Network forensics is fundamentally concerned with the process of capturing, recording, and analyzing network traffic. This discipline involves various techniques to monitor data flowing over a network, which allows for the investigation of incidents, identification of security breaches, and gathering of evidence in a manner that is legally admissible. The core activities include sniffing or intercepting packets, recording the data for evidence, and performing an in-depth analysis to understand the nature of traffic, potential breaches, and staff or system behavior during an incident.

While social media monitoring, forensic data recovery from physical devices, and the analysis of physical devices are important in their own right, they do not capture the essence of network forensics. The focus on network traffic specifically distinguishes this field from other forensic practices, making the first option the most accurate definition of network forensics. Thus, this option encapsulates the key aspects of data acquisition and analysis central to understanding network-related incidents.
