Key Application Areas
Network Security Assessment
Nmap is an essential tool for security professionals conducting network assessments:
# Comprehensive security scan of a subnet
nmap -A -T4 192.168.1.0/24 -oA security_assessment
This type of scan provides detailed information about hosts, services, and potential vulnerabilities.
System Administration
System administrators use Nmap for network maintenance and troubleshooting:
# Check which services are running on a server
nmap -sV -p 1-65535 server.example.com
This helps verify that only authorized services are accessible.
Penetration Testing
Penetration testers rely on Nmap during the reconnaissance phase:
# Stealthy scan to avoid detection
nmap -sS -T2 --script=vuln target.example.com
This provides valuable information about potential attack vectors.
