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 cybersecurity 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
cybersecurity measures that may be implemented, please visit
www.siemens.com/cybersecurity-industry. 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. To stay informed about product updates,
