Which tool is commonly used for penetration testing, port scanning, and enumeration?

• A. Wireshark
• B. OpenVAS
• C. Nmap
• D. Burp Suite

Answer: (C)

Nmap is a versatile network mapper used in penetration testing to discover live hosts, open ports, and the services running on them, while also gathering version and OS information to aid enumeration. Its port scanning capabilities cover multiple scan types (such as stealthy SYN scans, TCP connect scans, and UDP scans) to determine what is reachable on a target and how it’s configured. The real strength for pentesting comes from its service version detection and the Nmap Scripting Engine, which can automatically probe for specific configurations, misconfigurations, or common vulnerabilities. This combination lets you map the attack surface efficiently and plan subsequent exploitation or validation steps. Other tools have narrower purposes: Wireshark analyzes captured network traffic, OpenVAS focuses on vulnerability scanning, and Burp Suite targets web applications. Nmap uniquely brings together discovery, port enumeration, and broad enumeration capabilities in one tool, making it the best fit for this scenario.
