Note on firmware/software support
Check regularly for new firmware/software versions or security updates and apply them. After
the release of a new version, previous versions are no longer supported and are not
maintained.
-party software components that are no longer supported.
Therefore, Siemens can no longer ensure that the firmware/software does not contain any
known security
-critical vulnerabilities.
Siemens will provide software updates for the CP until the official end of the software support
(date not yet known). This entails examining new vulnerabilities that could also affect the CP,
correcting such vulnerabilities and/or providing instructions on how to eliminate or mitigate
the vulnerabilities. However, due to possible missing vulnerability information relating to the
t
hird-party software that is no longer supported, these measures are incomplete.
For this reason, Siemens recommends the following supplementary measures when using
the CP:
Keep an eye on the Security Advisories that could have effects on the CP
Always use the latest firmware version of the CP
Protect additional access to the Internet with suitable additional measures and
components, such as SCALANCE S
Implement a state-of-the-art security concept for your entire network.

Security information
Siemens provides products and solutions with industrial security 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
security 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.
