200-201 Security Monitoring Practice Question
An organization uses Zeek for network monitoring. An analyst wants to extract files transferred over HTTP from network traffic. Which Zeek script or functionality should they use?
⚠ Common exam trap
200-201 often tests the confusion between Zeek's logging capabilities and its file extraction functionality, causing candidates to select log types that only provide metadata rather than actual file contents.
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
✓
Zeek's file extraction script
Zeek's file extraction script (often the File Analysis Framework or specific scripts like extract-all-files) is designed to identify and extract files from network traffic, including those transferred over HTTP. This functionality allows analysts to reconstruct files for further inspection, such as malware analysis.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Zeek's connection log
Why it's wrong here
The connection log records five-tuple flow summaries — source, destination, ports, bytes, duration — with no application-layer payload. It is tempting because it shows HTTP sessions, but it captures transport metadata only; file extraction needs the file-analysis framework, which reassembles and hashes HTTP response bodies.
- ✗
Zeek's HTTP log
Why it's wrong here
The HTTP log records request metadata — methods, URIs, headers, status codes — but not response bodies, so transferred file content is never captured. It is tempting because it is the HTTP-specific log, yet extraction requires the file-analysis framework, which hashes and writes files to disk via its extract hook.
- ✓
Zeek's file extraction script
Why this is correct
Zeek's file extraction framework reconstructs files from HTTP sessions by reassembling stream data and writing payloads to disk, satisfying the requirement to extract transferred files from captured traffic. It handles MIME types and connection tracking natively, so no packet-level manual carving is needed.
- ✗
Zeek's DNS log
Why it's wrong here
The DNS log records queries, responses and record types, containing no HTTP payload data at all. It is tempting as a Zeek log for network visibility, but DNS analysis addresses name resolution, not file transfer; the file-analysis framework extracts HTTP bodies by MIME type and writes them to disk.
