NSE scripts are written in which language and extend Nmap with automated checks?

• A. NSE scripts are written in Python and extend Nmap with automated checks.
• B. NSE scripts run separately from Nmap to perform external scans.
• C. NSE scripts are written in Lua and extend Nmap with automated discovery and vulnerability checks.
• D. NSE scripts are only used for OS fingerprinting.

Answer: (C)

NSE scripts are written in Lua and run inside Nmap via the Nmap Scripting Engine, which lets you automate discovery and vulnerability checks as part of a scan. Lua is lightweight and embeddable, so scripts can access scan results and perform a wide range of checks without leaving Nmap. These scripts aren’t standalone Python programs, nor are they limited to OS fingerprinting; they extend Nmap to automate discovery, service checks, and various vulnerability assessments within a single scan.
