소프트웨어 보안은 보안 소프트웨어가 아닙니다. 여기서는 인증, 액세스 제어, 기밀성, 암호화, 권한 관리 등의 항목에 대해 설명합니다.

Android Bad Practices: Just Provider writePermission Defined

Abstract
이 프로그램은 writePermission만 정의된 콘텐트 공급자를 선언합니다.
Explanation
콘텐트 공급자에 대해 개별 읽기 및 쓰기 권한을 정의하는 것이 좋지만 writePermission만 정의하면 오해의 소지가 있을 수 있습니다. SQL의 특성상 진정한 쓰기 전용 쿼리를 생성하는 것은 일반적으로 불가능합니다. 사용자가 데이터에 액세스할 수 없는 경우에도 공격자는 where 절을 조작하여 저장된 데이터를 재구성할 수 있습니다.

예제: 다음은 writePermission으로만 선언된 콘텐트 공급자의 예입니다.

 <provider android:name=".ContentProvider" android:writePermission="content.permission.WRITE_CONTENT"/>
