The Nessus scanner monitors data at rest, while the PVS monitors data in motion. True or False?

The statement is true because it accurately describes the functions of the Nessus scanner and the PVS (Passive Vulnerability Scanner). Nessus is primarily employed for vulnerability assessments and scans data that is stored, or "at rest," on systems, focusing on identifying vulnerabilities and configuration issues that could be exploited if someone accessed that data. It performs thorough scanning on static data to highlight potential security risks.

On the other hand, the PVS operates by monitoring data as it flows through the network or "in motion." This tool captures real-time traffic and analyzes it to identify potential vulnerabilities and security threats as they occur in the network, rather than examining the stored information. This capability allows organizations to respond to threats in real-time, enhancing their security posture by understanding the dynamics of their network.

This delineation of roles in the monitoring of data highlights why the statement is accurate, as it distinctly identifies the operational focus of both Nessus and PVS in the realm of cybersecurity assessment.
