Reino: Security Features

La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.

Privilege Management: Android Data Storage

Java/JSP

Abstract

El programa solicita permiso para escribir datos en el almacenamiento externo de Android.

Explanation

Los archivos escritos en almacenamiento externo son legibles y los programas y usuarios arbitrarios pueden escribir en ellos. Los programas nunca deben escribir información confidencial en un almacenamiento externo; por ejemplo, información de identificación personal. Cuando conecta el dispositivo Android a través de USB a un PC u otro dispositivo, se habilita el modo de almacenamiento masivo USB. Cualquier archivo escrito en un almacenamiento externo se puede leer y modificar en este modo. Además, los archivos del almacenamiento externo permanecerán allí incluso después de que se desinstale la aplicación que los escribió, lo que aumenta aún más el riesgo de que cualquier información confidencial almacenada en ellos se vea comprometida.

Ejemplo 1:El elemento <uses-permission .../> de AndroidManifest.xml declara el uso del permiso de WRITE_EXTERNAL_STORAGE, que permite a una aplicación introducir datos en un almacenamiento externo.

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Ejemplo 2: El elemento <uses-permission .../> de AndroidManifest.xml declara el uso del permiso de READ_EXTERNAL_STORAGE, que permite a una aplicación leer en un almacenamiento externo.

 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
