  • Publication number: 20220311786
    Abstract: Provided is an analysis system that can analyze the degree of impact of vulnerability on individual systems. An analysis unit 6 generates an attack pattern that includes an attack condition, an attack result, an attack means that is vulnerability that is used by an attack, and a segment where the attack can occur in a system to be diagnosed. A calculation unit 12 calculates an evaluation value, for each vulnerability, which indicates degree of impact of the vulnerability on the system to be diagnosed. Specifically, the calculation unit 12 calculates the evaluation value, for each vulnerability, based on the number of the attack patterns that include the vulnerability focused on as the attack means and the number of the segments indicated by each attack pattern that includes the vulnerability focused on as the attack means.
