Abstract
A risk analyzer analyzing risk of a system including N (natural number greater than or equal to 2) elements connected includes: an inputter receiving, as inputs, a cost of each N element for increasing a safety degree against a threat to security, a connection relationship of at least part of the N elements, an entry point being an element serving as an entry to the system, and a defense target being an element protected in the system; an identifier identifying, based on the cost of each N element and the connection relationship, a target element of one or more elements requiring a minimum total cost necessary for cutting off a target path from the entry point to the defense target by increasing a safety degree of one or more elements on the target path to a threshold value or more; and an outputter outputting element information indicating the target element.
