Final answer:
The statement is false; Nessus is a vulnerability scanner that identifies known weaknesses in systems and applications, not specifically data at rest, while NNM monitors network traffic, meaning it analyzes data in motion.
Step-by-step explanation:
The statement 'The Nessus scanner scans data at rest, while the NNM monitors data in motion.' is false. Nessus is a widely known and utilized vulnerability scanner created by Tenable Network Security. It is used to identify vulnerabilities by scanning systems, networks, and applications for known weaknesses. On the other hand, the Network Noise Map (NNM), also from Tenable, observes and analyzes network traffic to detect anomalies, intruders, and potential threats. It thus monitors data in motion - that is, data being transmitted across the network. Nessus, in contrast, does not focus on data in motion or data at rest per se; it emphasizes identifying vulnerabilities that could be abused by attackers.
