IEC 62443-4-2 Standard Overview

IEC 62443-4-2 is a core standard within the IEC 62443 series, specifically developed to define security technical requirements for Industrial Automation and Control System components (IACS Components). The standard requires that cybersecurity protection mechanisms be incorporated into products from the design, development, and implementation stages, and that their security capabilities be evaluated through standardized testing to determine compliance with the standard’s requirements.

Seven Foundational Requirements (FRs):

  1. Identification and Authentication Control (IAC)
  2. Use Control (UC)
  3. System Integrity (SI)
  4. Data Confidentiality (DC)
  5. Restricted Data Flow (RDF)
  6. Timely Response to Events (TRE)
  7. Resource Availability (RA)


Applicable Scope

This testing service is applicable to the following product types and industry scenarios:

  • Industrial control equipment
  • Industrial embedded devices and control modules
  • Industrial communication and network devices
  • Industrial control–related software
  • Internet of Things (IoT) devices applied in industries such as manufacturing, energy, power, water utilities, transportation, and smart factories

This service is particularly suitable for enterprises with the following needs:

  • Products intended for export to European, American, or Asia-Pacific markets
  • Requirements to comply with international OT / IoT cybersecurity procurement standards
  • Regulatory or customer mandates to provide IEC 62443 testing reports
  • The intention to establish cybersecurity-driven competitive advantages during the product design phase


International Compliance and Market Trends

IEC 62443-4-2 has been widely adopted across Europe, the Americas, and the Asia-Pacific region, and has become a key reference for OT and IoT device procurement as well as supply chain security evaluations.

In addition, the European Union’s recently adopted Cyber Resilience Act (CRA) incorporates IEC 62443 as a reference framework, recognizing it as one of the core standards for defining cybersecurity requirements for critical infrastructure and industrial control equipment.

Looking ahead, products that do not comply with IEC 62443-related testing requirements may face regulatory barriers and commercial risks when entering the European Union market. As a result, obtaining relevant certification has become a critical strategic priority for enterprises seeking to expand into international markets.



Service Value

Through iForensics’ IEC 62443-4-2 testing services, enterprises can expect to achieve the following objectives:

  • Verify product compliance with international industrial control cybersecurity standards through standardized processes
  • Reduce operational risks resulting from cyberattacks targeting OT and IoT devices
  • Enhance product trust and credibility across international markets, supply chains, and customers
  • Proactively address compliance challenges arising from emerging regulations such as the Cyber Resilience Act (CRA)
