Industrial cybersecurity
1.1 Introduction to 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.
Refer to the SIMATIC S7-1500/ET 200MP automation system
(https://support.industry.siemens.com/cs/ww/en/view/59191792) System Manual for general
information and measures regarding industrial cybersecurity.
This section provides an overview of security-relevant information pertaining to your
SIEMENS device.
1.2 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.
For more information on protective industrial cybersecurity measures for implementation,
please visit (https://www.siemens.com/global/en/products/automation/topic-areas/industrial-
cybersecurity.html).
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.
