nmap -sV 192.168.1.1
Detects the version of services running on open ports.
4. OS Detection
nmap -O 192.168.1.1
Attempts to identify the operating system of the target.
5. Aggressive Scan
nmap -A 192.168.1.1
Enables OS detection, version detection, script scanning, and traceroute.
6. Vulnerability Scanning with NSE Scripts
nmap --script=vuln 192.168.1.1
Runs vulnerability detection scripts from the Nmap Scripting Engine (NSE).
7. Save Scan Results to a File
nmap -oN output.txt 192.168.1.1
Saves the scan results in a normal format to output.txt
.
8. Scan for Specific Vulnerabilities
nmap --script=http-sql-injection 192.168.1.1
Checks for SQL injection vulnerabilities on web servers.
