Full packet capture is the retention of complete network packet streams so investigators can review traffic in maximal detail later. It matters because some investigations demand exact reconstruction of sessions and payload behavior, not just summary records.
What is Full Packet Capture?
This approach preserves extremely rich evidence but can be expensive, privacy-sensitive, and operationally demanding. It is often reserved for critical network segments, short-duration investigations, or high-value environments.
What Full Packet Capture Commonly Supports
Common uses include incident response, malware analysis, protocol troubleshooting, deep forensics, and high-value network monitoring.
Full Packet Capture vs. Flow Telemetry Only
Full packet capture keeps the actual packets. Flow telemetry summarizes communication patterns without retaining the full payload detail.
Frequently Asked Questions
Why use full packet capture?
Because it gives investigators the strongest chance of reconstructing exactly what happened on the wire.
What are the main tradeoffs?
Storage cost, privacy sensitivity, and operational complexity are major considerations.
