2026 TryHackMe | Network Security - Post Port Scan | Walkthrough

Описание: 👉 Advanced Enumeration Techniques:
1. Service Detection (-sV): Probing open ports to determine the service name and version. We explore using --version-intensity (0-9) to balance speed and accuracy.
2. OS Detection (-O): Analyzing TCP/IP stack behavior to guess the target's operating system.
3. Nmap Scripting Engine (NSE): Leveraging -sC for default scripts or --script for specialized tasks like vulnerability scanning (vuln) or banner grabbing.
4. Traceroute mapping: Using --traceroute to visualize the network path and identify intermediate hops or firewalls.
5. Output Management: Mastering -oN (Normal), -oG (Grepable), and -oX (XML) to save results for reporting or automation.


In this 2026 TryHackMe Nmap: Post Port Scans walkthrough, we move beyond simple port discovery to extract high-value intelligence from our targets. This room is the final chapter of the Nmap series, focusing on the critical "What now?" phase after you've identified open ports.

We demonstrate how to use Nmap to fingerprint the exact versions of running services and identify the underlying operating system. These details are vital for a SOC Analyst or Penetration Tester, as they allow you to map your findings to specific CVEs and known exploits.
