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: Missing exported Flag or Component Permission
Abstract
このプログラムは、コンポーネントにアクセス許可を明示的に割り当てません。
Explanation
すべてのアプリケーションが、マニフェスト定義でアクセス許可が明示的に割り当てられていないパブリック コンポーネントにアクセスできます。android:minSdkVersion または android:targetSdkVersion を "16" またはそれ以前に設定するアプリケーションの場合、Android コンテンツ プロバイダーはデフォルトでエクスポートされます。これらの属性のいずれかを "17" またはそれ以降に設定するアプリケーションの場合、デフォルトは "false" です。
例 1: 明示的なアクセス権限もエクスポートされたフラグもなしで宣言された Android コンテンツプロバイダの例を次に示します。
例 1: 明示的なアクセス権限もエクスポートされたフラグもなしで宣言された Android コンテンツプロバイダの例を次に示します。
<provider android:name=".ContentProvider"/>
