About this tag
The ics security tag on WindowsForum covers industrial control system vulnerabilities and advisories from CISA and vendors like Siemens, ABB, Delta, and KMW. Discussions focus on Modbus TCP flaws in PLCs, authenticated file upload risks in protection relays, unauthenticated password-reset bugs in CCTV cameras, denial-of-service attacks on industrial networking gear, and XXE vulnerabilities in NSA GRASSMARLIN. Recurring themes include the gap between IT and OT security practices, the operational impact of patching industrial devices, and the importance of network segmentation. The tag is relevant for professionals managing critical infrastructure, substations, manufacturing, or energy environments.
