About this event

A live 30-minute expert session on 62443-4-2 Component Requirements — CRs for Embedded Devices, Hosts and Network Gear (IEC 62443 — Industrial Cybersecurity). What We'll Cover: What 62443-4-2 is, the four component types (embedded device, host, network device, software application), and where it sits after 4-1 in product certification The method step by step: map product functions to CRs per FR, determine achievable SL-C per requirement, document deviations and compensating guidance How CRs map to the 3-3 SRs they support and the protection profile and SL-C datasheet a vendor produces Common mistakes: claiming SL-C without covering the REs, hiding non-conformances in user documentation, ignoring EDR-specific requirements Evidence certifiers look for: CR-by-CR test reports, secure-by-default configuration proof, and the linkage back to a certified 4-1 process Related topics: iec 62443-4-2 · component requirements · sl-c · embedded device requirements · edr ncr har · product certification · csa certification · device security capability · secure by default · component security · plc security requirements · vendor datasheet 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.
