Tackle security and networking issues using Python libraries such as Nmap, requests, asyncio, and scapy

▶Book Description
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.

▶What You Will Learn
-Create scripts in Python to automate security and pentesting tasks
-Explore Python programming tools that are used in network security processes

▶What this book covers
- Chapter 1, Working with Python Scripting, introduces you to the Python language, object-oriented programming, data structures, exceptions, managing dependencies for developing with Python, and development environments.

- Chapter 2, System Programming Packages, teaches you about the main Python modules for system programming, looking at topics including reading and writing files, threads, sockets, multithreading, and concurrency.

- Chapter 3, Socket Programming, provides you with some basics of Python networking using the socket module. This module exposes all of the necessary pieces to quickly write TCP and UDP clients, as well as servers for writing low-level network applications.

- Chapter 4, HTTP Programming, covers the HTTP protocol and the main Python modules, such as the urllib standard library, and the requests and httpx modules to retrieve and manipulate web content. We also cover HTTP authentication mechanisms and how we can manage them with the requests module.

- Chapter 5, Connecting to the Tor Network and Discovering Hidden Services, explains how Tor can assist us in the research and development of tools from an anonymity and privacy point of view. In addition, we will review how to extract information from hidden services using Python modules.

- Chapter 6, Gathering Information from Servers, explores the modules that allow the extraction of information that servers are exposing publicly, such as Shodan and Binary Edge. We will also look at getting server banners and information on DNS servers and introduce you to fuzzy processing using the pywebfuzz module.

- Chapter 7, Interacting with FTP, SFTP, and SSH Servers, details the Python modules that allow us to interact with FTP, SFTP, and SSH servers, checking the security in SSH servers with the ssh-audit tool. Also, we will learn how to implement SSH clients and servers with the asyncSSH and asyncio modules.

- Chapter 8, Working with Nmap Scanner, introduces Nmap as a port

출판사 서평

▶ Preface
Recently, Python has started to gain a lot of traction, with the latest updates of Python adding numerous packages that can be used to perform critical missions. Our main goal with this book is to help you leverage Python packages to detect vulnerabilities and take care of networking challenges.

This book will start by walking you through the scripts and libraries of Python that are related to networking and security. You will then dive deep into core networking tasks and learn how to take care of networking challenges. Later, this book will teach you how to write security scripts to detect vulnerabilities in your network or website. By the end of this book, you will have learned how to achieve endpoint protection by leveraging Python packages, along with how to extract metadata from documents and how to write forensics and cryptography scripts.
