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.

Using python to obtain server information

In this section, you will learn the basics of obtaining banners and whois information from servers with socket and python-whois modules.

Extracting servers banners with python

Banners expose information related with the name of the web server and the version that is running on the server. Some expose the backend technology (PHP, Java, Python) used and its version. The production version could have public or non-public failures, so it is always a good practice to test the banners that return the servers that we have publicly exposed, to see whether they expose some type of information that we do not want to be public.

Using the standard Python libraries, it is possible to create a...
