ISO 27001 and one-way data paths: strengthening ISMS evidence without shortcutting controls

Beyond policy documents

An ISMS lives in risk assessment, treatment plans, and operational proof. For organisations bridging OT data into corporate analytics, the recurring risk is covert bidirectional access disguised as “monitoring.” Directional hardware collapses that discussion for nominated flows.

Architecture patterns auditors recognise

Clear trust zones, documented data owners, and explicit transfer approval pair well with a diode segment whose sole role is to publish curated operational data outward. The PDF outlines representative architectural overlays against 27001-flavoured control language.

Stay precise

No appliance “grants” ISO 27001 certification. Position the diode as part of your control suite with evidence—logs, change records, and scope boundaries—not slogans.
