Security information
Siemens offers products and solutions with industrial security functions that support 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 comprehensive, state-of-the-art industrial security concept.
Siemens' products and solutions only form one element of such a concept. Customers are
responsible for preventing unauthorized access to their plants, systems, machines and
networks. Systems, machines and components should only be connected to the enterprise
network or the Internet if and to the extent necessary and with appropriate security measures
(e.g. use of firewalls and network segmentation) in place. Additionally, Siemens' guidance on
appropriate security measures should be taken into account. You can find more information
on industrial security at (https://www.siemens.com/industrialsecurity) .
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer's exposure to cyber threats. To
stay informed about product updates, subscribe to the Siemens Industrial Security RSS
