Security concepts and communication
The PCS 7 security concepts described in the document "PCS 7 Compendium Part F - Industrial
Security" must be observed for secure operation of the system.
You can find additional information on this document in the table above under "PCS 7".
In particular, we recommend the following:
• Protection of the devices/systems, e.g. PCS 7 OS server and clients
• Ensuring the integrity and confidentiality of communication between the devices/systems,
e.g.:
– By means of encrypted and authenticated communication between the systems involved,
– When using Industrial Ethernet CPs: by means of a VPN tunnel between the OS systems

such as the PCS 7 OS system and/or between engineering stations (ES)
and/or automation systems (AS).
