Complete killexams.com practice sets on asset inventory and IACS scope documentation.
Week 3: Threat Modeling & Vulnerability Analysis
Study the structure of an IACS threat analysis. Understand the difference between asset vulnerabilities (inherent in products or designs) and configuration vulnerabilities. Practice interpreting Process Hazard Analysis (PHA) outputs in the context of cybersecurity consequences. The exam tests your ability to link physical consequences to cybersecurity failure modes — this is an OT-specific skill not found in IT security certifications.
Week 4: Risk Assessment & ANSI/ISA-62443-3-2
This is the core of Certificate 2. Work through ANSI/ISA-62443-3-2-2020 carefully — this standard directly defines the risk assessment methodology the exam tests. Focus on: consequence severity levels, unmitigated likelihood assessment, Security Level Target (SL-T) determination, and the relationship between risk and security level requirements. Run killexams.com timed practice sets focused exclusively on risk evaluation questions.
Week 5: Zones, Conduits & Countermeasure Selection
The zones and conduits model is fundamental to ISA/IEC 62443 architecture. Practice drawing zone and conduit diagrams from system descriptions. Understand how security level targets drive countermeasure selection — and how to evaluate countermeasure cost, complexity, and effectiveness to make meaningful recommendations. Use the killexams VCE simulator for full-length timed assessments.
Week 6: CRS Development & Full Mock Exams
The Cybersecurity Requirements Specification (CRS) is the output document of the entire assessment process. Know its structure, what it must contain, and how it feeds into subsequent design work (Certificate 3 territory). Complete at least two full timed mock exams using killexams.com. Target a consistent score above 80% before your actual exam date.
⚡ Exam Tips from ISA/CRAS Certificate Holders
- Think OT, not IT: The exam consistently tests OT-specific scenarios — SCADA systems, PLCs, DCS environments. IT security generalizations often lead to wrong answers.
- Know the lifecycle phases precisely: ISA/IEC 62443-1-1 defines the IACS cybersecurity lifecycle. IC33 covers the Assess phase. Know where Assessment ends and Design (IC34) begins.
- Understand SL-T vs SL-C: Security Level Target (what you want) vs Security Level Capability (what the system can provide) is a frequently tested distinction.
- Master zone and conduit documentation: Exam questions often present a system diagram and ask you to identify correct zone boundaries, conduit types, and security level targets.
- Read answer explanations carefully: The killexams.com practice question rationale notes are as valuable as the questions themselves — they explain the ISA/IEC 62443 reasoning behind each answer.
- Brownfield vs Greenfield: The exam tests both existing (brownfield) and new (greenfield) assessment scenarios. Preparation should cover both contexts.
