end, your score breaks down by topic so you know where to focus before exam day.
We built this using Blend-ed's AI Course Creator, which is how training companies on our platform create certification assessments. More on that after the quiz.
What does the IC32 exam cover?
The ISA/IEC 62443 Cybersecurity Fundamentals Specialist exam tests whether you can apply the ISA/IEC 62443 standards to secure industrial automation and control systems (IACS). This is not an IT security exam. Everything is framed around operational technology: chemical plants, power stations, water treatment, manufacturing.
The passing threshold is around 70-75%. ISA doesn't publish the exact number, but that's what candidates report.
Certificate 1 is the required starting point. You need it before you can sit Certificates 2, 3, or 4. Everyone pursuing the Cybersecurity Expert designation starts here.
The exam covers five areas:
Core concepts and terminology
The four parts of the ISA/IEC 62443 series. The seven Foundational Requirements. The three lifecycle phases: Assess, Implement and Maintain, Operate. You need to understand how these connect, not just what they're called.
Zones and conduits
Grouping assets into security zones. Defining conduits between them. Assigning target security levels based on risk. The exam gives you scenarios and asks how you'd segment a system.
Defence in depth
Multiple independent layers of security: physical, network, host, application, people, and processes. The key idea is that no single layer protects the system alone.
CSMS
The Cybersecurity Management System defined in ISA/IEC 62443-2-1. Policies, risk assessment, personnel security, incident response, continuous improvement. The exam tests whether you know when a CSMS review should happen and what counts as an organisational measure vs a technical control.
IT vs OT differences
IACS puts availability first, not confidentiality. You can't reboot a reactor. Patches need testing before deployment. Equipment runs for 15-25 years on operating systems that no longer get updates.
Take the quiz
20 scenario-based questions. 5 topic areas. Instant feedback after each answer. Score breakdown at the end.
What your score means
Above 80% in a topic. You're solid. Review the explanations for anything you missed and move on.
60-79%. You know the basics but the details are fuzzy. Go back to the relevant ISA/IEC 62443-1-1 sections for that topic. Focus on the concepts that tripped you up, not the whole document.
Below 60%. Spend real time here before the exam. The IC32 course comes in four formats: classroom, virtual, instructor-guided online, and self-paced modular. This might be the area that convinces you to enrol.
Come back in a few days and retake it. The questions stay the same. Your understanding should change.
How we built this quiz
We used Blend-ed's AI Course Creator. IEC 62443 reference material went in. The AI generated assessment questions mapped to learning objectives. We reviewed every question for technical accuracy and published. About 15 minutes from source material to working quiz.
For context, Blend-ed is an AI-first LMS built for training companies that deliver certification programmes to external clients. The AI Course Creator is one part of a larger platform that also handles cohort management, certificate issuance, exam workflows, and expiry tracking.
Risknowlogy, a TUV SUD approved IEC 61508 training provider, runs their full operation on it. If you deliver IEC 62443 programmes and you're curious what a purpose-built platform looks like for this kind of training, the quiz you just took is a small preview.
What to do next
Bookmark this page. Retake the quiz until you hit 80% across all five topics.
The two documents that matter most for IC32 are ISA/IEC 62443-1-1 (concepts and models) and ISA/IEC 62443-2-1 (CSMS requirements). Everything in the exam connects back to them.
If you deliver IEC 62443 certification training and want to see how Blend-ed handles this kind of workflow end to end, book a demo.
Frequently Asked Questions
How hard is the ISA IEC 62443 IC32 exam?
Challenging but doable with preparation. It tests practical application, not memorisation. You get scenarios about IACS environments and apply concepts like zones and conduits and defence in depth. The passing threshold is around 70-75%.
What topics are on the IEC 62443 Cybersecurity Fundamentals exam?
Five areas: ISA/IEC 62443 standards structure, zones and conduits, defence in depth, CSMS from ISA/IEC 62443-2-1, and IT vs OT security differences. All framed around industrial automation, not corporate IT.
What's the passing score for the IC32 exam?
ISA doesn't publish the official number. Based on candidate reports, you need roughly 70-75% correct on the multiple-choice exam. Registration includes the exam fee.
Do ISA IEC 62443 certificates expire?
No. ISA certificates don't require renewal. Once earned, they stay valid. But note: other bodies like Kiwa/IBEX issue IEC 62443 certificates with 2-year validity. Expiry depends on which body administered your exam.
What's the best way to prepare for the IEC 62443 exam?
Take the IC32 course. Review ISA/IEC 62443-1-1 and 2-1 in detail. Practice with quizzes to find gaps. Focus on understanding how concepts connect across the IACS cybersecurity lifecycle. The exam rewards practical understanding, not memorised definitions.
