An attack pattern extraction device includes an extraction unit and an attack pattern generation unit. The extraction unit extracts a common character string of parameters included in an access log of communication that is determined as an attack. The attack pattern generation unit generates an attack pattern on the basis of a character string with a string length being equal to or longer than a predetermined length among extracted consecutive character strings.
