Windows ユーザーは、システムに物理的にアクセスできる攻撃者から機密データを保護するファイルシステムを望んでいます。ユーザーは次のどれを選択する必要がありますか?
正解:D
EFS (Encrypting File System) is a feature of Windows that provides filesystem-level encryption. It is designed to encrypt files and folders to protect them from unauthorized access, even if an attacker has physical access to the computer. * ext: A filesystem type used primarily in Linux, without native encryption features for Windows. * APFS: Apple's filesystem, used in macOS and iOS. * FAT: A simple filesystem type with no encryption features. * EFS: The correct choice for a Windows user needing to encrypt data at the filesystem level to protect against unauthorized physical access.
