Published: 19 October 2022


MicrosoftによるWindows 11のリリースは多くの企業にとって想定外の事象であったと同時に、多くのIT担当者がWindows 11のセキュリティに関心を寄せている。本リサーチノートでは、企業のセキュリティ/リスク・マネジメントのリーダーが知っておくべきWindows 11およびそのセキュリティについてのトレンドと推奨事項について述べる。

Included in Full Research


  • Gartnerが2022年3月日本国内の企業を対象に実施した調査では、Windows 11の導入率は13.3%であった。多くの企業においては計画の見直しを迫られるなどの混乱が見られ、Windows 11への移行になかなか踏み切れていない。

  • 多くの企業は、Widnows 11のセキュリティの何が良いのか、これまでと何が違うのかといった全体像をつかめずにいる

  • 仮想デスクトップ・インフラストラクチャ (VDI) やサービスとしてのデスクトップ (DaaS)、クライアント・クラウドなど、エンドユーザー環境には物理PC以外にもさまざまなタイプがあり、何を選択すべきか判断に迷う組織が増えている。


セキュリティ/リスク・マネジメント (SRM) のリーダーは、以下を行う。

  • Windows 10のサポートが切れる前にWindows 11への移行を完了させられるよう、今からロードマップの見直しと移行計画の作成に着手する。

  • Windows 11のセキュリティを短絡的に過信するようなメッセージからは距離を置き、今回改善されたセキュリティ機能が自社の脅威環境に対してどのようなメリットをもたらすのかを具体的に評価する場を設ける。

  • 物理PC、VDIあるいはDaaSを検討する際には、企業として唯一の形を選ぶのではなく、ユーザーのユースケースに応じて使い分ける。
