OT Asset Risk Score with ot asset impact if compromised of 4.5 score: a worked example

This worked example runs the ot asset risk score numbers for a tougher week than the baseline: ot asset impact if compromised of 4.5 score instead of the typical 9 score. Rank risk for a critical OT asset using operational impact, exposure likelihood, and control or detection weakness.

The inputs for this scenario

  • OT asset impact if compromised: 4.5 score (the input this scenario stresses; the baseline uses 9)
  • OT exposure likelihood: 5 score (held at the documented default)
  • Control weakness / detection gap: 4 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: OT asset risk score = OT asset impact score × OT exposure likelihood score × control weakness score.
  • OT asset risk score works out to 4.55 score at these inputs, and this is the headline figure for the scenario.
  • OT asset impact score works out to 4.5 score at these inputs.
  • OT exposure likelihood score works out to 5 score at these inputs.
  • Control weakness score works out to 4 score at these inputs.

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 28.35% below the baseline at 4.55 score.
  • Use it to rank a fleet of OT assets for remediation, segmentation, or monitoring investment when you cannot fix everything at once. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • OT asset risk score: 4.55 score (headline result)
  • OT asset impact score: 4.5 score
  • OT exposure likelihood score: 5 score
  • Control weakness score: 4 score
