About this event

A live 30-minute expert session on Building a CSMS with 62443-2-1 — The Asset Owner's Security Program (IEC 62443 — Industrial Cybersecurity). What We'll Cover: What a CSMS is, how 62443-2-1 structures it, and where it sits as the asset owner's counterpart to the vendor-facing parts The build step by step: risk analysis, policy and organization, selected countermeasures, implementation, monitoring and improvement How CSMS elements map to 62443-2-1 SPEs and the policy set, roles matrix and audit program it produces Common mistakes: copying the IT ISMS wholesale, no OT-specific incident procedures, CSMS ownership left with corporate IT The evidence an auditor samples: management commitment records, OT risk register, training records and internal audit findings Related topics: csms · iec 62443-2-1 · asset owner · security program · ot governance · security policies · iacs management system · isms vs csms · security organization · continuous improvement · internal audit · security program elements 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.
