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.

Extracting metadata from pdf documents

In this section, we review how to extract metadata from pdf documents with pyPDF2 module.

Introduction to PyPDF2

One of the modules available in Python to extract data from PDF documents is PyPDF2. The module can be downloaded directly with the pip install utility since it is located in the official Python repository .

In the https://pypi.org/project/PyPDF2/ URL, we can see the last version of this module:

This module offers us the ability to extract document information, and encrypt and decrypt documents. To extract metadata, we can use the PdfFileReader class and the getDocumentInfo() method, which returns a dictionary with the data of the document:

The following function would allow...
