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.

Connecting with SSH servers

In this section, we will review the Paramiko and pxssh modules that provide us with the necessary methods to create SSH clients in an easy way.

The Secure Shell (SSH) protocol

SSH has become a very popular network protocol for performing secure data communication between two computers. Both of the parts in communication use SSH key pairs to encrypt their communications. Each key pair has one private and one public key. The public key can be published to anyone who may be interested in that. The private key is always kept private and secure from everyone except the owner of the key.

Public and private SSH keys can be generated and digitally signed by a certification authority (CA). These keys can...
