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.

Socket Programming

his chapter will introduce you to some of the basics of Python networking using the socket module. Along the way, we'll build clients, servers with TCP, and user datagram protocol (UDP) protocols. Sockets Programming covers using TCP and UDP sockets from Python for writing low-level network applications. We will also cover HTTPS and TLS for secure data transport.

The following topics will be covered in this chapter:

  • Understanding the sockets and how to implement them in Python
  • Understanding the TCP Programming Client and Server in Python
  • Understand the UDP Programming Client and Server in Python
  • Understand socket methods for resolving IP addresses and domains
  • Applying all concepts in practical uses cases, such as port scanning, and managing exceptions
