DETECTION DEVICE AND DETECTION PROGRAM

Document Type and Number:

WIPO Patent Application WO/2020/075330

Kind Code:

A1

Abstract:

A normalization unit (11) changes URIs of logs pertaining to access to a plurality of web servers, into normalized URIs by standardizing similar notations between the multiple URIs. A calculation unit (12) calculates, among access logs having the same transmission source, the percentage of access logs having prescribed response codes with respect to identical normalized URIs having different addresses. When the maximum value of the percentage calculated for each of the normalized URIs is equal to or greater than a threshold value, a determination unit (13) determines such a normalized URI to be subject to scanning.
