NOTES
Nmap is often the first structured view of a network assessment. I use it to turn an address range into a working inventory of responsive hosts, exposed services, and version information that can guide more focused validation.
WORKFLOW
- Start with the least intrusive discovery needed for the scope and environment.
- Separate broad discovery from deeper service enumeration so results stay understandable.
- Save output in reusable formats instead of relying only on terminal scrollback.
- Revalidate important ports before reporting because network state changes.
LAB EXAMPLE
For your own lab host, a basic version-detection scan can be kept simple:
nmap -sV 192.0.2.10
Replace the documentation address only with a system you own or are authorized to test.
