Safety Precautions and Technical Details

GENERAL INSTRUCTIONS FOR SAFE OPERATION
2.12 IT and data security
Direct access to the production network should be protected by a firewall and hence
according to the current IT security standards. Nevertheless, it is the operator’s
responsibility to verify that the measures taken in the existing network are sufficient.
External data storage media as well as maintenance and service devices represent
basic security risks. These devices should be scanned for viruses before they are
used.
Only software that is required for production is installed on the controller. Installation
of additional software is not permitted.
Only network connections that are necessary, secure, and have been selected for
the production process (e.g., for remote maintenance) may be set up on the control-
ler. Unrestricted internet access to the controller must be prevented.
Additional protection can be achieved by network segmentation (e.g., by separating
the production network from the office network) to prevent mutual interference.
Modifications to the operating system are not permitted.
