Remote Access Risk Score with remote access impact score of 4 score: a worked example

This worked example runs the remote access risk score numbers for a tougher week than the baseline: remote access impact score of 4 score instead of the typical 8 score. Rank remote access risk using operational impact, access exposure, and control weakness.

The inputs for this scenario

  • Remote access impact score: 4 score (the input this scenario stresses; the baseline uses 8)
  • Remote access exposure score: 6 score (held at the documented default)
  • Remote access control weakness score: 5 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Remote access risk score = remote access impact score × remote access exposure score × remote access control weakness score.
  • Remote access risk score works out to 4.95 score at these inputs, and this is the headline figure for the scenario.
  • Remote access impact score works out to 4 score at these inputs.
  • Remote access exposure score works out to 6 score at these inputs.
  • Remote access control weakness score works out to 5 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where remote access impact score sits at 8 score and the headline result is 6.55 score, this scenario comes in 24.43% below the baseline at 4.95 score.
  • Use it when ranking and prioritizing vendor, integrator, and engineer remote access routes into a control network for hardening or removal. 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

  • Remote access risk score: 4.95 score (headline result)
  • Remote access impact score: 4 score
  • Remote access exposure score: 6 score
  • Remote access control weakness score: 5 score
