Exploring Nmap Scan Types and Options

Now that Nmap is installed on your Kali Linux system, let’s explore the different scan types and options available to enhance your security scanning capabilities. Nmap is a powerful tool that offers a wide range of scanning techniques, allowing you to gather valuable information about your network and its vulnerabilities.

Scan Types

Nmap provides several scan types that can be used to analyze different aspects of your network. Here are some of the most commonly used scan types:

• Ping Scan: This scan determines if a host is online by sending ICMP echo requests. It is a quick way to check the availability of hosts on your network.
• TCP SYN Scan: This scan examines open ports on a target system by using the TCP SYN packet. It is considered stealthier than other scan types.
• UDP Scan: This scan focuses on UDP ports and can be used to identify services that may be running on non-standard ports.
• Comprehensive Scan: This scan combines several techniques to provide a detailed overview of a target system, including port scanning, OS detection, service enumeration, and script scanning.
• Custom Port Scan: This scan allows you to define specific ports or port ranges to scan, giving you more control over the scanning process.

Scan Options

In addition to the scan types, Nmap offers various scan options that allow you to fine-tune your scanning activities. These options provide flexibility and customization to meet your specific needs. Here are some of the commonly used scan options:

“-sV”: Enables service version detection, providing information about the services running on open ports.
