界: Encapsulation

封装即绘制强边界。在 Web 浏览器中，这可能意味着确保您的移动代码不会被其他移动代码滥用。在服务器上，这可能意味着区分已验证数据和未验证数据、区分一个用户的数据和另一个用户的数据，或者区分允许用户查看的数据和不允许用户查看的数据。

Insecure Storage: HTTP Response Cache Leak

Abstract

所述方法将 HTTP(S) 响应缓存安装在不安全的共享存储中。

Explanation

HTTP(S) 响应中可能包含敏感数据，例如会话 Cookie 和 API 标记。出于性能方面的考虑，URL 加载系统会对所有 HTTP(S) 响应进行缓存，将它们以未加密的形式存储在不安全的共享存储中。

示例 1： 以下代码将 HTTP(S) 响应缓存安装在共享存储空间：


    protected void onCreate(Bundle savedInstanceState) {
       ...

       try {
           File httpCacheDir = new File(context.getExternalCacheDir(), "http");
           long httpCacheSize = 10 * 1024 * 1024; // 10 MiB
           HttpResponseCache.install(httpCacheDir, httpCacheSize);
       } catch (IOException e) {
           Log.i(TAG, "HTTP response cache installation failed:" + e);
       }
    }

    protected void onStop() {
       ...

       HttpResponseCache cache = HttpResponseCache.getInstalled();
       if (cache != null) {
           cache.flush();
       }
   }
