In the final application, an appropriate security environment is necessary to protect both the operational environment and the safety-related systems.

This document does not cover security aspects, nor does it provide any requirements for security.

A threat and risk analysis (TRA) according to the IEC 62443 series shall be carried out on a final application system level.

During compliance tests for this document, security aspects are not part of the scope, as it is assumed that the underlying base mechanisms (i.e. Methods) already provide adequate security.
