界: Encapsulation

カプセル化とは、強い境界線を引くことです。Web ブラウザの場合は、自分のモバイルコードが他のモバイルコードに悪用されないようにすることを意味します。サーバー上では、検証されたデータと検証されていないデータ、あるユーザーのデータと別のユーザーのデータ、またはユーザーが見ることを許可されたデータと許可されていないデータの区別などを意味する場合があります。

Android Bad Practices: Encryption Secret Held in Static Field

Java/JSP

Abstract

アプリケーションは暗号鍵を静的クラスフィールドに保持し、攻撃者はこれを簡単に発見してしまいます。

Explanation

静的クラスフィールドに暗号鍵を保持すると、プロセスメモリ (ルート化されたデバイスなど) やプロセスメモリダンプ (クラッシュダンプなど) にアクセスできるエンティティによって簡単に発見されてしまいます。
