Functional safety and security: Holistic approach for a secure last line of defense

(in lingua inglese)

HIMA explains why plant operators should implement a holistic functional safety approach that ensures plant security in times of increasing cybercrime. A holistic approach to security should cover the core SIS, including final control elements, logic solver, and I/O module and sensors. It should also extend to the SIS environment, including the engineering station, asset management tools (AMS), handhelds, and field entry panels and HMIs.
