Mastering Python for Networking and Security - Second Edition

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.

Questions

As we conclude, here is a list of questions for you to test your knowledge regarding this chapter's material. You will find the answers in the Assessments section of the Appendix:

  1. Which method from ftplib do we need to use to download files and which FTP command do we need to execute?
  2. Which method of the paramiko module allows us to connect to an SSH server and with what parameters (host, username, and/or password)?
  3. Which method of the paramiko module allows us to open a session to be able to execute commands subsequently?
  4. What is the instruction for informing paramiko to accept server keys for the first time without interrupting the session or prompting the user?
  5. What is the class we need to use to create our own SSH server using the create_server() method from the asyncssh module?
