上に存在する多数の悪性 Web サイトからユーザを保護する手段として，URL ブロックリストを用いたセキュリティサービスが広く提供されている．しかし，変遷を続け多様化する悪性 Web サイトの脅威からユーザを保護するのは容易ではない．本研究では，オンライン URL 検査サービスである VirusTotal を利用して URL ブロックリストを作成・管理する既存手法を改良し，低コストで高い保護効果を実現する．具体的には，過去に悪性と判定された URL 群を URL 警告リストとして保持し，ユーザが警告リストの URL にアクセスした場合のみ再検査を行うことで， VirusTotal が保持する莫大な悪性 URL 情報を有効活用しつつ問い合わせコストを大幅に削減する．評価実験の結果，先行研究と同一の条件下で，約 85 倍の URL をリスト化し，約 9.6 倍のユーザの悪性サイトへのアクセスを防止できることを確認した．作成した警告リストを，550 名規模のアクティブユーザが存在する Web アクセスログとマッチングしたところ，最大で 1 日あたり 370 名程度のユーザを保護できることを確認した．また，作成した警告リストをセカンドオピニオンとして用いた場合に，既存のセキュリティサービスでは検知されなかった URL を 21 日間の観測期間中に累計 19, 000 件以上検知できることが確認された．このため，提案手法はユーザの保護に有効であると言える．","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"Security services

Compared to previous methods, we could collect malicious URLs from VirusTotal more than 85 times and could protect more than 9.6 times users.
