Enumeration on Metasploitable2 Using Nmap – Cyber Security Practical

This practical guide details how to perform enumeration on a Metasploitable2 vulnerable server using Kali Linux. It explains VirtualBox network setup and step-by-step Nmap commands to discover open ports and service versions. Coverage includes FTP, SSH, Telnet, SNMP, SMTP, MySQL, HTTP and SSL, plus Nmap NSE scripts for authentication, user enumeration, brute-force checks and SSL/cipher analysis. Example commands and usage notes clarify when scans are intrusive and require permission. Ideal for information security students and lab exercises, this document helps learners gain hands-on experience with service discovery, vulnerability reconnaissance and preparing findings for later exploitation or remediation and reporting practices.
