IEC 62443-4-2 Compliance: Securing Industrial Components by Design
What is IEC 62443-4-2?
IEC 62443-4-2 is part of the IEC 62443 series, focusing specifically on technical security requirements for IACS components. It complements the system-level standard (IEC 62443-3-3) by defining mandatory capabilities for products such as:
01.
Embedded devices (e.g., sensors, controllers)
02.
Network components (e.g., routers, switches)
03.
Host devices (e.g., servers, workstations)
04.
Software applications
