Check Text (C-268556r1034608_chk)
Verify the macOS system is configured to enforce FileVault with the following command:
dontAllowDisable=$(/usr/bin/osascript -l JavaScript << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.MCX')\
.objectForKey('dontAllowFDEDisable').js
EOS
)
fileVault=$(/usr/bin/fdesetup status | /usr/bin/grep -c "FileVault is On.")
if [[ "$dontAllowDisable" == "true" ]] && [[ "$fileVault" == 1 ]]; then
echo "1"
else
echo "0"
fi
If the result is not "1", this is a finding.
