This infographic explains how managing vulnerabilities in operational technology (OT) within manufacturing differs from traditional IT approaches. OT environments prioritize safety, reliability, and continuous uptime, making patching infrequent and often disruptive due to legacy systems and limited maintenance windows. It highlights three common manufacturing OT vulnerabilities affecting Rockwell Automation PLCs and Mitsubishi Electric electrical discharge machines, with the most urgent being CVE-2023-21554 due to active exploitation and available proof-of-concept. Dragos promotes a risk-based “NOW, NEXT, NEVER” framework that adjusts CVSS scores for OT realities, focusing on operational impact, exploitability, and alternative mitigations such as restricting services, segmentation, MFA, an
