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.
