Overview What You Will Learn Curriculum Instructor

Course Overview

Network Forensic analysis is a sub-domain in the broad spectrum of digital forensics used for retrospective analysis of networks to find pieces of evidence left behind following a cyberattack. It analyses network traffic to gather the information that could connect security teams to the threat actor, find vulnerabilities exploited to enter the network, and so on. It is a hard task because of your huge amount of data and the large number of protocols and tools currently available.

In the current scenario, most incidents involve technological devices that are connected to a local or external network, and for criminals to be identified, it is essential you know or has people in your organization capable of interpreting the traces left at a crime scene virtually. The course begins with a hands-on approach to the network of the theory taught in many schools, with the instructor explaining RFCs using Wireshark. Further, you will learn open-source tools to analyze some network attacks, like Security Onion, Wazuh, and Arkami. Finally, you will learn how to detect a Cobalt Strike attack.

Network Forensics also involves proactive monitoring and analysis of network traffic for anomalous behavior, intrusion detection, incident response, and vulnerability management. With increasing network traffic and network systems complexity, the need for network forensics is expected to continue to grow significantly.

The course aims to offer some techniques and tools so that the members of a blue team can analyze cyber incidents by finding the evidence left on the network by the attackers.
