One of the powerful features of Nmap is its ability to use scripts to automate scanning, extend functionality, and identify vulnerabilities in network targets. Nmap scripts are small programs that are executed concurrently with Nmap and can be used for various tasks in network analysis and security assessments. Nmap provides ready-made scripts for different purposes, such as vulnerability detection, service mapping, and network reconnaissance. Script files are usually located in the "scripts" directory of Nmap, which can be found in the installation folder of Nmap.

### A few examples

Perform a comprehensive cybersecurity audit:

```sh
nmap --script vuln <network address>
```

Check the strength of SSL/TLS security level:

```sh
nmap --script ssl-enum-ciphers <network-address>
```

You can also create your own scripts to better meet your needs and the testing environment. Nmap scripts are an effective way to expand Nmap's functionality and enhance security in network scanning.


An introduction to Nmap scripts

Nmap is one of the most well-known tools that you can use to perform versatile network scans. Every information security professional should know how to use this tool.

Nmap is one of the most well-known network scanning tools, often used by cybersecurity experts. In this course, we will learn how to use this tool and explore its capabilities. Additionally, we will examine the traffic generated by the tool and analyze the pros and cons of different scanning methods. It is beneficial to have an understanding of how networks operate in this course.

Warning! - Conducting network scans without permission may cause system malfunctions and/or crashes. Please refrain from attempting to scan any address/system without certainty that said system is in your possession or that you have permission to do so.
