How it's worked out

  • Likelihood = average of 8 factors; impact = average of 4 factors. Levels: under 3 low, 3 to under 6 medium, 6 to 9 high. Severity from the 3 × 3 matrix
  • Factor scores 0 to 9 from the OWASP guidance
NoteWhere business impact is known, use it instead of technical impact, as the method recommends.
