Computer Hacking Forensic Investigator (CHFI) Practice Exam

Network forensics primarily allows investigators to inspect network traffic and logs, which involves capturing and examining data packets as they traverse the network. This process enables investigators to analyze communication patterns, identify anomalies, and reconstruct events leading up to a security incident. By scrutinizing both incoming and outgoing traffic, network forensics plays a crucial role in understanding the nature of attacks, determining the extent of data breaches, and gathering evidence that can support legal action or organizational policy changes.

In this context, analyzing network traffic can reveal critical information about the timing and methods used in an attack, which is essential for creating a timeline of events and identifying potential vulnerabilities in the network. Logs from routers, switches, and firewalls serve as valuable resources for monitoring how data flows through the network and for uncovering unauthorized activities.

While the other choices relate to various aspects of cybersecurity and forensic investigation, they do not specifically encapsulate the primary function of network forensics. For instance, analyzing malware signatures is focused on detecting and identifying malicious software rather than monitoring network activity. Recovering deleted files relates to data recovery, which is a different forensic process. Scanning for vulnerabilities involves assessing a system's defenses but does not entail the real-time tracking and logging of network traffic and user behavior, which is
