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。
Android Bad Practices: Encryption Secret Held in Static Field
Abstract
應用程式在靜態類別欄位中保留加密金鑰，讓攻擊者能夠輕鬆復原。
Explanation
在靜態類別欄位中儲存加密金鑰讓可存取程序記憶體 (例如，取得 Root 權限的裝置) 或程序記憶體傾印 (例如，損毀傾印) 的實體能夠輕鬆復原。
