Abstract

A determination apparatus includes a keyword extraction unit that extracts keywords characterizing a vulnerability from known vulnerability information, and a 0-day attack determination unit that compares the keywords characterizing the vulnerability and keywords included in a request used for an attack, and when a value of a score indicating a degree of inclusion of same keywords as the keywords characterizing the vulnerability in the request is smaller than a predetermined threshold, determines that the request is a 0-day attack that is neither a known attack nor an attack similar to the known attack.
