About this tag
OT security on WindowsForum covers vulnerabilities and firmware updates for operational technology devices used in critical infrastructure such as energy, water, and manufacturing. Recent discussions highlight flaws in Siemens SICAM 8, Rockwell 1715-AENTR, Hitachi Energy e-mesh EMS and RTU500, Schneider EasyLogic T150, Hubbell Aclara meters, B&R industrial controllers, and iDirect satellite terminals. Common themes include unauthenticated remote access, credential exposure, privilege escalation, and denial-of-service risks. These threads emphasize that OT security now intersects with Windows and enterprise IT networks, requiring coordinated patch management and network segmentation. The tag is relevant for IT administrators managing hybrid environments where industrial devices share infrastructure with Windows systems.
