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。
Cross-Site Scripting: Untrusted HTML Downloads
Abstract
停用設定為
noopen 的 X-Download-Options 標頭，允許下載的 HTML 頁面在網站向其提供的安全環境中執行。Explanation
當網站必須能夠為使用者提供下載時，開啟這些下載的選項意味著在瀏覽器中執行的任何已提供檔案都可以在與該網站相同的安全環境中，於目前瀏覽器中開啟。
如果攻擊者能夠操縱下載的檔案，便可插入在瀏覽器中執行的 HTML 或指令碼來充當 Cross-site scripting 攻擊，從而竊取或操縱目前階段作業中的資訊。
範例 1：以下範例明確停用了針對在瀏覽器中執行的已提供下載的防護。
