2  Safety 
2.1  Cyber security disclaimer 
Siemens provides a portfolio of products, solutions, systems and services that 
includes security functions that support the secure operation of plants, systems, 
machines and networks. In the field of Building Technologies, this includes building 
automation and control, fire safety, security management as well as physical 
security systems. 
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 
security concept. Siemens’ portfolio only forms one element of such a concept. 
You are responsible for preventing unauthorized access to your plants, systems, 
machines and networks which 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. Additionally, Siemens’ guidance on appropriate security measures should be 
taken into account. For additional information, please contact your Siemens sales 
representative or visit https://www.siemens.com/global/en/home/company/topic-
areas/future-of-manufacturing/industrial-security.html. 
Siemens’ portfolio undergoes continuous development to make it more secure. 
Siemens strongly recommends that updates are applied as soon as they are 
available and that the latest versions are used. Use of versions that are no longer 
supported, and failure to apply the latest updates may increase your exposure to 
cyber threats. Siemens strongly recommends to comply with security advisories on 
the latest security threats, patches and other related measures, published, among 
others, under https://www.siemens.com/cert/en/cert-security-advisories.htm.
