Risk Management Scoring Description

Description The calculations in Risk Management scoring is explained below

Risk Scoring Calculations The inherent and residual scores for a risk are calculated using the risk criteria, likelihood, and impact. Use the following calculations to score risks. • Qualitative Inherent ALE = Inherent ARO x Inherent SLE • Qualitative Inherent Score = Inherent Likelihood x Inherent impact • Quantitative Residual ALE = Residual ARO x Residual SLE • Qualitative Residual Score = Residual SLE When scoring is set to qualitative, the quantitative values are updated in the background. The Calculated Score for a risk is a read-only field designed to quickly assess a risk affecting the organization, and identify threats and areas of non-compliance. If controls are implemented to mitigate risk, then Calculated ALE = Residual ALE + ((Inherent ALE - Residual ALE) * (Calculated Risk Factor / 100)). Thus Calculated Score = Residual Score only if Compliance with the controls is 100%. If the Calculated Score > Residual Score, the organization is not 100% compliant with the controls used to mitigate a risk. Meaning that the Calculated Score can never be less than the Residual Score or greater than the Inherent Score. If controls are not implemented to mitigate risk, then Calculated Score = Residual Score. If the Residual Score is not set, then Calculated Score = Inherent Score. The calculated risk factor value is calculated as Calculated Risk Factor = (Indicator failure factor + Control failure factor) / 2 Control failure factor -> Sum of failed controls weighting divided by total controls weighting. Indicator failure factor -> Uses the last result of each associated indicator. Number of last results failed divided by total number of indicators associated. Applicable Versions J and above
