FAQ

In IEC 62443/ISA 99 terms, an OT system is defined as a “control system,” that is, a hardware or software component intended to be integrated into a final industrial automation and control system. PLCs, HMIs, SCADA systems, and safety instrumented systems are examples of OT systems.

The legislative references in the IEC 62443 standard directed at OT device manufacturers are found in IEC 62443-4-1 and IEC 62443-4-2 regarding the design requirements in conformity with legislation for systems, sub-systems, or hardware or software components.

As defined in IEC 62443-4-1, the manufacturer is required to implement certain cyber security practices when developing the product:

  • Specification of Security Guidelines
  • Security by design
  • Secure Implementation
  • Security V&V Testing
  • Security Guidelines
