The SOC receives an alert from a network sensor showing an internal host communicating with a known malicious IP over HTTPS. The analyst cannot find any process making outbound connections on the host. What should the analyst do next?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check for hidden processes or rootkits using specialized tools
Option D is correct because the absence of a visible process suggests the presence of a rootkit or hidden process that requires deep analysis. Other options may be premature or incomplete.
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.
✗
Capture a memory dump of the host
Why it's wrong here
Memory capture is useful but should be done after checking for hidden processes.
✗
Block the IP at the firewall
Why it's wrong here
Blocking the IP does not address the potential rootkit on the host.
✓
Check for hidden processes or rootkits using specialized tools
Why this is correct
Hidden processes can be detected by tools like rootkit revealers, addressing the anomaly.

Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
