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.

Working with Nmap Scanners

This chapter covers how network scanning is done with python-nmap to gather information on a network, host, and the services that are running on the hosts. Some of the tools that allow a port scanner and automate the detection of services and open ports, we can find in Python, among which we can highlight python-nmap. Nmap is a powerful port scanner that allows you to identify open, closed, or filtered ports. It also allows the programming of routines and scripts to find possible vulnerabilities in a given host.

The following topics will be covered in this chapter:

  • Learning and understanding the Nmap protocol as a port scanner to identify services running on a host
  • Learning and understanding the python-nmap module that uses Nmap at a low level and is a very useful tool to optimize tasks related to port scanning
  • Learning and understanding synchronous...
