SSCP Practice Question: Based on the exhibit, which type of attack is…

Exhibit

Refer to the exhibit.

[user@server ~]$ sudo cat /var/log/auth.log | grep 'Failed password' | tail -5
Mar 10 14:23:01 server sshd[1234]: Failed password for root from 10.0.0.5 port 22 ssh2
Mar 10 14:23:05 server sshd[1234]: Failed password for root from 10.0.0.5 port 22 ssh2
Mar 10 14:23:09 server sshd[1234]: Failed password for root from 10.0.0.5 port 22 ssh2
Mar 10 14:23:13 server sshd[1234]: Failed password for root from 10.0.0.5 port 22 ssh2
Mar 10 14:23:17 server sshd[1234]: Failed password for root from 10.0.0.5 port 22 ssh2

Based on the exhibit, which type of attack is most likely occurring?

⚠ Common exam trap

Many exam-takers confuse a brute force attack with a denial of service attack because both can generate high volumes of traffic, but the key differentiator is the repeated authentication failure pattern versus resource exhaustion.

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Brute force attack

A brute force attack is most likely occurring because the exhibit shows repeated login attempts with different passwords for the same username, which is the hallmark of an automated password guessing attack. The rapid succession of failed authentication events indicates a systematic trial of credentials, not a single intercepted session or resource exhaustion.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Brute force attack

    Why this is correct

    Repeated failed password attempts from same IP is classic brute force.

  • Man-in-the-middle attack

    Why it's wrong here

    MITM would not generate auth.log entries like this.

  • Denial of service attack

    Why it's wrong here

    DoS would show resource exhaustion, not repeated login attempts.

  • Social engineering attack

    Why it's wrong here

    Social engineering is not directly observable in logs.
