White Paper OT-Security - Classification of IEC62443

PROFINET , Security


This white paper first provides an overview of the various parts of the IEC 62443 series of standards
and briefly describes their contents. This is followed by an assignment of the standard parts to the
players in the OT security process. In the area of Operational Technology (OT) these are the plant
operators, the system integrators and the product suppliers.
Building on these front-up considerations, a classification of PROFINET follows. The role of
PROFIBUS & PROFINET International (PI) and the manufacturers of PROFINET products in the
OT security process are described. The document also includes a description, how plant operators
are supported in the OT security process.
