# Analyzing Network Traffic with Wireshark
## When to Use
- Investigating suspected network intrusions by examining packet-level evidence of command-and-control traffic, data exfiltration, or lateral movement
- Diagnosing network performance issues such as retransmissions, fragmentation, or DNS resolution failures
- Analyzing malware communication patterns by capturing traffic from sandboxed or isolated hosts
- Validating firewall and IDS rules by confirming what traffic is actually traversing network segments
- Extracting files, credentials, or indicators of compromise from captured network sessions
**Do not use** to capture traffic on networks without authorization, to intercept private communications without legal authority, or as a substitute for full-featured SIEM platforms in production monitoring.
## Detection Gaps & Validation
- **You only see what the tap delivers:** a SPAN port that mirrors one direction, or oversubscription dropping frames, makes beaconing look intermittent. Confirm with `tshark -r cap.pcapng -q -z io,phs` and check the capture's dropped-packet count before concluding traffic is absent.
