Message Processing Engine RBP Algorithm

Weights are between 0 and 100.

The MPE RBP formula is RBP = (CRRp + ERRp + DRTp + STLp) / MaxPossibleRiskPoints * 100.

• CRRp. Classification Risk Points. Class Relative Risk Rating * Class Weight
• ERRp. Event Risk Rating Points. Event Risk Rating * Risk Rating Weight
• DRTp. Destination Risk Rating Points. Destination Risk Threshold Points * DRT Weight
• STLp. Source Threat Rating Points. Source Threat Threshold Points * STL Weight
• MaxPossiblePoints = (ClassWt * MAX_CRR) + (EventWt * MAX_ERR) + (STLWt * MAX_STL) + (DRLWt * MAX_DRL)
  • Here, MAX_CRR = MAX_ERR = MAX_STL = MAX_DRL = 9
