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.

Creating a simple TCP client and TCP server

The idea behind creating this application is that a socket client can establish a connection against a given host, port, and protocol. The socket server is responsible for receiving connections from clients in a specific port and protocol.

Creating a server and client with sockets

To create a socket, the socket.socket() constructor is used, which can take the family, type, and protocol as optional parameters. By default, the AF_INET family and the SOCK_STREAM type are used.

In this section, we will see how to create a couple of client and server scripts as an example.

The first thing we have to do is create a socket object for the server:

server = socket.socket(socket.AF_INET, socket...
