How can I help with IEC 62443?

Seeded with ISA/IEC 62443 concepts for industrial automation and control systems (IACS): the asset owner, service provider, integrator, and product supplier roles; security risk assessment with zones and conduits (62443-3-2); the seven foundational requirements and the security levels for systems (62443-3-3) and components (62443-4-2); asset owner security programs (62443-2-1); and secure product development (62443-4-1).

• Work through a risk assessment for your control system, split it into zones and conduits, and assign a target security level (SL-T) to each zone and conduit.
• Compare the capability security levels (SL-C) of your systems and components with those targets, and plan the countermeasures that close the gaps.
• Lay out an asset owner security program or, as a product supplier, map your development practices to the secure lifecycle in 62443-4-1.

It gives implementation guidance to speed up your work. It is not a certification or conformity assessment, and it does not replace the official ISA/IEC texts or a qualified assessor. Parts of the series are revised over time, so check which edition of each part applies to you.
