Industrial cybersecurity
Due to the digitalization and increasing networking of machines and industrial plants, the risk
of cyber attacks is also growing. Appropriate protective measures are therefore mandatory,
particularly in the case of critical infrastructure facilities.
In the first part of this section you will find basic information on the subject of industrial
cybersecurity. In the following sections, measures for the entire system and individual
components are recommended to protect against manipulation and unwanted access.
NOTE
Security-relevant changes to software or devices are documented in the section New
properties/functions (Page 38).
3.1 Cybersecurity 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.

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 customers' exposure to
cyber threats.
