Approach for Monitoring Network Traffic for Vulnerabilities

D.

The approach taken by the security analyst is Passive Vulnerability Scanning, as they have set up a network tap to monitor network traffic. Passive vulnerability scanning involves the collection of data from the network without actively engaging with the systems or devices being scanned. Instead, it listens passively to network traffic and analyzes it to identify potential vulnerabilities.

Passive vulnerability scanning is a non-intrusive approach that allows security analysts to monitor network traffic for vulnerabilities without disrupting normal operations. By collecting data in this way, security analysts can identify potential threats and weaknesses in the network that could be exploited by attackers.

Compliance scanning, on the other hand, involves testing a network or system to ensure that it complies with specific security standards or regulations. Credentialed scanning is a method of vulnerability scanning that involves using credentials (such as usernames and passwords) to access systems and devices and identify vulnerabilities. Port scanning involves scanning a network for open ports to identify potential entry points for attackers.

In summary, the approach taken by the security analyst to monitor network traffic for vulnerabilities is Passive Vulnerability Scanning, which involves the collection and analysis of data from network traffic without actively engaging with the systems or devices being scanned.
