Mastering Python for Networking and Security

By: José Ortega

Overview of this book

It’s becoming more and more apparent that security is a critical aspect of IT infrastructure. A data breach is a major security incident, usually carried out by just hacking a simple network line. Increasing your network’s security helps step up your defenses against cyber attacks. Meanwhile, Python is being used for increasingly advanced tasks, with the latest update introducing many new packages. This book focuses on leveraging these updated packages to build a secure network with the help of Python scripting. This book covers topics from building a network to the different procedures you need to follow to secure it. You’ll first be introduced to different packages and libraries, before moving on to different ways to build a network with the help of Python scripting. Later, you will learn how to check a network’s vulnerability using Python security scripting, and understand how to check vulnerabilities in your network. As you progress through the chapters, you will also learn how to achieve endpoint protection by leveraging Python packages along with writing forensic scripts. By the end of this book, you will be able to get the most out of the Python language to build secure and robust networks that are resilient to attacks.

Scan modes with python-nmap

In this section we review the scan modes supported in the python-nmap module. python-nmap allows for the automation of port scanner tasks and reports in two modes: synchronous and asynchronous. With the asynchronous mode, we can define a callback function that will execute when a scan is finished in a specific port and, in this function, we can make additional treatments if the port is opened, such as launching an Nmap script for a specific service (HTTP, FTP, MySQL).

Synchronous scanning

In this example, we implemented a class that allows us to scan an IP address and a list of ports that are passed to the script as a parameter.

In the main program, we add the necessary configuration for the treatment...
