BECKHOFF IPC-Security - Manual (Page 26)

5. Remote Access
5.1. Overview
This chapter is based on the scenario that a cyber criminal tries to attack the industrial controller from a
remote location, e.g. via the local network. Network connectivity provides a cyber criminal with more ways
to compromise system security. Industrial controllers are getting more and more connected to systems that
reside in other connectivity layers, e.g. visualizations, MES systems or even the Cloud.
