FAQPage Schema
How do I scan for open TCP and UDP ports on a target network segment?

Port scanning identifies open TCP and UDP ports using tools like nmap and masscan. This Skill performs comprehensive network reconnaissance to discover active hosts and their open ports across the target segment.

What is the best way to detect running service versions and operating systems during network reconnaissance?

Service identification and OS fingerprinting detect running services and operating systems on open ports. This Skill uses nmap to perform detailed version detection during the reconnaissance phase.

Can I use masscan or rustscan for faster port scanning instead of nmap?

Yes, port scanning supports masscan and rustscan for speed-focused reconnaissance alongside nmap. You can select these tools to perform rapid network port scanning based on your specific detail and speed requirements.

How do I identify a target's attack surface when assessing a new network?

Network port scanning and service identification reveal a target's attack surface by discovering open ports. This Skill helps you prioritize further investigation on interesting services running across TCP and UDP protocols.

What is the difference between nmap and masscan for discovering open ports?

Nmap provides detailed service detection and OS fingerprinting, while masscan focuses on rapid port discovery. This Skill supports both tools to balance scanning speed and detail requirements during network reconnaissance.
