Safety information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines, and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
The customer is responsible for preventing unauthorized access to its plants, systems,
machines and networks. Systems, machines and components should only be connected to
the enterprise network or the Internet if necessary and only to the extent necessary and with
appropriate protective measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens' guidelines on appropriate security measures should be observed.
For more information about industrial security, please visit
Industrial security (http://www.siemens.com/industrialsecurity)
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends applying product updates as soon as they are
available and always using the latest product versions. Using versions that are obsolete or
are no longer supported can increase the risk of cyber threats.
