ATTACK PATTERN EXTRACTION APPARATUS, ATTACK PATTERN EXTRACTION METHOD, AND ATTACK PATTERN EXTRACTION PROGRAM

摘要

An attack pattern extraction apparatus (10) has: an extraction unit (13a); and an attack pattern generation unit (13b). The extraction unit (13a) extracts character strings common among parameters in a communication access log determined as being an attack. The attack pattern generation unit (13b) generates an attack pattern on the basis of a character string, the length of which is equal to or longer than a prescribed character string length, among the extracted continuous character strings.
