Included in Full Research


  • 企業は、資産管理、構成管理、変更管理、ライセンス管理ツールを使って資産に関する情報を収集しているが、脆弱性マネジメントに必要な情報の連携がなされていない

  • 企業においてはクラウドや外部サービスの活用が進み、脆弱性マネジメントの対象は増加しているが、それに合わせた脆弱性に関する情報の収集がルール化されていなかったり、ルールはあっても形骸化していたりするそのため他社で発生したインシデントのニュースをきっかけとして情報収集を開始する、といった場当たり的な対応が取られているのが実情である

  • セキュリティ部門が収集した脆弱性の危険性に関する情報や、それらが自社のシステムに及ぼす影響の度合いを、システムや端末を管理している開発・運用部門が理解できなかったり、管理対象と責任の定義が曖昧であるために脆弱性の放置や修正の遅れが発生したりしている。


セキュリティ/リスク・マネジメント (SRM) のリーダーは、以下を実施する。

  • 脆弱性マネジメント管理する対象と項目を明確にするために、資産管理ツールや管理者が作成したスプレッドシート上に散在しているシステムの名称、ミドルウェア、バージョン、メンテナンス・スケジュールなどの情報を集約し、一元管理を開始する。

  • 脆弱性マネジメントの対象の拡大と脆弱性マネジメント・テクノロジの進化を踏まえ脆弱性に関する情報収集をルール化し、タイムリーかつ抜けや漏れがないものにするために、ツールやサービス活用に向けて再評価を実施する

  • 脆弱性の放置や修正の遅れをなくすために、関係者全体でリスクに応じた対応目標を共有し、合意を形成する。
