Title:
INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/193958
Kind Code:
A1
Abstract:
The present invention comprehensively extracts attack paths that are hypothesized in a target system, and derives an attack example (including attack content and countermeasure, for instance) for each device allowing the establishment of each attack path. An information processing device D includes: an input unit 1 that reads a list of a group of devices included in the system and a list of inter-device connection relationships; an attack path extraction unit 2 that extracts an attack path on the basis of the list of the group of devices and the list of connection relationships read by the input unit 1; an attack example DB unit 3 that associates a past attack example with an attack purpose and a node condition from when the attack example occurred, and stores the result; an attack example search unit 4 that determines an attack purpose and a node condition for each device serving as each node that makes up the attack path extracted by the attack path extraction unit 2, uses the determined attack purposes and the determined node conditions to search the attack example DB unit 3, and acquires attack examples corresponding to each device; and an output unit 5 that outputs the search results.
