Overview of this book

Python’s latest updates add numerous libraries that can be used to perform critical security-related missions, including detecting vulnerabilities in web applications, taking care of attacks, and helping to build secure and robust networks that are resilient to them. This fully updated third edition will show you how to make the most of them and improve your security posture. The first part of this book will walk you through Python scripts and libraries that you’ll use throughout the book. Next, you’ll dive deep into the core networking tasks where you will learn how to check a network’s vulnerability using Python security scripting and understand how to check for vulnerabilities in your network – including tasks related to packet sniffing. You’ll also learn how to achieve endpoint protection by leveraging Python packages along with writing forensics scripts. The next part of the book will show you a variety of modern techniques, libraries, and frameworks from the Python ecosystem that will help you extract data from servers and analyze the security in web applications. You’ll take your first steps in extracting data from a domain using OSINT tools and using Python tools to perform forensics tasks. By the end of this book, you will be able to make the most of Python to test the security of your network and applications.

Summary

In this chapter, we learned about the main system modules for Python programming, including os for working with the operating system and subprocess for executing commands. We also reviewed how to work with the filesystem, managing threads, and concurrency.

After practicing with the examples provided in this chapter, you now have sufficient knowledge to automate tasks related to the operating system, access to the filesystem, and the concurrent execution of tasks.

In the next chapter, we will explore the socket package for resolving IP addresses and domains and implement clients and servers with the TCP and UDP protocols.
