4 Security
To secure plants, systems, machines and networks against cyberthreats it is necessary to
implement (and continuously maintain) an overall industrial security concept that is state of
the art.
Perform a risk assessment in accordance with VDI/VDE 2182 or IEC 62443-3-2 and plan
the security measures with care. If necessary, seek advice from Pilz Customer Support.
