True or False: A Passive Vulnerability Scanner is simply a Network Intrusion Detection System (NIDS).

A Passive Vulnerability Scanner and a Network Intrusion Detection System (NIDS) are distinct in their functionalities and goals. A Passive Vulnerability Scanner is designed specifically to identify vulnerabilities within networked systems without actively probing them, making it less likely to disrupt operations. It passively monitors network traffic and analyses it to identify potential weaknesses, security misconfigurations, or compliance issues.

In contrast, a NIDS focuses on monitoring network traffic in real-time to detect and alert on suspicious activity that may indicate an ongoing attack. While both tools analyze data traffic, they serve different purposes: the scanner assesses for vulnerabilities, while the IDS seeks to detect intrusions.

Therefore, stating that a Passive Vulnerability Scanner is simply a NIDS is inaccurate, as they fulfill different roles in maintaining cybersecurity.
