  • 巧妙化するランサムウェアの脅威は増大しており、世界中の犯罪組織や政府組織が攻撃を行っている。

  • あらゆるバックアップ・ベンダーが、ランサムウェアとの戦いに役立つように自社製品を適応させ、強化しているが、ランサムウェア攻撃から組織を完全に保護できる単独のソリューションは存在しない。

  • バックアップ・ストレージの不変性、バックアップ・システムへの安全なログイン、重要なシステム構成変更の単独権限の削除といった機能は、攻撃からバックアップ・システムを保護するために重要である。

  • 最新のバックアップ・アプリケーションとマルウェア・スキャンの利用により、ランサムウェア攻撃を早期に検知する。

  • 最新のバックアップ機能を確実に使用することで、バックアップ・システムを保護する。これには、多要素認証 (MFA)、CIFS (Common Internet File System) などのシンプルなネットワーク共有プロトコルの排除、管理の役割の分離が含まれる。

  • ランサムウェア攻撃発生時に、ベンダーによって強化されたリカバリ機能を使用することで、クリーンで安全なリカバリ・プロセスを確保する。
