Exam Preparation Tips

Proven strategies for passing OT security certification exams.

🎯 Focus on Scenario-Based Questions
GICSP and GRID exams are heavily scenario-based. Practice applying concepts to real-world OT situations, not just memorizing definitions. Use the OT Academy exam engine's scenario mode.
📋 Master the IEC 62443 Framework
IEC 62443 appears in virtually every OT security exam. Know the 7 Foundational Requirements, 4 Security Levels, and Zone/Conduit model cold. Use the IEC 62443 deep-dive module.
⚡ Know Your Protocols
Modbus, DNP3, EtherNet/IP, and OPC-UA appear on every exam. Know port numbers, function codes, security weaknesses, and real-world attack examples (Stuxnet, Industroyer, PIPEDREAM).
🔬 Practice with Labs
Hands-on experience dramatically improves exam performance. Complete at least 5 virtual labs before sitting for GICSP or GRID. The OT SOC triage lab is especially valuable for GRID.
📅 Schedule Your Exam Early
Book your exam date 6-8 weeks out to create accountability. GICSP and GRID exams are proctored and require advance scheduling. Use the deadline as motivation to complete your study plan.
