About this tag
Legacy operational technology, including PLCs and SCADA systems, presents persistent cybersecurity challenges in manufacturing environments. As IT/OT convergence and remote access expand, these decades-old systems become exposed in ways they were never designed for. Discussions on WindowsForum emphasize that protecting legacy OT requires approaches that prioritize availability, safety, and long life cycles, rather than treating them like modern IT assets. The tag covers securing long-lived industrial plants, addressing blind spots in connected factories, and applying frameworks like NIST and ISA guidance to legacy operational technology.

    Legacy OT Cybersecurity: Securing PLCs, SCADA, and Long-Lived Plants

    Legacy operational technology is no longer a quiet liability tucked away on the factory floor; it has become one of manufacturing’s most persistent cybersecurity blind spots. As ESET frames it, the problem is not that old machines are inherently broken, but that decades-old OT increasingly sits...
