界: Security Features

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。

Insecure SSL: Android Socket

Abstract
メソッドは SSL 検証チェックを行うことに失敗します。
Explanation
InetAddress を関数パラメーターとする createSocket() 呼び出しでは、ホスト名検証は行われません。

同様に、getInsecure() 呼び出しは、すべての SSL チェックを無効にしたSSL ソケットファクトリを返します。

これら両方により、アプリケーションは中間者 (Man-in-the-Middle) 攻撃を受けやすくなります。

たとえば、https://safesecureserver.banking.com に接続しようとするアプリケーションは、https://hackedserver.banking.com に発行された証明書を容易に受け入れます。これによりアプリケーションは、ハッキングされているサーバーへの不正な SSL 接続によって、機密性の高いユーザー情報をリークさせる可能性があります。
