Title:
ATTACK PATH ESTIMATION SYSTEM, ATTACK PATH ESTIMATION DEVICE, ATTACK PATH ESTIMATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/223668
Kind Code:
A1
Abstract:
One aspect of an attack path estimation system according to the present disclosure is an attack path estimation system that estimates attack paths in a target system, the attack path estimation system having: a configuration information creation unit configured to use at least either design information or an operational history log of the target system to create configuration information representing the configuration of the target system; a predicted path information creation unit configured to use the configuration information and attack patterns anticipated in the target system to create predicted path information representing predicted paths of attacks on the target system; a predicted path information creation unit configured to use a log acquired from the target system and prescribed weighting conditions to create weighted predicted path information in which weightings have been applied to the predicted path information when an attack has been detected on the target system; and a path search unit configured to estimate attack paths representing paths from the origin of the attack to an attack destination by using a path search on the weighted predicted path information.
