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。

SSH Misconfiguration: Missing Authentication

Python

Abstract

ターゲット SSH サーバーは認証を必要としません。

Explanation

機密情報やリモート管理パネルなどの特権機能が含まれるサーバーでは、アクセスに認証が必要です。そうでない場合、攻撃者は一般的なユーザー名を推測するだけで機密情報を盗んだり、ターゲットホストを制御したりすることができます。

クライアントは NoneAuth 認証方法を使用して、使用可能な認証方法を判断することができます。

例 1: 次の Paramiko コードは、「なし」認証要求を使用してサーバーに認証しようとします。


    client = SSHClient()
    client.connect(host, port, auth_strategy=NoneAuth("user"))
