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.

Encrypting and decrypting information with cryptography

In this section, we review the cryptography module for encrypting and decrypting data. Cryptography is a module more recent and it has better performance and security than pycrypto.

Introduction to cryptography

Cryptography is available in the pypi repository and you can install with the pip install cryptography command.

In the https://pypi.org/project/cryptography URL, we can see the last version of this module.

For more information about installation and supported platforms, check out https://cryptography.io/en/latest/installation/.

Cryptography includes both high-level and low-level interfaces to common cryptographic algorithms, such as symmetric ciphers, message...
