セキュリティ アナリストが会社の認証ログを確認し、複数の認証エラーに気づきました。認証の失敗は、同じ送信元 IP アドレスを共有する別のユーザー名によるものです。最も起こりそうなパスワード攻撃はどれですか?
正解:C
Explanation Detailed Explanation: Password spraying is an attack where an attacker tries a small number of commonly used passwords against a large number of usernames. The goal of password spraying is to avoid detection by avoiding too many failed login attempts for any one user account. The fact that different usernames are being attacked from the same IP address is a strong indication that a password spraying attack is underway.
