What tool can be used for network vulnerability scanning?

• A. Nessus, OpenVAS, and Qualys
• B. MS Word, PowerPoint, and Excel
• C. Notepad, Paint, and PhotoShop
• D. Google Chrome, Firefox, and Safari

Answer: (A)

The choice highlighting Nessus, OpenVAS, and Qualys is correct because these tools are specifically designed for network vulnerability scanning. Each of them plays a crucial role in identifying security weaknesses within networked systems.

Nessus is a widely used vulnerability assessment tool that helps organizations determine the security posture of their networks, providing detailed analysis and reporting of vulnerabilities, including those related to outdated software, misconfigurations, and potential security threats.

OpenVAS is an open-source counterpart that also focuses on vulnerability scanning. It provides a comprehensive suite of tools and services for scanning and managing network vulnerabilities, allowing organizations to detect and mitigate risks effectively.

Qualys, similarly, offers a cloud-based platform for vulnerability management and is noted for its speed and efficiency in scanning large networks for vulnerabilities. It not only identifies vulnerabilities but also provides actionable remediation guidance.

In contrast, the other options consist of general-purpose software or web browsers that are not equipped for security assessments. MS Word, PowerPoint, and Excel are productivity applications, and Notepad, Paint, and PhotoShop are primarily for text editing and image manipulation. Google Chrome, Firefox, and Safari are web browsers used for accessing the internet rather than for scanning networks for vulnerabilities. Therefore, the only answer that aligns with the specific
