Also, they can use viruses to put backdoors into target sites. Security scanners which are commonly used for security assessment cannot detect such risks described above, because they can just enumerate vulnerabilities. In this paper, we propose a vulnerability assessment tool, which can simulate whole possible activities taken by attackers. This is achieved by applying an inference engine based on first-order predicate logic to decide attack scenarios.}, title = {一階述語論理を用いた脆弱性診断ツール}, year = {2002} }
