Zero Trust for OT Security – Shields Up vs Damage Report

In the original and newer Star Trek episodes and movies, the captain would order “shields up” or “raise shields” prior to an attack to prevent damage to the USS Enterprise. The shields were some sort of force field of which the physics is never fully described. During or after an attack the captain would request…
