|**security information**<br>~~|~~|||
|security information<br>~~|~~|Siemens provides products and solutions with industrial cybersecurity functions<br>that support the secure operation of plants, systems, machines and networks.<br>In order to protect plants, systems, machines and networks against cyber<br>threats, it is necessary to implement - and continuously maintain - a holistic,<br>state-of-the-art industrial cybersecurity concept. Siemens’ products and<br>solutions constitute one element of such a concept. Customers are responsible<br>for preventing unauthorized access to their plants, systems, machines and<br>networks. Such systems, machines and components should only be connected<br>to an enterprise network or the internet if and to the extent such a connection is<br>necessary and only when appropriate security measures (e.g. firewalls and/or<br>network segmentation) are in place. For additional information on industrial<br>cybersecurity measures that may be implemented, please visit<br>www.siemens.com/cybersecurity-industry. Siemens’ products and solutions<br>undergo continuous development to make them more secure. Siemens strongly<br>recommends that product updates are applied as soon as they are available<br>and that the latest product versions are used. Use of product versions that are<br>no longer supported, and failure to apply the latest updates may increase<br>customer’s exposure to cyber threats. To stay informed about product updates,<br>subscribe to the Siemens Industrial Cybersecurity RSS Feed under<br>https://www.siemens.com/cert.(V4.7)<br>~~|~~||
