200-201 Question 132
Single answerA security analyst at an organization is investigating a potential data exfiltration incident. They decide to use full packet capture to analyze the network traffic. Which of the following is the primary benefit of using full packet capture in this scenario?
- A
It allows examination of the payload of network packets to identify the content of communications.
- B
It automatically blocks malicious traffic identified in the captured packets.
- C
It provides a summary of network traffic, including metadata, without storing the full packet data.
- D
It helps the analyst visualize traffic patterns through pre-generated dashboards.
Show answer and explanation
Correct answer: A
Explanation
Full packet capture is a critical forensic tool in cybersecurity, as it allows analysts to store and inspect the complete network traffic, including headers and payloads. This makes it especially useful for detailed investigations like identifying the content of potentially exfiltrated data. While other tools may provide summaries or automated responses, full packet capture focuses on providing a complete historical record for in-depth analysis.
- A. Correct.
Full packet capture stores the complete contents of network packets, including payloads, which enables analysts to investigate the content of communications during an incident.
- B. Incorrect.
Full packet capture does not automatically block traffic; it is a forensic tool used for post-incident analysis.
- C. Incorrect.
Summarizing traffic metadata is a function of network flow analysis (e.g., NetFlow), not full packet capture.
- D. Incorrect.
Visualization of traffic patterns is typically achieved with SIEM tools or traffic analysis platforms, not through the raw data stored in full packet capture.
