Wireshark Network Traffic Analysis

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. Begin capturing packets on network interface: Apply filters before capture to limit data collection: Filter captured packets for analysis: Filter by specific protocols: Identify specific connection states: Search for specific content: Identify potential issues: Use logical operators for complex queries: View complete TCP conversation: View protocol distribution: Analyze communication pairs: View active network participants: Visualize packet sequence: Plot traffic over time: Identify reconnaissance activity: Filter for anomalies: Identify ARP attacks: Analyze file transfers: Investigate DNS activity: View Wireshark's automated findings: Scenario : Investigate potential plaintext credential transmission Finding : Credentials transmitted in cleartext form data. Scenario : Identify command and control traffic Indicators : Scenario : Diagnose slow web application Finding : TCP retransmissions indicating network congestion. - Wireshark installed (Windows, macOS, or Linux) - Network interface with capture permissions - PCAP/PCAPNG files for offline analysis...
