- Skills Covered / Tools Used
- Tool Mastery: Gaining expert proficiency with the Wireshark interface, including customizing layouts, profiles, and preference settings for optimal analysis workflow.
- Advanced Capture Control: Implementing sophisticated capture filters (BPF syntax) to target specific traffic, utilize ring buffers for continuous monitoring, and manage multiple capture interfaces simultaneously.
- Display Filter Wizardry: Crafting complex display filters using logical operators, string matching, regular expressions, and protocol-specific fields to isolate and pinpoint relevant data within large capture files.
- Protocol Deep Dive: Dissecting and understanding the intricacies of various application-layer protocols (e.g., HTTP/2, FTP, SMTP, SSH, DNS, DHCP) and how they interact with lower layers.
- Performance Analysis: Identifying network bottlenecks, latency issues, retransmissions, duplicate ACKs, and windowing problems using Wireshark’s advanced statistical tools and expert information system.
- Security Incident Response: Detecting suspicious activity, identifying reconnaissance attempts, locating unencrypted credentials, analyzing potential malware communication patterns, and uncovering C2 (command and control) traffic.
- HTTPS Decryption Techniques: Practically applying methods to decrypt TLS/SSL encrypted traffic, including leveraging pre-master secret logs from web browsers to analyze secure web communications.
- Troubleshooting Common Issues: Diagnosing connectivity problems, application errors, DNS resolution failures, DHCP lease issues, ARP related problems, and routing complexities by examining packet flow.
- Network Forensics: Extracting files (e.g., images, executables) and objects transmitted over HTTP or SMB from capture files for further analysis.
- Traffic Generation & Manipulation: Understanding how various tools can generate or manipulate traffic (e.g., for ARP spoofing scenarios) and how Wireshark can detect such activities.
- I/O Graph Interpretation: Generating and interpreting I/O graphs, throughput graphs, and jitter analysis to visualize network performance trends over time.
