Network forensics is defined as which of the following?

• A. Social network analysis
• B. Email header analysis
• C. Forensic analysis of hard drives
• D. Sniffing, recording, acquisition and analysis of network traffic and event logs

Answer: (D)

The main idea is examining data in transit and the related logs to investigate and reconstruct network-based incidents. Network forensics focuses on capturing, recording, acquiring, and analyzing network traffic and event logs from devices like routers, switches, firewalls, and servers, as well as endpoints, so you can trace what happened, when it happened, and how an intrusion or outage occurred. This includes sniffing or packet capture, preserving evidence to maintain integrity, and analyzing traffic patterns, headers, and logs to build a timeline and identify sources and methods used. The other options don’t fit because social network analysis looks at relationships and interactions in social networks rather than technical network data; email header analysis is a specialized area within email forensics dealing with metadata of email messages; and forensic analysis of hard drives is computer or digital forensics focused on stored data rather than network activity.
