In previous works [2, 4] we have introduced a formal risk assessment method and we have shown its mathematical properties. The method allows to model a system as a structured set of vulnerabilities, each one potentially depending on the others: the goal of the method is to consider the influence of the dependencies and, thus, to provide a global risk assessment. A crucial point is the use of order-based metrics to measure the exploitability of a threat: orderbased metrics reduce the subjective aspects in the risk evaluation process. This work extends the previous ones by showing how to combine the risk evaluations performed by different experts whose degree of expertise may vary.
