The correct choice is to check the SIEM for correlated events. This is the best immediate action because a Security Information and Event Management system aggregates logs from multiple sources, allowing an analyst to see if the failed login attempts are part of a broader pattern—such as a brute-force attack, credential stuffing, or reconnaissance—before taking any disruptive measures like blocking the IP. On the Systems Security Certified Practitioner SSCP exam, this scenario tests your understanding of the incident response process, specifically the principle of “verify before you act,” and the importance of context over reaction. A common trap is jumping to block the IP immediately, which could lock out a legitimate user or miss a coordinated attack. For a memory tip, think “SIEM first, block last”—always correlate before you isolate.
SSCP Risk Identification, Monitoring and Analysis Practice Question
This SSCP practice question tests your understanding of risk identification, monitoring and analysis. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security analyst notices an increase in failed login attempts from a single IP address. What is the best immediate action?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the SIEM for correlated events.
Checking the SIEM for correlated events (Option D) is the best immediate action because it allows the analyst to gather context around the failed login attempts—such as whether they target multiple accounts, originate from a known malicious IP, or coincide with other suspicious activity—before taking a potentially disruptive or irreversible step. This aligns with the incident response principle of 'verify before you act,' ensuring the response is proportional and informed by correlated data from multiple sources.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Run an antivirus scan.
Why it's wrong here
Antivirus scans are for malware detection, not for investigating failed login attempts.
✗
Disable the user accounts.
Why it's wrong here
Disabling accounts is drastic and may impact productivity; it should only be done if the accounts are confirmed compromised.
✗
Block the IP at the firewall.
Why it's wrong here
Blocking immediately may disrupt legitimate traffic if the IP is not malicious; correlation is needed first.
✓
Check the SIEM for correlated events.
Why this is correct
The SIEM can correlate multiple events to determine if the IP is part of a larger attack or a false positive.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose 'Block the IP at the firewall' (Option C) as the fastest immediate action, but the SSCP exam emphasizes that the first step in incident response is to gather and correlate evidence to confirm the threat before taking potentially disruptive actions.
Detailed technical explanation
How to think about this question
SIEM platforms like Splunk or ELK correlate logs from firewalls, authentication servers (e.g., RADIUS, LDAP), and IDS/IPS using timestamped events and fields such as source IP, destination port, and account name. A single IP generating failed logins might indicate a password spraying attack (RFC 7617) or a dictionary attack, and the SIEM can reveal if the IP is also triggering IDS alerts or scanning other ports, enabling a risk-based decision before applying a firewallACL or rate-limiting rule.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
