Read MoreZero Trust – A Virtual Air Gap for OT Security
Air-gapping computer and operational technology (OT) networks is a long-established method of protecting sensitive information and reducing the risk of operational disruption. A growing trend has been to provide connectivity from these networks to the Internet for remote monitoring and control, real-time data, data analysis, predictive maintenance, improving inventory and resource management, achieving faster decision-making,…
Read MoreZero 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…
