Identifying and Assessing Nmap-Discovered Vulnerabilities
Nmap Scanning Techniques
Nmap offers a variety of scanning techniques to identify vulnerabilities on a target network. Some common techniques include:
- TCP SYN Scan
- UDP Scan
- Idle/Zombie Scan
- Idle/Zombie Scan
These scanning techniques can be used to gather information about the target network, including open ports, running services, and potential vulnerabilities.

Vulnerability Assessment with Nmap
Nmap can be used to assess the identified vulnerabilities and determine their severity. This can be done using Nmap's built-in vulnerability detection capabilities, as well as by integrating Nmap with external vulnerability databases and tools.
Nmap Vulnerability Scanning
Nmap's --script
option allows you to run various vulnerability detection scripts against the target network. These scripts can identify known vulnerabilities, misconfigurations, and other security issues.
Example command:
nmap -sV --script=vuln <target_ip>
Integrating with Vulnerability Databases
Nmap can be integrated with external vulnerability databases, such as the National Vulnerability Database (NVD), to provide more detailed information about the identified vulnerabilities.
