界: Encapsulation

カプセル化とは、強い境界線を引くことです。Web ブラウザの場合は、自分のモバイルコードが他のモバイルコードに悪用されないようにすることを意味します。サーバー上では、検証されたデータと検証されていないデータ、あるユーザーのデータと別のユーザーのデータ、またはユーザーが見ることを許可されたデータと許可されていないデータの区別などを意味する場合があります。

Insecure Storage: Android World Readable or Writeable

Java/JSP

Abstract

アプリケーションは Android デバイス上のすべてのアプリケーションのデータにアクセス可能です。

Explanation

MODE_WORLD_READBLE または MODE_WORLD_WRITEABLE を使用して Android 内部ストレージに格納されたデータは、デバイス上のすべてのアプリケーションからアクセス可能です。これはデータ破壊からの保護を否定するだけでなく、機密情報の場合、ユーザーのプライバシーとセキュリティに関する懸念に反することとなります。
