# 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.

## Prerequisites

- Wireshark 4.0+ and tshark command-line utility installed
