Attack pattern extraction device, attack pattern extraction method, and attack pattern extraction program

摘要

The attack pattern extraction device (10) has an extraction unit (13a) and an attack pattern generation unit (13b). The extraction unit (13a) extracts a common character string of parameters in the access log of the communication determined to be an attack. Then, the attack pattern generation unit (13b) generates an attack pattern based on a character string having a character string length equal to or greater than a predetermined character string length among the extracted continuous character strings.
