Network security

2.2.4.1

Basics

Introduction
The topic of data security and access protection (Security) has become increasingly
important in the industrial environment. The increased networking of entire industrial
systems, vertical integration and networking of levels within a company and new techniques
such as remote maintenance all result in higher requirements for protecting the industrial
plant.
Data security solutions for office environments cannot simply be transferred one-to-one to
industrial applications to protect against manipulation in sensitive systems and production
networks.
Requirements
Additional security requirements arise from the specific communication requirements in the
industrial environment (real-time communication, for example):
● Protection against interaction between automated cells
● Protection of network segments
● Protection against faulty and unauthorized access
● Scalability of network security
● Must not influence the network structure
