~~rr~~|| |security information|Siemens provides products and solutions with industrial cybersecurity 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 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.
