CompTIA Security+ (SY0-701) — Question 246

An auditor discovered multiple insecure ports on some servers. Other servers were found to have legacy protocols enabled. Which of the following tools did the auditor use to discover these issues?

Answer options

• A. Nessus
• B. curl
• C. Wireshark
• D. netcat

Correct answer: A

Explanation

Nessus is a widely used vulnerability scanner that helps in identifying insecure ports and legacy protocols on servers, making it the correct choice. The other tools, while useful for different purposes, do not specialize in vulnerability scanning; curl is primarily for transferring data, Wireshark is for network traffic analysis, and netcat is a networking utility that does not focus on vulnerability assessment.
