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

Exhibit

Refer to the exhibit.
Oct 12 14:23:45 server sshd[1234]: Failed password for root from 192.168.1.200 port 22 ssh2
Oct 12 14:23:47 server sshd[1234]: Failed password for root from 192.168.1.200 port 22 ssh2
Oct 12 14:23:49 server sshd[1234]: Failed password for root from 192.168.1.200 port 22 ssh2
Oct 12 14:23:51 server sshd[1234]: Failed password for root from 192.168.1.200 port 22 ssh2

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

⚠ Common exam trap

Candidates often confuse a brute force attack with a dictionary attack, but the key differentiator is the exhaustive, non-selective nature of the attempts versus the use of a precompiled wordlist.

Answer choices

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.

The exhibit shows a high number of failed authentication attempts (e.g., 1000+ failures) from a single source IP within a short time window, targeting a specific user account. This pattern is characteristic of a brute force attack, where an attacker systematically tries many password combinations to gain unauthorized access. Unlike a dictionary attack, which uses a predefined list of likely passwords, a brute force attack exhaustively tests all possible combinations, as indicated by the sheer volume of attempts.

Answer analysis

Option-by-option breakdown

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

  • Denial of service.

    Why it's wrong here

    DoS attacks aim to overwhelm services, not repeatedly authenticate.

  • Brute force attack.

    Why this is correct

    Multiple rapid failed attempts for the same user from one IP is characteristic of brute force.

  • Dictionary attack.

    Why it's wrong here

    Dictionary attacks use a wordlist, but the logs do not show patterns of many different passwords; brute force is more general.

  • Man-in-the-middle.

    Why it's wrong here

    MITM attacks intercept communications; failed SSH logins do not indicate this.
