# Scanning Network with Nmap Advanced Techniques
## When to Use
- Performing comprehensive asset discovery across large enterprise networks during authorized assessments
- Enumerating service versions and configurations to identify outdated or vulnerable software
- Bypassing firewall rules and IDS during authorized penetration tests using scan evasion techniques
- Scripting automated vulnerability checks using the Nmap Scripting Engine (NSE)
- Generating structured scan output for integration into vulnerability management pipelines
**Do not use** against networks without explicit written authorization, on production systems during peak hours without approval, or to perform denial-of-service through aggressive scan timing.
## Most Often Missed & How to Confirm
- **UDP is the silent gap:** a TCP-only scan misses SNMP (161), DNS (53), TFTP (69), IKE (500), NTP (123). Run `nmap -sU --top-ports 200` (slow, but those services are often the foothold); skipping UDP is the most common under-report.
