The best next step is to investigate if the IP address is associated with known malicious activity. This is correct because the IT risk identification process requires validating whether an observed event constitutes a genuine threat before escalating or responding. By checking the external IP against threat intelligence feeds like VirusTotal or AlienVault OTX, you determine if it is part of a known botnet or brute-force campaign, which characterizes the risk event rather than jumping to action. On the CRISC exam, this tests your understanding that risk identification is about gathering evidence to confirm a threat, not immediate remediation—a common trap is choosing to block the IP or reset the password right away. Remember the memory tip: “Identify before you deny”—always verify the threat source first to align with the CRISC risk identification phase.
CRISC IT Risk Identification Practice Question
This CRISC practice question tests your understanding of it risk identification. 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 SOC analyst observes repeated failed login attempts from an external IP address targeting a user account. What is the best next step in the IT risk identification process?
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
✓
Investigate if the IP address is associated with known malicious activity
Option C is correct because the first step in the IT risk identification process is to validate whether the observed event represents a genuine threat. Investigating the external IP address against threat intelligence feeds (e.g., VirusTotal, AlienVault OTX) confirms if it is associated with known malicious activity, such as a botnet or brute-force campaign, before taking any action. This aligns with the CRISC risk identification phase, where the goal is to characterize the risk event, not immediately respond or escalate.
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.
✗
Block the IP address immediately
Why it's wrong here
Blocking without analysis may be premature and could disrupt legitimate traffic.
✗
Conduct a vulnerability scan of the target system
Why it's wrong here
A vulnerability scan is not directly relevant to the failed login event; it focuses on system weaknesses.
✓
Investigate if the IP address is associated with known malicious activity
Why this is correct
Checking the IP against threat intelligence helps identify whether this is a known attacker, informing risk assessment.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Escalate to the incident response team
Why it's wrong here
Escalation is appropriate after confirming a malicious intent, not as a first step.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ISACA often tests the distinction between risk identification and risk response, trapping candidates who jump to blocking or escalation without first validating the threat through investigation.
Detailed technical explanation
How to think about this question
Failed login attempts generate Windows Security Event ID 4625 or Linux auth.log entries, which should be correlated with external threat intelligence via APIs (e.g., STIX/TAXII) to check the IP's reputation score. In a real-world scenario, a SOC analyst might find the IP belongs to a known C2 server or a Tor exit node, confirming the risk; conversely, it could be a misconfigured VPN concentrator causing repeated authentication failures, which would change the risk profile entirely.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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 practitioner preparing for the CRISC exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
