About this event

A live 30-minute expert session on Security Acceptance Testing at FAT and SAT — Verifying the Built System (IEC 62443 — Industrial Cybersecurity). What We'll Cover: What cyber FAT/SAT is and where it sits between system integration and operational handover in the IACS lifecycle The method step by step: derive test cases from the SR compliance matrix, verify configurations, run vulnerability scans in the factory, retest deltas at site How test cases map to 62443-3-3 requirements and the FAT/SAT security test reports and punch lists produced Common mistakes: testing only functionality, scanning at site instead of factory, accepting open punch items without risk sign-off The evidence an assessor wants at handover: requirement-linked test results, hardening verification and credential handover records Related topics: cyber fat · security acceptance testing · sat testing · handover security · test case derivation · factory acceptance · vulnerability scan staging · punch list · requirement verification · commissioning security · credential handover · integration testing Critical Systems Analysis provides embedded functional safety consulting for IEC 62443 — Industrial Cybersecurity.

About Functional Safety Foundations

This online session delivers expert-led instruction on the regulatory landscape and implementation approach for Functional Safety Foundations.

The cross-sector fundamentals underlying every functional safety standard: risk as severity × likelihood, the safety function concept, integrity levels, the safety lifecycle, and the split between random and systematic failures.

What it regulates

Shared vocabulary and reasoning: hazard → risk → risk reduction allocation → safety requirement → verified implementation → maintained integrity in operation.

Who must comply

Everyone entering the field — the conceptual base of the entire catalog.

Key requirements of Functional Safety Foundations

  • Hazard and risk fundamentals
  • Safety function anatomy: sensor-logic-actuator with defined safe state
  • Integrity ladders (SIL/PL/ASIL/DAL) as risk-reduction currencies
  • Random vs systematic failure treatment
  • Lifecycle and management of functional safety incl. competence

Key concepts: Functional Safety Foundations

Functional safety management
Planning, competence, documentation and assessment wrapped around technical work.
Random vs systematic
Hardware wear-out/chance failures quantified statistically versus design/process errors controlled by rigor.
Risk reduction allocation
Distributing required risk reduction among mechanical design, safeguards, control functions and procedures.
Safe state
The defined condition a function drives the equipment to on demand or fault.

Frequently asked questions: Functional Safety Foundations

Why can't testing alone prove safety?

Rare-event targets (like 1e-7/h) are unverifiable by test duration, and systematic errors evade random testing — hence the standards' dual machinery of quantified hardware analysis plus process rigor and independent assessment.
