IEC 62443-4-2 — Technical security requirements for IACS components
Translates the Foundational Requirements into concrete technical requirements at component level (embedded devices, network components, host and software applications).
For which role
Product suppliers; relevant for asset owners and integrators when selecting products.
Key topics
- •Component types: embedded, network, host, application
- •Technical requirements per Foundational Requirement and Security Level
- •Certifiable component requirements
Expected results
- •Components with demonstrable, certified security functionality
- •Unambiguous basis for procurement requirements at asset owners
Relationship to other parts of the standard
Component requirements that together form a system that can satisfy -3-3.
Practical example from the energy sector
A grid operator includes IEC 62443-4-2 certification as a procurement requirement for new protection relays in substation projects.
