界: Encapsulation
封裝是要劃定清楚的界限。在網頁瀏覽器中，這可能意味著確保您的行動程式碼不會被其他行動程式碼濫用。在伺服器上，這可能意味著區分經過驗證的資料與未經驗證的資料、區分一個使用者的資料與另一個使用者的資料，或區分允許使用者查看的資料與不允許查看的資料。
Insecure Storage: Android World Readable or Writeable
Abstract
應用程式使資料可以由 Android 裝置上的所有應用程式存取。
Explanation
使用 MODE_WORLD_READBLE 或 MODE_WORLD_WRITEABLE 儲存於 Android 內部儲存空間的資料可由裝置上的所有應用程式存取。這不僅是拒絕防止資料損毀，且在敏感資訊的情況下違反使用者隱私權和安全性顧慮。
