PROFINET Security Guideline
With its Security Guideline, PI is presenting a concept for the first time that takes into account the threats and special requirements of the automation world. This concept aims to protect automation components, irrespective of the communication protocols used or the network structure. Through the use of proven and open security mechanisms, the integration into existing security concepts is also possible.
This guideline is intended for users and operators of industrial networks, particularly those using Ethernet-based PROFINET. It points out the key aspects for the establishment of a security concept in this environment and provides appropriate recommendations.

PROFINET Security Class 1 Guideline
As more and more IT functions and security features are implemented on field devices in the course of Industry 4.0, the security of data and communication is becoming increasingly complex and important. Functions for protecting integrity and authenticity must be implemented in PROFINET communication.
In order to increase security in PROFINET networks, different security classes are therefore gradually being introduced. In total, there will be 3 classes, whereas this document will only describe the extensions just for the PROFINET security class 1.
This document is intended to give component manufacturers, system vendors and users of the PROFINET technology an overview about the planned methods, applications and processes of the PROFINET Security extension in Security Class 1.
