INFORMATION PROCESSING DEVICE WHICH CARRIES OUT RISK ANALYSIS AND RISK ANALYSIS METHOD

摘要

An information processing device includes: a unit configured to compute a service influence degree for each risk factor with respect to each service, on the basis of information which indicates a relation between components which have the risk factors and other components which are influenced by the state of the components, information which denotes characteristics of the respective risk factors, and information which denotes a correspondence between the services and these components; and a unit configured to compute, on the basis of the computed service influence degrees, similarities between specific risk factors and other risk factors, and for generating and outputting a set of component identification information on the basis of the computed similarities.

1. A risk analysis device including:
an influence degree computation unit configured to compute, on the basis of risk factor influence information representing a relation between a component having a risk factor included in a system for providing services and other components included in the system which are to be influenced by a state of said component, component characteristic information representing characteristics of each of said risk factors, and service information representing correspondence between said services and said components, a service influence degree corresponding to each of said risk factors with respect to each of said services; and a risk group generation unit configured to compute, on the basis of said service influence degrees, similarities between a specific one of said risk factors and the other ones of said risk factors, and generate and output information including at least a set of pieces of identification information each representing said component corresponding to said risk factor selected on the basis of said similarities.
