Executive Summary

Risk analysis is a key component on the path to developing a risk model for a system. Risk analysis enables the user to balance security against cost by understanding specific risks to the system as a whole from threats to the availability, integrity and confidentiality of its assets. Risk is the probability of loss in a system. The basic goal of risk analysis is to compute an overall level of risk that can serve as a basis of decision-making or for initiating a countermeasure. An effective method for combination of risk value would be to use a fuzzy logic approach to compute overall risk. This can be used for the combination of risk values at several stages of the risk analysis process.
