This is a Collaboration post with Cyber Security Mumbai.

Using Nmap for Port and Network scanning : A Comprehensive Guide.

As a cyber security professional, one of the most important tools in your arsenal is a network scanner.

Nmap, short for Network Mapper, is one of the most widely used and powerful network scanners available.

In this collaboration blog post with cybersecuritymumbai.com, we will explore how to use Nmap for port Scanning, network discovery, and more.

Nmap for port scanning

First, let's start with the basics of using Nmap for port scanning.

Nmap allows you to scan a specific host or range of IP addresses to determine which ports are open and listening.

This can be useful for identifying potential vilnerabilities in your network or for network inventory and mapping.

To perform a basic port scan with Nmap, simply use the command

 nmap [host or IP range]   #Normal Scanning
 nmap -F [hostname]   #Fast Scanning

However, Nmap offers many advance options for more detaild port scanning.

For example, you can use the ' -sS ' option to perform a stealth SYN scan, or the ' -sU ' option to perform a UDP scan.

 nmap -sU [hostname]   #Scanning UDP Protocols

You can also use the ' -p ' option to specify a specific range of ports to scan.

 nmap -sU -p- [hostname]  #Scanning for all Ports

Nmap for network discovery and mapping.

In addition to port scanning, Nmap can also be used for network discovery and mapping.

For example, the ' -sP ' option, allows you to perform a ping sweep to identify live gosts on a network.

 nmap -sP [hostname]   #Ping Scan

The ' -A ' option enables OS and services detection, allowing you to identify the type of devices and software running on a network.

 nmap -A [hostname]  #Scan OS information and Traceroute

Nmap for vulnerability scanning

Another important use of Nmap is for vulnerability scanning.

Nmap can be used in conjunction with the Nmap Scripting Engine (NSE) to perform vulnerability scans on a network.

The NSE allows you to run scropts vulnerabilities, such as the Hearbleed vulnerability in OpenSSL.

Nmap for network inventory and mapping

Finally, Nmap can also be used for network inventory and mapping. By using Nmap to scan a network, you can create a map of all devices and software russing on the network.

This can be useful for identifying potential security risks, for network planning, and for troubleshooting network issues.

In conclusion, Nmap is a powerful tool for cybersecurity professionals and network administators.

With the ability to perform port scanning, network discovery, vulnerability scanning, and more, Nmap is a valuable tool for any network security toolkit.
