Understanding Network Forensics

Network forensics involves capturing, recording, and analyzing network traffic to discover the source of security attacks or other problem incidents. Unlike traditional forensics that focuses on static artifacts, network forensics deals with dynamic, ephemeral data that requires different collection and analysis approaches.

Key Objectives of Network Forensics:

Identifying attack vectors and methodologies
Detecting data exfiltration and theft
Reconstructing attacker communications
Understanding lateral movement patterns
Validating security control effectiveness
Supporting incident timeline reconstruction
