Abstract
In order to detect an attack to a web application accurately by accurately correlating different types of events having occurred in the same server, an event acquiring unit acquires a log of events containing a HTTP request to a server, an event correlator creates a set of the request and events relevant to the request as an event block by using process IDs of processes having processed events contained in the log, and an attack detector contrasts the event block that is created from the log of events in which an attack is to be detected with an event block that is created from normal events to calculate a degree of similarity and, when the degree of similarity is equal to or lower than a threshold, detects the event block as an event block containing an event that is abnormal due to an attack.
