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.

Introduction to sockets

Sockets are the main component that allows us to take advantage of the operating system's capabilities to interact with the network. You can think of sockets as a point-to-point communication channel between a client and a server.

Network sockets are an easy way to establish a communication between processes that are on the same or different machines. The concept of a socket is very similar to that of UNIX file descriptors. Commands such as read() and write() ( to work with the file system ) work in a similar way to sockets.

A network socket address consists of an IP address and port number. The goal of a socket is to communicate processes through the network.
