Wireshark Network Traffic Analysis

Purpose

Execute comprehensive network traffic analysis using Wireshark to capture, filter, and examine network packets for security investigations, performance optimization, and troubleshooting. This skill enables systematic analysis of network protocols, detection of anomalies, and reconstruction of network conversations from PCAP files.

Inputs / Prerequisites

Required Tools

Wireshark installed (Windows, macOS, or Linux)
Network interface with capture permissions
PCAP/PCAPNG files for offline analysis
Administrator/root privileges for live capture

Technical Requirements

Understanding of network protocols (TCP, UDP, HTTP, DNS)
Familiarity with IP addressing and ports
Knowledge of OSI model layers
Understanding of common attack patterns

Use Cases

Network troubleshooting and connectivity issues
Security incident investigation
Malware traffic analysis
Performance monitoring and optimization
Protocol learning and education

Outputs / Deliverables

Primary Outputs

Filtered packet captures for specific traffic
Reconstructed communication streams
Traffic statistics and visualizations
Evidence documentation for incidents
