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. rewalls and/or network segmentation) are in place.
For additional information on industrial security measures that may be implemented, please

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.
