OT

Operational technology and industrial control systems — pipelines, water utilities, manufacturing floors, building automation. CISA and TSA advisories, plus NIST SP 800-82r3, are the language regulators and auditors speak here. Attention is triggered when a remote-access pivot reaches a human-machine interface, when an engineering workstation is found exposed, or when a sector-wide campaign hits an OT vendor that a critical facility depends on.
