Abstract
プログラムは、受信者の権限を指定せずにブロードキャストを送信しています。
Explanation
受信者の権限を設定せずに送信されたブロードキャストはすべての受信者がアクセスできます。これらのブロードキャストに重要なデータが含まれる、あるいは不正な受信者にアクセスする場合には、アプリケーションが危険にさらされる可能性があります。

例 1: 次のコードは、受信者の権限を指定せずにブロードキャストを送信しています。

Abstract
このレシーバー コンポーネントは、システムおよび他のコンポーネントからメッセージを受信するように登録されています。
Explanation
システム ブロードキャストはプライベート コンポーネントに送信できます。サードパーティからの非システム ブロードキャストを受信するには、コンポーネントをパブリックにする必要があります。システム ブロードキャストと非システム ブロードキャストの両方を単一のコンポーネントで受信するように登録すると、コンポーネントの機能の一部 (システム部分) が不必要にサードパーティに公開されます。

Abstract
このプログラムは、normal 保護レベルで権限を宣言します。
Explanation
カスタム権限を宣言する場合、権限の保護レベルを指定するための 4 つのオプションがあります: normaldangeroussignature、および signature or systemNormal 権限は、それらを要求するすべてのアプリケーションに付与されます。Dangerous 権限は、ユーザーの確認後にのみ付与されます。Signature 権限は、権限を定義するパッケージと同じ開発者キーによって署名されたアプリケーションにのみ付与されます。Signature or system 権限は signature 権限と似ていますが、Android システム イメージのパッケージにも付与されます。

例 1:normal 保護レベルで宣言されたカスタム権限の例を次に示します。

 <permission android:name="custom.PERMISSION"
android:label="@string/label_permission"
android:description="@string/desc_permission"
android:protectionLevel="normal">
</permission>

Abstract
このプログラムは、読み取りアクセスと書き込みアクセスの permission を組み合わせて、コンテンツ プロバイダーを宣言します。
Explanation
読み取りと書き込みの permission を組み合わせて宣言されたコンテンツ プロバイダーには、そのプロバイダーに読み取りまたは書き込みアクセスを要求するエンティティがアクセスできるようになります。しかし、多くの場合、ファイル システム上のファイルの場合と同様に、プロバイダーによって保存されたデータへの読み取りアクセスを必要とするエンティティに、データの変更を許可すべきではありません。permission 属性を設定した場合、データ ユーザーとデータの整合性に影響を与える相互作用を区別できません。

例 1: 読み取りおよび書き込みを組み合わせたアクセス permission をコンテンツプロバイダで宣言した例を次に示します。

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

Abstract
プログラムが Sticky ブロードキャストを送信しています。
Explanation
Sticky ブロードキャストは、権限を設定してセキュリティを確保することはできないため、あらゆる受信者がアクセスできるようになります。これらのブロードキャストに重要なデータが含まれる、あるいは不正な受信者にアクセスする場合には、アプリケーションが危険にさらされる可能性があります。

例 1: 次のコードは、Sticky ブロードキャストを使用しています。

Abstract
プログラムは、android.permission 名前空間に新しい権限を定義します。
Explanation
android.permission 名前空間に新しい権限を定義すると、OS の更新時に予期しない結果が発生する場合があります。新しいバージョンの OS がまったく同じ権限を定義すると、Android Package Management Service (PMS) は、ユーザーに確認することなく、アプリに対してサイレントに権限を付与するため、権限昇格攻撃のチャンスを与えることになります。

Abstract
このレシーバー コンポーネントには、サードパーティのコンポーネントから不必要なアクセスを行うことが可能であり、悪意のある情報が注入されるリスクを高めます。
Explanation
このコンポーネントは、システムからブロードキャスト メッセージを受信することのみを想定しています。他のコンポーネントからの受信は想定していないため、プライベートにする必要があります (他のコンポーネントからはアクセスできません)。
