Network forensics can be defined as the sniffing, recording, acquisition and analysis of the network traffic and event logs in order to investigate a network security incident.

The provided statement is a correct and comprehensive definition of network forensics. This discipline involves the systematic capture, recording, and analysis of network traffic and associated data, such as event logs. The primary objective is to investigate security incidents, identify attack vectors, determine the extent of a compromise, and gather evidence for potential legal action. The terms "sniffing," "recording," and "acquisition" accurately describe the data collection phase, while "analysis" refers to the examination of that data to reconstruct events.

B. False: This option is incorrect. The statement accurately encapsulates the core activities, data sources, and purpose of network forensics as defined in authoritative academic and technical literature.

In Section 2, "Network Forensics," the authors define the discipline as "the process of capturing, recording and analyzing the network packets in order to determine the source of network security attacks." This directly supports the definition given in the question.

In the introduction (Section 1), the paper states, "Network forensics is a sub-domain of digital forensics that mainly deals with the examination of network traffic data for forensic investigation... It involves capturing, storing, and analyzing network packets that pass through a computer network." This aligns with the question's definition. DOI: https://doi.org/10.1007/s42979-019-0013-1

3. University of Illinois, CS 461: Computer Security I, Lecture 23: Network Security & Forensics. Course materials often define network forensics as the capture, storage, and analysis of network data. The process involves monitoring network traffic to detect intrusions and analyzing captured data (e.g., packet captures, logs) to investigate the scope and origin of an attack, which validates the components mentioned in the question's definition.
