Which of the following is a common vulnerability assessment tool?

Nessus is recognized as a prominent vulnerability assessment tool, widely used in the field of network security for identifying and addressing vulnerabilities within systems. It operates by scanning networks and systems for known vulnerabilities, misconfigurations, and potential security weaknesses. Nessus provides detailed reports on the vulnerabilities found, which helps security professionals prioritize their remediation efforts effectively.

This tool stands out for its comprehensive database of vulnerabilities and regular updates, allowing it to stay current with emerging threats. Its user-friendly interface and robust functionality make it suitable for various environments, whether for individual systems or enterprise-level assessments. Using Nessus can significantly enhance an organization's security posture by proactively identifying areas that require attention, ensuring that vulnerabilities are managed before they can be exploited by potential attackers.

In contrast, the other tools listed serve different purposes within the broader network security landscape. Wireshark is primarily a network protocol analyzer used for capturing and analyzing network packets, while Snort is an intrusion detection and prevention system. Kali Linux is a specialized Linux distribution that contains a wide array of security tools, including Nessus, but it is not a vulnerability assessment tool on its own.
