| Recon | nmap -sV -sC -p- <target> | Full port/service scan |
| Enumeration | nmap --script <service>-* -p <port> <target> | Service-specific NSE scripts |
Notes
Always start with full port scan: `nmap -sV -sC -p- <target>`.
Check for default credentials before brute-forcing.
Use service-specific NSE scripts: `nmap --script <service>-* -p <port> <target>`.
Remember to check both IPv4 and IPv6 if applicable.
