계: Encapsulation
캡슐화는 강력한 경계를 그리는 것입니다. 웹 브라우저에서는 사용자의 모바일 코드가 다른 모바일 코드에 의해 오용되지 않도록 하는 것을 의미합니다. 서버에서는 검증된 데이터와 검증되지 않은 데이터, 한 사용자의 데이터와 다른 사용자의 데이터, 데이터 사용자가 볼 수 있는 데이터와 볼 수 없는 데이터 간의 차별화를 의미할 수 있습니다.
Insecure Storage: Android Backup Storage
Abstract
이 프로그램은 Android의 백업 서비스를 사용하여 영구 응용 프로그램 데이터를 원격 클라우드 스토리지에 저장합니다.
Explanation
Android의 백업 서비스를 사용하면 응용 프로그램이 원격 클라우드 스토리지에 영구 데이터를 저장하여 향후에 응용 프로그램 데이터의 복원 지점을 제공할 수 있습니다.
Android 응용 프로그램을 이 백업 서비스로 구성하려면
그러나 Android에서는 클라우드 스토리지 및 전송이 장치마다 다르기 때문에 백업을 사용하는 동안 데이터 보안이 보장되지 않습니다.
Android 응용 프로그램을 이 백업 서비스로 구성하려면
allowBackup 속성을 true(기본값)로 설정하고 <application> 태그에서 backupAgent 속성을 정의하면 됩니다.그러나 Android에서는 클라우드 스토리지 및 전송이 장치마다 다르기 때문에 백업을 사용하는 동안 데이터 보안이 보장되지 않습니다.
