Mastering Python for Networking and Security - Second Edition

By: José Ortega

Overview of this book

It’s now more apparent than ever that security is a critical aspect of IT infrastructure, and that devastating data breaches can occur from simple network line hacks. As shown in this book, combining the latest version of Python with an increased focus on network security can help you to level up your defenses against cyber attacks and cyber threats. Python is being used for increasingly advanced tasks, with the latest update introducing new libraries and packages featured in the Python 3.7.4 recommended version. Moreover, most scripts are compatible with the latest versions of Python and can also be executed in a virtual environment. This book will guide you through using these updated packages to build a secure network with the help of Python scripting. You’ll cover a range of topics, from building a network to the procedures you need to follow to secure it. Starting by exploring different packages and libraries, you’ll learn about various ways to build a network and connect with the Tor network through Python scripting. You will also learn how to assess a network's vulnerabilities using Python security scripting. Later, you’ll learn how to achieve endpoint protection by leveraging Python packages, along with writing forensic scripts. By the end of this Python book, you’ll be able to use Python to build secure apps using cryptography and steganography techniques.

Chapter 2: System Programming Packages

In this chapter, we continue to move forward with learning about the different ways we have to interact with the operating system and the filesystem. The knowledge you gain from this chapter about the different programming packages will prove to be very useful in automating certain tasks that can increase the efficiency of our scripts.

Throughout this chapter, we will look at the main modules we can find in Python for working with the Python interpreter, the operating system, and executing commands. We will review how to work with the filesystem when reading and creating files. Also, we’ll review thread management and other modules for multithreading and concurrency. We’ll end this chapter with a review of the socket.io module for implementing asynchronous servers.

The following topics will be covered in this chapter:

  • Introducing system modules in Python
  • Working with the filesystem in Python
  • Managing threads...
