|**security information**<br>~~a~~|||||
|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. To stay informed about product updates,||
||||subscribe to the Siemens Industrial Cybersecurity RSS Feed under||
