1.6.1 Security 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 constitute one element of
such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the Internet if and to the extent such a connection
is necessary and only when appropriate security measures (e.g. firewalls and/or network
segmentation) are in place.
For additional information on industrial security measures that may be implemented,
please visit (https://www.siemens.com/industrialsecurity
).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they
are available and that the latest product versions are used. Use of product versions that
are no longer supported, and failure to apply the latest updates may increase customer's
exposure to cyber threats.
