TMA-ANDROID-ENCRYPTION
Ensure device storage encryption is active
Deskripsi
Android 10+ devices ship with file-based encryption enabled by default; older or modified devices can be unencrypted. ro.crypto.state reports encrypted when FBE/FDE is active. The audit uses adb against the single attached device (set ANDROID_SERIAL when several are connected) and FAILS when adb is missing or no authorised device is connected. adb requires USB debugging, so disable Developer options again after the audit.
Cara pemeriksaan
Metode audit: Perintah shell
out=$(adb shell getprop ro.crypto.state 2>/dev/null) || exit 1
state=$(printf '%s' "$out" | tr -d '\r[:space:]')
if [ "$state" = encrypted ]; then echo compliant; else echo "ro.crypto.state=${state:-unset}"; fi- Output yang diharapkan
compliant
Cara perbaikan
Metode perbaikan: Panduan atau patch infrastruktur
Devices shipping Android 10+ are encrypted by default; if ro.crypto.state is not 'encrypted' (custom ROM, unlocked bootloader or legacy device) back up, relock the bootloader / reflash stock firmware or retire the device. Legacy devices: Settings > Security > Encrypt phone. EMM: Android Management API policy encryptionPolicy=ENABLED_WITH_PASSWORD.
