Scope

during conformity assessment activities) to achieve repeatable and reproducible evaluation
results against IEC 62443-2-4 requirements. This document is intended for first-party, secondparty
or third-party conformity assessment activity, for example by product suppliers, service
providers, asset owners and conformity assessment bodies.

capabilities can be offered as a security program during integration and maintenance of an automation solution.

conformity assessment activity and third-party conformity assessment activity are defined in ISO/IEC 17000.
