Why do OT awareness programmes miss machine identities?

TL;DR: OT awareness programmes often miss machine identities and plant-floor access patterns, Corsha argues, leaving shared logins and always-open vendor access to weaken accountability and resilience. Operational Technology Identity needs governance to keep machine connections attributable, time-bound and reviewable without slowing work.

Editorial analysis by NHI Mgmt Group, based on content published by Corsha: “title”.

Key questions

Q: Why do OT environments need identity governance instead of awareness alone?

A: Awareness changes behaviour, but it does not control machine connections, vendor pathways or standing access.

Q: How can teams tell whether OT cybersecurity awareness is actually working?

A: It is working only if operators can keep production moving while access becomes more attributable, time-bound and reviewable.

Q: What breaks when shared credentials are used for OT maintenance sessions?

A: Shared credentials break accountability and make privilege control difficult to enforce.

Practitioner guidance

  • Define OT identities and access paths Inventory every machine connection, vendor link and operational account that can affect production or safety, then assign an owner and purpose to each one.
  • Retire shared floor logins Replace shared credentials on the plant floor with attributable accounts or managed credentials so every action can be traced back to a specific identity.
  • Schedule vendor access instead of leaving it open Time-bound external access to engineering workstations, maintenance tools and control systems so access exists only during the approved task window.

Bottom line: OT cyber awareness falls short when it ignores machine identities and plant-floor access patterns.

OT awareness fails when identity is treated as an IT problem: The article shows that cybersecurity awareness programs built for office environments do not translate to plant-floor access patterns. OT risk is not only about user behaviour, but about machine connections, vendor pathways and operational accounts that carry real-world consequences. The practical conclusion is that awareness must be anchored in access governance, not generic cyber hygiene.

A question worth separating out:

Q: Should organisations prioritise automation or manual access reviews for OT security?

A: Automation should come first for recurring machine connections and vendor access because OT teams cannot sustain manual review of every session without creating friction. Manual reviews still matter for exceptions, critical changes and high-risk links, but the baseline needs continuous control. Otherwise, review cycles will always lag behind the pace of operations.
