Usage for the intended purpose
IT security and rules for the use of Ethernet devices
The plant operator is responsible for the security of his/her IT network and must take appropriate action to
protect equipment, systems and components from unauthorised access.
Pay attention to the following instructions when using Ethernet devices in your system:
■
Do not connect equipment, systems or components to an open network, such as the internet, without
safeguards in place.
■
To fully protect a PLC runtime system on a control system that is available on the internet, the use of
common security mechanisms (firewall, VPN access) is absolutely essential.
■
Make sure access to all components is restricted to authorised persons.
■
Change default factory passwords before bringing into service for the first time!
■
Deploy defence in depth mechanisms in your system security, to restrict access and control to individ-
ual products and networks.
