ソフトウェアのセキュリティは、セキュリティ ソフトウェアではありません。ここでは、認証、アクセス制御、機密性、暗号化、権限管理などのトピックについて説明します。

Android Bad Practices: Just Provider writePermission Defined

Abstract
このプログラムは、writePermission のみが定義されているコンテンツ プロバイダーを宣言します。
Explanation
コンテンツ プロバイダーに対して読み取り権限と書き込み権限を個別に定義することをお勧めしますが、writePermission のみを定義すると誤解を招く可能性があります。SQL の性質上、真の書き込み専用クエリを生成することは一般的に不可能です。ユーザーがデータに直接アクセスできない場合でも、攻撃者が where 句を操作して保存されたデータを再構築する可能性があります。

例 1:writePermission のみを使用して宣言されたコンテンツプロバイダの例を次に示します。

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