Ensure FileVault Is Enabled

높음레벨 1자동macos

설명

FileVault secures a system's data by automatically encrypting its boot volume and requiring a password or recovery key to access it. FileVault should be used with a saved escrow key to ensure that the owner can decrypt their data if the password is lost. FileVault may also be enabled using command line using the fdesetup command. Audit: Requires FileVault On and the com.apple.MCX dontAllowFDEDisable profile key (the benchmark requires the profile).

EOS
)
if printf '%s' "$s" | /usr/bin/grep -q "FileVault is On" && [ "$p" = true ]; then echo compliant; else echo "$s dontAllowFDEDisable=${p:-unset}"; fi
