In automation world, cyber components control the machinery or the physical portion. Examples of machinery are turbine, passenger lift, vehicle, vessel, aircraft, vehicle, entry control etc.

I have seen certain cyber security practitioners who solely put focus on the cyber part and ignore the physical part. That’s no ideal.

We MUST treat both portions with sufficient protection and good operating conditions. If the components are very cyber secure while the physical wear and tear conditions are ignored, this is just like the “operation is successfully but the patient is dead”.
