About this tag
The NIST ISA 62443 tag on WindowsForum.com covers discussions around securing operational technology (OT) in industrial environments, with a focus on standards from NIST and the ISA/IEC 62443 series. Content highlights the challenges of protecting legacy PLCs, SCADA systems, and long-lived plants as IT/OT convergence and remote access expose them to modern cyber threats. Key themes include balancing availability, safety, and long life cycles in OT security, rather than applying traditional IT approaches. The tag is relevant for professionals dealing with industrial cybersecurity, compliance, and risk management in manufacturing and critical infrastructure.
