Presentation Title The Art of Network Forensics
Presentation Abstract

Network forensics is defined as the capture, recording, and analysis of network events in order to discover the source of security attacks or other problem incidents.

In other words, it involves capture, preservation, analysis and presentation of network traffic. This talk will present the principle, knowledge and tools that are needed in order to adopt and apply the best practices of network-based forensics. We will present how network-forensics can complement host-based forensics for effective investigations of digital computer crime. In this lab session, we will introduce almost all the latest open source network forensics tools that are currently available and its offerings. A “crime scene investigation”-like apparoach will be applied, we will show how a forensic investigator can extract evidence from packet capture, create network event timeline, reconstruct and reassemble network sessions, analyze network flow and discover hidden communication channels.
