Zero Trust Security in OT is a cybersecurity approach that assumes no user, device, or system should be trusted by default. It requires continuous verification of access rights and enforces strict authentication measures for every network interaction.
This security model minimizes attack surfaces by implementing least-privilege access, micro-segmentation, and multi-factor authentication (MFA). By securing industrial assets at every level, Zero Trust prevents unauthorized access to critical operational technology (OT) systems.
As cyber threats targeting industrial environments increase, adopting Zero Trust Security in OT helps industries reduce risks, prevent lateral movement of malware, and maintain resilience against cyberattacks while ensuring uninterrupted operations.
