Abstract
A log analysis apparatus extracts a parameter from an access log under analysis, acquires a similarity by comparing the parameter with the parameter included in the profile stored in a profile storage unit, and determines an access in the access log under analysis as an attack when the similarity is lower than a threshold. The log analysis apparatus takes a tally of the number of different requesting user terminals, for each parameter, among the access logs under analysis including a parameter not found in the profile, or having a similarity lower than the threshold, and determines, when there is any parameter for which the number of such different user terminals is equal to or higher than a threshold, to re-learn the parameter.
