Criticality assessment is a process that typically involves assigning assets with a criticality rating based on the effects of asset failure on a system and/or operation of the system as a whole. Presented herein are techniques that provide for the ability to incorporate network failure events in impact analysis and criticality assessment processes utilizing a five-dimensional formula, referred to herein as an Aggregated Risk Priority Number (ARPN), which can be derived using various parameters representing the severity of a network failure, the probability of occurrence of the network failure, the probability of detection of the network failure, the time of occurrence of the network failure, and a deployment knowledge factor (DKF).
