  • セキュリティ/リスク・マネジメント (SRM) のリーダーは、従来のシグネチャ・ベースのエンドポイント・セキュリティに依存しており、ファイルレス攻撃、ランサムウェア、アイデンティティ窃取に対する防御に苦戦している。こうした攻撃を受けて、企業の脆弱性は高まる。リスク評価と攻撃状況のアセスメントは、エンドポイント・セキュリティを強化し、企業がさらなる攻撃を受けないようにする上での前提となる。

  • ほとんどの企業は、さまざまな成熟度のツールを組み合わせて採用している。しかし企業は、すべてのセキュリティ・ツールにわたってアラートのトリアージ、調査、対応を調整できるよう、包括的なセキュリティ・オペレーション (SecOps) とインシデント対応 (IR) のテクノロジを必要としている。



  • まず、成熟度評価の前提条件となるものの導入から始める。それには、エンドポイントの検知/対応 (EDR) ツールを使用した挙動検知の改善、リスク評価と攻撃状況のアセスメントの実施が含まれる。

  • エンドポイントの成熟度を高めるロードマップを作成し、エンドポイントのセキュリティの現在のレベルと、保護および運用の効率を改善するために必要なステップを分析する。このロードマップは、セキュリティ・ポスチャをアセスメントし、各成熟度レベルの重要な要素、特に成熟度をさらに高めるための優先的なプロジェクトの要件が、組織の環境から抜け落ちないようにするのに役立つ。
