Training Course on Advanced Network Traffic Analysis (PCAP Analysis)

Training Course on Advanced Network Traffic Analysis

Introduction

In today’s cybersecurity landscape, Advanced Network Traffic Analysis is a critical skill for identifying and mitigating sophisticated threats. Training Course on Advanced Network Traffic Analysis focuses on PCAP (Packet Capture) analysis, a foundational technique for understanding and interpreting network behavior. By diving deep into PCAP files using industry-standard tools like Wireshark, tcpdump, and Zeek, participants will gain hands-on expertise in analyzing network traffic, detecting anomalies, and tracing malicious activity with precision.

Designed for cybersecurity professionals, analysts, and IT engineers, this course integrates real-world case studies, cutting-edge techniques, and threat intelligence to transform raw packet data into actionable insights. Whether you're monitoring network performance, identifying threats, or responding to incidents, this training equips you with the analytical and technical skills required in today’s zero-trust, threat-hunting, and SOC-driven environments.

Course Objectives

1. Master the fundamentals and structure of PCAP files using Wireshark and tcpdump.
2. Identify anomalies, intrusions, and malware through deep packet inspection (DPI).
3. Correlate threat behavior using MITRE ATT&CK and kill chain models.
4. Apply network forensics techniques to real-time and historical traffic.
5. Analyze encrypted traffic and understand limitations and decryption techniques.
6. Perform incident response by interpreting log data and packet behavior.
7. Detect C2 (Command and Control) communications in PCAP traces.
8. Use Zeek (Bro) and Suricata for high-performance traffic analysis.
9. Build detection rules and threat indicators (IOCs) from raw traffic.
10. Integrate PCAP analysis into SIEM and EDR workflows.
11. Evaluate network segmentation, VLANs, and tunneling protocols.
12. Perform timeline reconstruction for attack investigations.
13. Document findings in a forensic report with clear evidence chain.
