About this tag
Windows OT security covers the protection of operational technology (OT) systems that run on Windows-based engineering workstations, protocol simulators, and industrial gateways. Recent discussions on WindowsForum.com highlight vulnerabilities in products from Siemens, Hitachi Energy, ABB, and AVEVA, including credential exposure, denial of service, remote code execution, and insecure defaults. These threads emphasize that Windows OT security is not just about traditional IT threats but also about the unique risks in industrial environments, such as unauthenticated PLC discovery and SQL injection in ICS software. The tag focuses on practical lessons for defenders managing Windows OT assets in sectors like energy, manufacturing, and water treatment.
