IriusRisk Threat Modeling for IEC/ANSI 62443 is a dedicated module within the IriusRisk platform designed to support compliance with the IEC/ANSI 62443 standard for Industrial Automation and Control Systems (IACS) security. The module enables engineers and security analysts to identify security threats applicable to the design of industrial control systems, including PLCs, controllers, sensors, and other OT assets. It is targeted at manufacturers of network and industrial control systems, operational technology industries, critical national infrastructure sectors (rail, transport, power, petrochemicals, water, manufacturing), and medical technology providers. Core capabilities include: - Automated threat modeling to define controls specific to a system's design - Security baseline establishment and target security level tracking - A library of 27 independently-configured components for threat remediation - Coverage of all 186 pages of IEC/ANSI 62443 Parts 3-3 (Network and System Security) and 4-2 (Security for Industrial Automation and Control Systems) - Automated generation of security requirements and mandatory controls per component - Risk visualization to support compliance assessment and gap identification IriusRisk is a technical member of the ISA Security Compliance Institute, and the module is aligned with the global standard created by the ISA Global Security Alliance.
