Training Course on Network Device Forensics

Training Course on Network Device Forensics

Introduction

In the evolving digital threat landscape, Network Device Forensics has become an indispensable part of cybersecurity investigations. Organizations depend on routers, switches, and firewalls for seamless communication and protection, making these network devices a prime target for cyberattacks. Training Course on Network Device Forensics equips cybersecurity professionals, network engineers, and IT investigators with the skills to analyze, interpret, and investigate digital artifacts within critical infrastructure components. The course highlights the importance of deep-packet inspection, firmware analysis, configuration audits, and log correlation to uncover indicators of compromise and persistent threats.

This course is designed with the latest forensic techniques, industry best practices, and compliance standards such as NIST, ISO 27001, and MITRE ATT&CK. It prepares learners to recognize malicious behaviors hidden within network traffic, retrieve and preserve logs from routers and firewalls, and trace back attacks using network telemetry. From device-level evidence acquisition to chain-of-custody documentation, participants will learn to support both internal security operations and legal proceedings with defensible forensic analysis.

Course Objectives

1. Understand the fundamentals of network forensics and packet-level analysis.
2. Identify forensic artifacts from router logs and switch memory dumps.
3. Apply deep-packet inspection (DPI) techniques to detect anomalies.
4. Analyze and correlate firewall logs to reconstruct attack paths.
5. Perform configuration file audits for security misconfigurations.
6. Conduct firmware reverse engineering to detect tampering.
7. Develop strategies for incident response and threat attribution.
8. Implement network monitoring and logging best practices.
9. Create forensic reports for internal audits and legal evidence.
10. Use open-source and commercial tools for device forensics.
11. Understand compliance with GDPR, HIPAA, and NIST standards.
12. Utilize SIEM integration for correlating network data.
13. Demonstrate chain of custody and data integrity in forensic investigations.
