OT Asset Risk Score with ot asset impact if compromised of 23 score: a worked example

This scenario runs the ot asset risk score calculation on the strong side: ot asset impact if compromised of 23 score, with every other input held at its documented default. Use it when prioritizing protection work for PLCs, HMIs, SCADA servers, DCS nodes, historians, or engineering workstations.

The inputs for this scenario

  • OT asset impact if compromised: 23 score (raised for this scenario; the documented default is 9)
  • OT exposure likelihood: 5 score (unchanged)
  • Control weakness / detection gap: 4 score (unchanged)

Working through the calculation

  • Applying the documented formula (OT asset risk score = OT asset impact score × OT exposure likelihood score × control weakness score) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.95 score for ot asset risk score, the number this scenario is built around.
  • At this operating point the engine returns 23 score for ot asset impact score.
  • At this operating point the engine returns 5 score for ot exposure likelihood score.
  • At this operating point the engine returns 4 score for control weakness score.

How this compares with the baseline

  • Against the tool's baseline example, where ot asset impact if compromised sits at 9 score and the headline result is 6.35 score, this scenario comes in 88.19% above the baseline at 11.95 score.
  • Use it to rank a fleet of OT assets for remediation, segmentation, or monitoring investment when you cannot fix everything at once. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • OT asset risk score: 11.95 score (headline result)
  • OT asset impact score: 23 score
  • OT exposure likelihood score: 5 score
  • Control weakness score: 4 score
